to install the plugin:
|
||||
- copy the directory 'nefit' to the domoticz/plugins directory
|
||||
- make sure that 'Accept new Hardware Devices' is enabeled in settings/sysem
|
||||
- create new hardware with type 'Nefit EMS-ESP with Proddy firmware'
|
||||
- set MQTT server and port
|
||||
|

The plugin crrently creates 3 devices:
|

- a room temperature meter
|
||||
- a system pressure meter
|
||||
- a thermostat setpoint control
