NPKPHCTH-S probe

Hey everyone,

I’ve been working on a little project to monitor soil nutrients, pH, moisture, and temperature using an ESP32 and the NPKPHCTH-S probe. It’s all set up with ESPHome and supports different plant profiles with real-time sensor data on a touchscreen.

I thought it might be cool to share in case anyone’s interested or working on something similar. You can check out the code and setup on my GitHub: GitHub Repository.

Feel free to take a look, use it, and let me know if you’ve got any feedback or ideas for improvements.

Cheers!

I stumbled across your post as I was trying to figure out how to connect my RS485 soil sensors to an ESP32/ESPHome and have the information visible in Home Assistant.

Did you add the modbus integration to your configuration.yaml file for Home Assistant in addition to the ESP device code?
