You may or may not have asked for it, but here is it anyway: Another smart thermostat using the Raspberry Pi Pico W. Still cheap, still secure.
Code for the Picostat V2:
github.com/SmarterCircuits/Picostat-V2
Code for the Home Assistant controlled relay board:
github.com/SmarterCircuits/HA_Pico-Relay-B
Parts:
Waveshare 8-relay pico board (no pico, $29):
amzn.to/3GUG0d0
Waveshare 8-relay pico board (with pico, $35 best deal in my opinion):
amzn.to/3RFJYeD
OLED I used, there are cheaper, smaller ones on the Waveshare store ($22):
amzn.to/4aCOF1A
Waveshare Store:
amzn.to/3NCUnXh
2-pack Raspberry Pi Pico W ($22):
amzn.to/488N55N
PINS:
OLED:
These just need jumped to the location they would be if it was directly plugges in, but without the I2C pins because we don't use them and they would conflict with the RGB LED on the relay board.
