Using Domoticz to automate Tasmota based on Deye data

[JustinB]

Hi all

Background - I've flashed a handful of switches with Tasmota and installed a Deye inverter with PV to drive most of the house's load. In addition, i have a specific 3kva backup on a specific plug point. I also have a Pi running Domoticz and Mosquitto.

My intention is to capture the data from the Deye, and, based on that information, switch certain switches on or off. More specifically, if utility power is down, and load is exceeding PV, turn off the plug point driving the 3kva backup.

The Deye uses Solarman app/web - however this is only updated ~60 seconds or so. A potential solution would be to use the RS485 port to connect to a RS485-to-TTL connected to a ESP32 module, transmitting the RS485 feed to Mosquitto.

Is this the easiest solution - or am i missing something?

This says you can use modbus with the Deye. If Domoticz supports modbus, then that is the way to go. I know Home Assistant support modbus.

Domoticz supports Modbus too.

Sorry, the part I forgot in the story is that I cannot run a hardline to the inverter. So I need a wireless solution.

Cant or too much effort involved?

Well I guess I could drill through walls. Yes, that is too much effort considering the location of the router, Pi and inverter.

Huge thread on doing exactly this, not a walk in the park at this point in time unfortunately.

Thanks. I thought this would be easy... But clearly I've underestimated this.
