New plugin for EMMETI Mirai SMi heat pumps

Post by psubiaco »

I've just published a plugin to interface (by RS485/Modbus) EMMETI MIRAI SMI heat pumps, so now it's quite easy to:
* monitor main parameters
* control heat pump, for example to optimize the self-consumption (if you have photovoltaic on the roof) by modulating the compressor frequency (power usage), outlet temperature and hot water setpoint.

Check the plugin page at https://github.com/CreasolTech/domoticz-emmeti-mirai

I want to thanks:
* Patrick Hamers that give me the idea to write the plugin, starting from his recent plugin for SPRSUN heat pump
* Domoticz developers, because I can say that developing a python plugin for Domoticz is really really easy (I tried in the past to develop a hardware integration for Home Assistant, but it's much much much more difficult and complicated with HA!).

This is another screenshot of my roomplan with some controls of the Emmeti Mirai heat pump.
A LUA script sets the compressor level and outlet water temperature to maximize the own consumption: as the photovoltaic increases the generated power, the compressor level increases as like as the outlet temperature.
