The `modbus` thermostat allows you to use a sensor value (current temperature)
|
|
and target value (target temperature) from [Modbus](http://www.modbus.org/)
|
|
registers.
|
|
|
|
To use your Modbus thermostat in your installation, add the following to your `configuration.yaml` file:
|
|
|
|
```yaml
|
|
climate:
|
|
- platform: modbus
|
|
name: Watlow F4T
|
|
slave: 1
|
|
target_temp_register: 2782
|
|
current_temp_register: 27586
