My dad had picked up a new thermostat complaining about the old one not being sensitive enough or not being accurate, It appeared to not be able to turn the second heating coil on, maybe it only had 1 relay? Anyway i thought for that price i can do it myself, well i decided to modify it:* That is a raspberry pi 0 v1, so no built in wifi or camera plug
at 1st i had a A+ pi in there, before the pi0 was released and i needed more space to make the front panel
there are 2 things i am not happy with and both are the power supply, that blue LED is well insanely bright (visible through the face plate) and the coil wine
I would guess i am pulling under 300ma at any given time (100ma board + wifi + a single relay)
*Programed/designed so that both relays will never have there coil powered up at the same time
*the lcd is so low power it should be under 0.025ma
at least that supply has never let me down in the few years i have used it
