This is a BrewPi-ESP8266 temperature controller in a 3D-printed case. This works well and has been controlling my Keezer's temperature for the past several years.
This build is based around my older PCB design which uses RJ-11 (phone) cables for temperature sensors rather than RJ-45 (ethernet). This also only comes with a single temperature sensor -- you will need an additional sensor if you ever want to use beer constant/profile mode.
Offered for free, but you pay shipping which I'm guessing is somewhere between $8-12.
