Dear all,
I’m in the migration from another system (so, new ho hass). In that process I want to migrate an energy meter, connected via MQTT. I’m completely free in how to create the messages (topic+payload) and want setup the sending edge in a way that it is best supporting HA MQTT discovery, or - so that HASS may understand in the best possible way how to setup/use the entities sending.
The device deliveres: energy as total (kWh) and current consumption (W). Also a mains frequency sensor (Hz). Gas and Water (essentially an impuls counter, so bonus would be the chance to set/updates values from HA).
I kindly ask for advice and wishdom:
- how should the mqtt topic be structured in a most ideal way?
- how the payload?
to support the autodiscovery feature best (make HA understand what devices this are and use “in the most natural HA way”)
Also: a fan (the V in HVAC) is connected. Here I would follow the recommendations in MQTT Fan - Home Assistant (home-assistant.io) ?
I admit that I not fully understand (yet) what, from the options provided there, I have to use as “best practise”.
Examples for the optimal mqtt message structure (topics+payload) are highly welcome.
many thanks fro advice, best
joerg
