dominikamann/oekofen-pellematic-compact · vv4.4.3
Community integration for ÖkoFEN pellet heaters and heat pumps in Home Assistant via the official local JSON interface: automatic entity discovery, diagnostics and predictive warnings.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
climate | Thermostat | |
binary_sensor | Sensor (motion, contact, leak, smoke…) | |
sensor | Sensor (temperature, humidity, air quality…) | |
button | Button (as a switch) | |
select | Mode picker (as switches) |
What people report

| Ökofen Pellematic with US firmware 3.10 | Works Local | JSON read failure fixed in v4.3.1Saved copy… successfully for several years on older versions. I updated to the latest version (v4.2.10) yesterday, seeing the note on the page that it now supported boilers with older firmware.

Unfortunately, v4 seems unable to open and/or parse my boilers /all json file. When I use reconfigure in the integration, I double check that the json url is correct - it works in my browser.
