i bring portable air conditioning from Kesser to HA
esp8266 d1-mini
8-way relays, 7 of which are in use
DS18B20 temperature sensor
water level sensor
Power supply 220V to 5V
The display is switched with a button, so I can use a relay to switch the corresponding things. Switch trigger 100ms
I made a fine code with ESP-Home… in addition, a small automation so that when I switch it on, the device makes the desired settings directly
So far it works fine.
but…
What I would like to have in HA is that the ESP recognizes that the air conditioning is also on… maybe. tap the voltage from the power LED and use it as a status.
how can i this realized?
big thanks
