Using an ESP8266 ESP-01 module and an Arduino Pro Mini 3.3V I wirelessly update all outputs from my thermostat to here for data analysis and because it's cool.
This requires a voltage divided rectifier since thermostats run at least 24 VAC RMS.
Current sampling on electric kiln provides a 'signature' curve for each firing, enabling remote monitoring with minimal resources.
Platform: ESP32 (NodeMCU) w ADS1015.
Live only when firing in progress.
A NodeMCU with 3 DS18B20 monitors the temperatures (T[o, T[u]) of a storage tank, heated by a combination of oil boiler, wood boiler and solar panels, the temperature of the wood boiler (T[HV]), and the temperature of the exhaust gas (T[Ag].
