heatmiser climate platform let you control Heatmiser DT/DT-E/PRT/PRT-E thermostats from Heatmiser. The module itself is currently setup to work over a RS232 -> RS485 converter, therefore it connects over IP.
Further work would be required to get this setup to connect over Wi-Fi, but the HeatmiserV3 Python module being used is a full implementation of the V3 protocol.
To set it up, add the following information to your
climate: - platform: heatmiser host: YOUR_IP_ADDRESS port: YOUR_PORT tstats: - id: THERMOSTAT_ID name: THERMOSTAT_NAME
A single interface can handle up to 32 connected devices.
