I am sure it could be, but not at that quality unless you ready to invest into teaching them and ironing out the kinks untill you get your product. Itwould be basically a copy of this or something similar. With cheaper parts, less features and half ass quality. Like all knockoffs are. They have the cheap manufacturing, but not the bright minds or practice to get to quality products on their own most times.

I wont start producing circuits, just thought of looking for readymade ones already sold

Otherwise, ill go with the normal on off thermostat...

I've used Lux programmable thermostat outlets for decades. inkbird and a few others are in the game now, but Lux are rock solid performers. They will turn the fan on and off according to the temp settings you input. Dimming would need to be done with another device.

Hoping someone has info on a dual controller of sorts.

FWIW Lux WIN100 would be the item.
Good solid performer basic programmable Tstat with adjustable hysteresis capable of switching a small AC reliably for years.
