Contoller board for up to 10 floor heading circuits. Thermostats via MQTT or 868MHz RF (to be developed). Changed from 1-Wire to 868MHz connectivity in version 2.0.
Central controller for my floor heating based on the ESP32.
- Wifi (MQTT implemented) and BTLE (currently unused) from ESP32.
- AES encrypted and optionaly ATSHA204 authenticated 868MHz radio (to be implemented).
- 10 low-side switched outputs that can be individually controlled and output the input voltage. (Speed limited by the shift registers. Hardware SPI theoretically possible but untested.) Used to power valves.
- 4 Qwiic-compatible I2C ports
- 1 ~7.5V/5V/3.3V/GND ports for powering thermostats.
- JTAG header
Can be mounted in small breaker boxes on DIN rails. Display fits into the opening for breakers.
