I wanted to make my own thermostat, so I used a nodeMCU, ds18b20, and a relay pack to make one with a web interface. Then I got distracted for a bit and did nothing for almost a year.

Then the relay pack stopped working reliably, so I got a KC868-A6 and ported the existing code to it. Then I added Modbus functionality to it. This is being tuned.

Next step is to rework my old unfinished thermostat code I wrote for a Seeduino Wio Terminal and make it work with the controller...as of 16th December, 2025.
