I have an ESP8266 and an EcoSmart27 Hot water heater that I would love to control but I am not understanding the repo and how to implement it with my HomeAssistant setup. I have the ESPHome addon and have successfully got a relay working but I am less familiar with MQTT.
I am hoping someone here could offer guidance in order to help get me going.
I updated the repo with ESPHome-specific instructions; it should be a bit easier to integrate now.
As always, I make no warranties as to whether this will work for you - but it did work for me on my particular model. And watch out connecting those control wires! I fried a controller just looking at it funny.
One thing I didn’t mention is that the metal enclosure of the EcoSmart was really a hindrance to the nodemcu wifi signal. I had to place an AP pretty close to it to get it to work. I also could have brought the control wires through the case and placed the nodemcu on the outside.
I attempted an install but got stuck a bit. First error I got was with the status pin declaration. I changed D0 to 0 and the error went away.
Then I got an error when compiling where I get an error about BinarySensor.

I went ahead and commented out the binary_sensor and the climate sections of the yaml and attempted to recompile. I then got new errors (several) this time with regard to ecosmart.h

Unfortunately I lost my EcoSmart heater in a wildfire (not caused by the heater), so maintenance is not my priority at this point, but when I re-implement it I will try to work out the bugs. Are you using the ecosmart.h file from the ecosmart directory?
