Here is the testing on the overall framework:
Small issue while connecting the wires, took us some time to solve it, but nothing major. (Ports matching problem, and wiring problem)
Every single function we wanted works:
Fan ✅
Heater ✅
Purifier ✅
UV lights ✅
Humidifier ✅
Dehumidifier ✅
Turn it on at the same time : ✅
Turn on individually: ✅
Looking forward to the long term lab test results!
