Opentherm to Modbus gateway module allowing control of OpenTherm boiler with UniPi v 1.1 and UniPi Neuron control units.
Opentherm to Modbus gateway module allowing control of OpenTherm boiler with UniPi 1.1, UniPi Neuron and UniPi Axon controllers. The module is a gateway for linking systems with Modbus RTU RS485 (EIA-485) communication and boilers with Opentherm+ (OT+) and thermostats. It allows to either monitor data flow between thermostat and boiler or to control the boiler directly. We recommend connecting this module to UniPi v 1.1 via USB-RS485 Convertor.
- Monitor: module is only monitoring communication between boiler and thermostat
- Controller: in this mode, it is also possible to control the parameters of the boiler by writing to Modbus registers
