I have a BioPod (https://www.biopod.com/), but the company is pretty much going under, so the controller app is probably going to stop working and support doesn't really exist. I have decided to try and rebuild the functionality myself with a NodeMCU, relays, MQTT and home assistant.
Could someone take a look at my sketch below and see if it seems sensible. I am pretty new, it is 1/2 built but want my approach sanity checked.
Ability to turn all devices on/off as needed
Dim LED lights.
External components are:
1 low pressure want pump
1 high pressure water pump
1 air pump
1 heating cable
1 temperature monitor under water
1 humidity and temperature monitor
