Heatmiser Thermostat

The 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 Wifi, but the HeatmiserV3 python module being used is a full implementation of the V3 protocol. If you would like to contribute to making this work over wifi, please contact @andylockran on github.

To set it up, add the following information to your configuration.yaml file:

  platform: heatmiser
  ipaddress: YOUR_IPADDRESS
  port:  YOUR_PORT
    - 1:

A single interface can handle up to 32 connected devices.

Configuration variables:

  • ipaddress (Required): The ip address of your interface.
  • port (Required): The port that the interface is listening on.
  • tstats (Required): A list of thermostats activated on the gateway.
  • id (Required): The id of the thermostat as configured on the device itself
  • name (Required): A friendly name for the thermostat
