You can choose from several ready-made adapters or roll your own: This component acts only as an OpenTherm master (for example, a thermostat or controller) and not as a slave or gateway. . Since OpenTherm doesn’t operate in a standard voltage range, special hardware is required. 3V controllers like Arduino, ESP8266 or Raspberry Pi. This adapter is designed to connect an OpenTherm compatible boiler to any TTL port (TTL-USB, ESP8266, ESP32, Arduino, etc). Same size as popular RS485-TTL module for more compatibility. Mar 12, 2024 · OpenTherm transmits data to the boiler using voltage levels, and receives data from the boiler using current levels. Apr 2, 2018 · OpenTherm Adapter is minimized version of Arduino Controller and its compatible with 5V and 3. Description Specs Shipping Volume Pricing OpenTherm protocol requires simple low voltage twowire connection to boiler, but voltage levels (7. This version of library uses interrupts to achieve better stability and synchronization with boiler. 15V) still much higher than Arduino/ESP8266 levels, which requires OpenTherm Adapter. 3v.
