The sensors seem to work reliably:
There is a bug in the device firmware which leads to negative luminance values (see Negative lux value).
Workaround:
- Install the JS Transformation Service.
- Place signedWord2unsignedWord.js.txt (168 Bytes) in conf/transform (remove the ‘.txt’).
- Add the transformation to the Item as a Profile :
If it doesn’t work, use
log:set debug org.openhab.transform.javascript
and
log:display | grep orma
to check what the JS Transformation is doing.
Edit:
Result with fix in place:
