2016-08-31T04:17:25+00:00 + https://home-assistant.io/blog/2016/08/31/esp8266-and-micropython-part2 + +So, part 1 of ESP8266 and MicroPython was pretty lame, right? Instead of getting information out of Home Assistant we are going a step forward and create our own sensor which is sending details about its state to a Home Assistant instance.

+ + + +

Beside HTTP POST requests, MQTT is the quickest way (from the author’s point of view) to publish information with DIY devices.

+ +

You have to make a decision: Do you want to pull or to poll? For slowly changing values like temperature it’s perfectly fine to wait a couple of seconds to retrieve the value. If it’s a motion detector the state change should be available instantly. This means the sensor must take initiative.

+ +

An example for pulling is aREST. This is a great way to work with the ESP8266 based units and the Ardunio IDE.

+ +

MQTT

+ +

You can find a simple examples for publishing and subscribing with MQTT in the MicroPython library overview in the section for umqtt.

+ +

The example below is adopted from the work of @davea as we don’t want to re-invent the wheel. The configuration feature is crafty and simplyfies the code with the usage of a file called /config.json which stores the configuration details. The ESP8266 device will send the value of a pin every 5 seconds.

+ +
import machine
+import time
+import ubinascii
+import webrepl
+
+from umqtt.simple import MQTTClient
+
+# These defaults are overwritten with the contents of /config.json by load_config()
+CONFIG = {
+    "broker": "192.168.1.19",
+    "sensor_pin": 0, 
+    "client_id": b"esp8266_" + ubinascii.hexlify(machine.unique_id()),
+    "topic": b"home",
+}
+
+client = None
+sensor_pin = None
+
+def setup_pins():
+    global sensor_pin
+    sensor_pin = machine.ADC(CONFIG['sensor_pin'])
+
+def load_config():
+    import ujson as json
+    try:
+        with open("/config.json") as f:
+            config = json.loads(f.read())
+    except (OSError, ValueError):
+        print("Couldn't load /config.json")
+        save_config()
+    else:
+        CONFIG.update(config)
+        print("Loaded config from /config.json")
+
+def save_config():
+    import ujson as json
+    try:
+        with open("/config.json", "w") as f:
+            f.write(json.dumps(CONFIG))
+    except OSError:
+        print("Couldn't save /config.json")
+
+def main():
+    client = MQTTClient(CONFIG['client_id'], CONFIG['broker'])
+    client.connect()
+    print("Connected to {}".format(CONFIG['broker']))
+    while True:
+        data = sensor_pin.read()
+        client.publish('{}/{}'.format(CONFIG['topic'],
+                                          CONFIG['client_id']),
+                                          bytes(str(data), 'utf-8'))
+        print('Sensor state: {}'.format(data))
+        time.sleep(5)
+
+if __name__ == '__main__':
+    load_config()
+    setup_pins()
+    main()
+
+
+ +

Subscribe to the topic home/# or create a MQTT sensor to check if the sensor values are published.

+ +
$ mosquitto_sub -h 192.168.1.19 -v -t "home/#"
+
+
+ +
sensor:
+  - platform: mqtt
+    state_topic: "home/esp8266_[last part of the MAC address]"
+    name: "MicroPython"
+
+
+ +

@davea created sonoff-mqtt. This code will work on ESP8622 based devices too and shows how to use a button to control a relay.

That’s why @jbags81 recently introduced the all-in-one installer. It allows you to get up and running with a complete Home Assistant setup by entering one line of code into your Raspberry Pi running Raspbian Jessie:

- -
wget -Nnv https://raw.githubusercontent.com/home-assistant/fabric-home-assistant/master/hass_rpi_installer.sh && bash hass_rpi_installer.sh;
-
-
- -

This feature wouldn’t be complete if it wasn’t accompanied by a new video by Ben from BRUH Automation. The video shows how to install Raspbian Jessie on your Raspberry Pi and use the new installation script to get a full Home Assistant system up and running.

    ESP8266 and MicroPython - Part 2

    + +
    + + +

    +So, part 1 of ESP8266 and MicroPython was pretty lame, right? Instead of getting information out of Home Assistant we are going a step forward and create our own sensor which is sending details about its state to a Home Assistant instance.

    + + + +

    Beside HTTP POST requests, MQTT is the quickest way (from the author’s point of view) to publish information with DIY devices.

    + +

    You have to make a decision: Do you want to pull or to poll? For slowly changing values like temperature it’s perfectly fine to wait a couple of seconds to retrieve the value. If it’s a motion detector the state change should be available instantly. This means the sensor must take initiative.

    + +

    An example for pulling is aREST. This is a great way to work with the ESP8266 based units and the Ardunio IDE.

    + +

    MQTT

    + +

    You can find a simple examples for publishing and subscribing with MQTT in the MicroPython library overview in the section for umqtt.

    + +

    The example below is adopted from the work of @davea as we don’t want to re-invent the wheel. The configuration feature is crafty and simplyfies the code with the usage of a file called /config.json which stores the configuration details. The ESP8266 device will send the value of a pin every 5 seconds.

    + +
    import machine
+import time
+import ubinascii
+import webrepl
+
+from umqtt.simple import MQTTClient
+
+# These defaults are overwritten with the contents of /config.json by load_config()
+CONFIG = {
+    "broker": "192.168.1.19",
+    "sensor_pin": 0, 
+    "client_id": b"esp8266_" + ubinascii.hexlify(machine.unique_id()),
+    "topic": b"home",
+}
+
+client = None
+sensor_pin = None
+
+def setup_pins():
+    global sensor_pin
+    sensor_pin = machine.ADC(CONFIG['sensor_pin'])
+
+def load_config():
+    import ujson as json
+    try:
+        with open("/config.json") as f:
+            config = json.loads(f.read())
+    except (OSError, ValueError):
+        print("Couldn't load /config.json")
+        save_config()
+    else:
+        CONFIG.update(config)
+        print("Loaded config from /config.json")
+
+def save_config():
+    import ujson as json
+    try:
+        with open("/config.json", "w") as f:
+            f.write(json.dumps(CONFIG))
+    except OSError:
+        print("Couldn't save /config.json")
+
+def main():
+    client = MQTTClient(CONFIG['client_id'], CONFIG['broker'])
+    client.connect()
+    print("Connected to {}".format(CONFIG['broker']))
+    while True:
+        data = sensor_pin.read()
+        client.publish('{}/{}'.format(CONFIG['topic'],
+                                          CONFIG['client_id']),
+                                          bytes(str(data), 'utf-8'))
+        print('Sensor state: {}'.format(data))
+        time.sleep(5)
+
+if __name__ == '__main__':
+    load_config()
+    setup_pins()
+    main()
+
    +
    + +

    Subscribe to the topic home/# or create a MQTT sensor to check if the sensor values are published.

    + +
    $ mosquitto_sub -h 192.168.1.19 -v -t "home/#"
+
    +
    + +
    sensor:
+  - platform: mqtt
+    state_topic: "home/esp8266_[last part of the MAC address]"
+    name: "MicroPython"
+
    +
    + +

    @davea created sonoff-mqtt. This code will work on ESP8622 based devices too and shows how to use a button to control a relay.

This means that you have access to all stored information about your home. Our history is not a full-fledged graphical processing and visualization component as you may know from systems and network monitoring tools. The current limitation is that you only can select a day for a visual output of your information and not a period. Also, there is no possibility to drill down on a specific entity. - -This blog post will show you ways to export data for reporting, visualization, or further analysis of automation rules. - - - -In this blog post I use the temperature of the [Aare](https://en.wikipedia.org/wiki/Aare) river close to where I live as a show case. The temperatures were recorded with the [Swiss Hydrological Data sensor](/components/sensor.swiss_hydrological_data/) and the name of the sensor is `sensor.aare`. - -The database is stored at `/.homeassistant/home-assistant_v2.db` as [SQLite database](https://www.sqlite.org/). In all examples we are going to use the path: `/home/ha/.homeassistant/home-assistant_v2.db` - -If you are just curious what's stored in your database then you can use the `sqlite3` command-line tool or a graphical one like [DB Browser for SQLite](http://sqlitebrowser.org/). - -The table that is holding the states is called `states`. The `events` tables is responsible for storing the events which occurred. So, we will first check how many entries there are in the `states` table. `sqlite3` needs to know where the databases is located. To work with your database make sure that Home Assistant is not running or create a copy of the existing database. It's recommended to work with a copy. - -```bash -$ sqlite3 /home/ha/.homeassistant/home-assistant_v2.db -SQLite version 3.11.0 2016-02-15 17:29:24 -sqlite> SELECT count(*) FROM states; -24659 -``` - -Let's have a look at a sample [SQL](https://en.wikipedia.org/wiki/SQL) query.

This means that you can process the data in any way you want for further use. Often it makes sense to eliminate certain entries like `Unknown` or peaks. - -If the above query is executed in DB Browser for SQLite you would be able to save the sensor's graph as png. - -

    - -You may ask: Why not do this with LibreOffice Calc or another spreadsheet application? As most spreadsheet applications are not able to work directly with SQLite database we are going to export the data from the database to [CSV](https://en.wikipedia.org/wiki/Comma-separated_values). - -```bash -$ sqlite3 -header -csv /home/ha/.homeassistant/home-assistant_v2.db "SELECT last_changed, state FROM states WHERE entity_id = 'sensor.aare' AND last_changed BETWEEN '2016-07-05 00:00:00.000000' AND '2016-07-07 00:00:00.000000';" > sensor.csv -``` - -The ordering for the `SELECT` was changed to get the time stamps first and then the state. Now we can import the CSV file into the application of your choice, here it's LibreOffice Calc. - -

    - - Import of the CSV file -

    - -After the import a graph can be created over the existing data. - -

    - - Graph in LibreOffice -

    - -You can also use [matplotlib](http://matplotlib.org/) to generate graphs as an alternative to a spreadsheet application. This is a powerful Python 2D plotting library. With the built-in support for SQLite in Python it will only take a couple lines of code to visualize your data. - -```python -import sqlite3 -from matplotlib import dates -import matplotlib.pyplot as plt - -import homeassistant.util.dt as dt - -values = [] -timestamps = [] - -conn = sqlite3.connect('/home/ha/.homeassistant/home-assistant_v2.db') -data = conn.execute("SELECT state, last_changed FROM states WHERE " - "entity_id = 'sensor.aare' AND last_changed BETWEEN " - "'2016-07-05 00:00:00.000000' AND " - "'2016-07-07 00:00:00.000000'") - -for x in data: - timestamps.append(dates.date2num(dt.parse_datetime(x[1]))) - values.append(float(x[0])) - -plt.plot_date(x=timestamps, y=values, fmt="r-") -plt.ylabel('Temperature') -plt.xlabel('Time line') - -plt.savefig('sensor.png') -``` - -Creating a connection to the database and executing a query is similar to the ways already seen. The return values from the query are splitted into two lists. The time stamps must be converted in an value which is accepted by matplotlib and then the graph is generated and saved as image. - -

    - - Sensor graph generated by matplotlib -

    The history component is tracking everything that is going on within Home Assistant. This means that you have access to all stored information about your home. Our history is not a full-fledged graphical processing and visualization component as you may know from systems and network monitoring tools. The current limitation is that you only can select a day for a visual output of your information and not a period. Also, there is no possibility to drill down on a specific entity.

    We are always hard at work at the virtual Home Assistant headquarters to make it easier for you to get started with Home Assistant. That’s why @jbags81 recently introduced the all-in-one installer. It allows you to get up and running with a complete Home Assistant setup by entering one line of code into your Raspberry Pi running Raspbian Jessie:

    - -
    wget -Nnv https://raw.githubusercontent.com/home-assistant/fabric-home-assistant/master/hass_rpi_installer.sh && bash hass_rpi_installer.sh;
-

    This feature wouldn’t be complete if it wasn’t accompanied by a new video by Ben from BRUH Automation. The video shows how to install Raspbian Jessie on your Raspberry Pi and use the new installation script to get a full Home Assistant system up and running.

    Another awesome release ready to hit your homes. YAML can be hard for beginners and more experienced automators. So to help catch those pesky errors that sneak into your files we’ve been hard at work to introduce config validation! Especially huge thanks to @jaharkes for his hard work on this. Config validation is still in it’s early stages. More common platforms and components have been added but we didn’t do everything yet.

    - -

    When we encounter an invalid config we will now write a warning to your logs. You can see those in the frontend by clicking on the last developer tool. We’re looking into options to make it more clear - it is a work in progress.

    - -

    Another big thing is the addition of GTFS support. You probably don’t know it, but GTFS is the standard that public transit companies all over the world use to distribute their schedule. This means that you can now have the time of the next bus/train/etc right in your frontend.

    As of now we are not aware of any breaking changes. However, it might be that Home Assistant will not start for you because of an invalid configuration. A common mistake that people are making is that they are still referring to execute_service in their script configs. This should be service.

    This is a guest post by Home Assistant users Jeremiah Wuenschel and St. John Johnson.

    - -

    So you own a SmartThings Hub. You probably bought it when you were looking to get into the whole Home Automation hobby because it worked with pretty much everything and offered you the ability to automate anything. After a week of ownership, you realized that building dashboards and automating required writing way more Groovy then you expected. Then one day you were browsing reddit and discovered the amazingness that is Home Assistant! A solution that offered dashboards, graphs, working support for Nest, and REAL EASY automation!

    - -

    You spent your weekend getting everything set up, showing it off to your significant other, but in the end you got stumped when it came to integrating with all your existing SmartThings toys. What do I do now? Should I buy another hub? Should I just buy a Z-Wave stick?

    - -

    That’s where we came in. We wanted a solution that can bridge the awesomeness of Home Assistant with the SmartThings hub that works with almost everything.

    From time to time we come along things that are worth sharing with fellow Home Assisters. Here a list of some cool stuff from last week:

    - -

    First is the public beta of Let’s Encrypt. Let’s Encrypt is a new certificate authority that is free, automated and open. This means that it will now be very easy to secure your connection to Home Assistant while you are away from home. W1ll1am23 has written up a guide how to get started.

    - -

    The next thing is a show-off of some of the cool stuff people do with Home Assistant. This is miniconfig talking to Home Assistant using the Amazon Echo!

    MQTT support was added to Home Assistant recently. The MQTT component will enable you to do all sort of things. Most likely you will use it to communicate with your devices. But Home Assistant doesn’t care where the data is coming from or is limited to real hardware as long as there is MQTT support. This means that it doesn’t matter if the data is coming from a human, a web service, or a device.

    - -

    A great example is shown in a Laundry Automation post in this blog.

    This post will give you a small overview of some other possibilities on how to use MQTT with Home Assistant.
