heatmiserv3
[!CAUTION] Unfortunately having lost access to the physical thermostats a few years ago, I can now no longer maintain this project.
If you fancy taking the maintenance off my hands, please get in touch and I'll setup an org to host the package, and migrate the pypi ownership to the org. Please see the ADRs in docs/adrs for decisions made since losing access to the physical thermostats.
This library has been created from the work carried out by Neil Trimboy in 2011 here: [https://code.google.com/p/heatmiser-monitor-control/]
The library uses the Heatmiser V3 Protocol to communicate with a number of thermostats
As the DCB Structures are different on each thermostat, this module doesn't yet cover all their intricacies, but with the connection in place, it provides a raw method of interfacing directly with the thermostat.
I hope to add specific model support as it gets requested.
Supported Thermostats
DT/DT-E/PRT/PRT-E/PRT-HW
Supported Timing Switches
The timing switches have a smaller DCB, but it is possible with this module to still send raw comamnds to them.
TM1/TM1-N
Other sensors
Heatmiser have used their V3 protocol in a number of sensors. Your mileage may vary in attempting to use this library to communicate with them, but please open a pull request if you get something working.
Requirements
Python needs to be version 3.10.
Package Management
I recently switched from poetry to uv.
Packaging and publishing
This library fell out of a little bit of love as I moved out of the home that had the thermostats. However, it appears to have quite a significant following on home-assistant, with a number of users wanting to benefit from it. I've therefore tried to improve the resilience by upgrading the packaging, building and publishing process to poetry. This should make the project easier to contribute to, and align with the latest standards in the python ecosystem.
