My zwave sensor is approx. 2.5 degrees off (too high). I’d like to set an offset, but the parameter does not seem to work. If I set it to 0, 2 or 5 (integer) the temperature I get remains unchanged. I use HABMIN 1.9 (latest build). After I change the parameter I force a wake up so the parameter changes from yellow to white.
I did some additional testing. I changed the parameter to 200 and expected a rise with 200 degrees celcius. It appeared to be 20 degrees. So an increase of 1 means an offset of .1 degrees. I was able to set the parameter to -25 and now temperatures are in line with other temperature sensors around the room. Case closed.
@chris I will update the zwave database with this documentation soon.
