I was unable to get the examples above working when using that degree symbol in the unit of measurement, removing that symbol fixed the problem. I did try pasting in a fresh degree symbol, and even tried using one from the HASS front end, but that didn't work. However, this example has been here for a long time and I can't find any other cases of complaints, so I figured i'd add a warning in the comments in case anyone else has the same problem.
Before finding this guide, I ran into the Port 80 problem described in this page (likely blocked by ISP) and [posted about it in the LetsEncrypt forums](https://community.letsencrypt.org/t/help-with-standalone-certbot-failed-to-bind-to-80-using-ipv4/37701/8). While this excellent guide helped me circumvent that immediate issue, a certbot engineer suggested an alternate method for automated cert renewal that did not require manually changing port mapping every time a cert needed to be renewed.
In short, he suggested using a TLS challenge rather than HTTP, so that the Let's Encrypt CA would bind port 443 externally, and specify certbot to bind to port 8123 internally for certificate renewal. He also added that pre- and post-hooks could be passed to certbot so that HA could be stopped/started and port 8123 could be freed for cert renewal.
I have verified that this method works in a dry run on my own HA setup and modified step 8 with some suggested documentation
* Added note about RPi's 100 mbit limit
In my case, I just realized after months that RPi hav 100 mbit card, so this was the limiting factor :)
* Update
* Optional variables added to sensor.cups.markdown
Sensor configuration supports two additional variables which are not listed but would be extremely helpful to anyone running their print server on a host other than the one running Home Assistant.
Added two lines to the Configuration variables section to show host and port optional values.
* Fix formatting
* Add periods
* Update sensor.buienradar.markdown
update buienradar sensor documentation for updated sensor code (reverse winddirection / windazimuth); update the definition of the unit of precipitation_forecast_total
* Update sensor.buienradar.markdown
* resolve conflict
