Although i suspect not a lot of people will use this, i’ll share it anyway:
https://github.com/RedNax67/MMM-OpenTherm
For this to work you’ll need:
An OpenTherm controlled heating/cooling device An OpenTherm gateway http://otgw.tclcode.com/ The OpenTherm Monitor application running somewhere http://otgw.tclcode.com/otmonitor.html
NOTE: The otmonitor version hosted on the website doesn’t have the access-allow-origin-header so the browser running MM will probably reject the json response. Luckily the author also supplies the source and instructions on how to build/compile your own version.
I’ve compiled a (RpI) version of the otmonitor program with this header included. Anyone in need of if, please let me know.
The OpenTherm module displays:
- Current roomtemperature
- Room setpoint temperature
- Outside temperature
- Central heating pressure
- Heating on/of
- Hot water on/off
- Alerts (Low pressure)
-
Unfortunately can’t edit my FP…
Here’s a screenshot of teh module:

Why not use a
node_helper.js
to get around theaccess-allow-origin
policy?
