M5Stack Atom Lite plant watering (Home Assistant / ESPHome)

After a lot of trial and error have set up a plant watering device that uses M5 Atom and watering kit, coded and managed by ESPHome and automated using Home Assistant.
Water sensor data, RGB LED and pump controlled via MQTT.more information and code here; https://github.com/rasclatt-dot-com/ESP32-Plant-Waterer-for-ESPHome

Thank you for this guidance. I have successfully setup this system, almost exactly, to water a single outdoor plant pot whilst I'm on vacation. I popped the electronics in an adapted waterproof project box. The only disadvantage is that the pot is quite deep so the moisture sensor doesn't go deep enough. The pump works great. However, I've learnt a lot from the experience.
