I use an ADS1115 chip to read the values of my capacitive soil moisture sensors, I noticed you have: ads.setGain(GAIN_ONE); which means the ADS1115 will read a value +/- 4.096V. Then you have: voltage = ads.readADC_SingleEnded(0) / 10; which takes the voltage and divides by 10, so now you will only...

how do you send the calibration messages to the device from home assistant? An automation to send a message over MQTT? Also, I spent a chunk of my weekend and have essentially rebuilt the framework into ESPhome. The one part I can't figure out and maybe you can help me is this: voltage = ads.readADC...

When you set this all up. did you ever try adding a custom component or did you configure through esphome at all? Trying to figure out a way to do this all through ESP home

What pumps did you end up using for this? I don't want to buy a bunch of individual pumps if i don't have to
