Temperature Offset for hue motion sensor

[Fish2]

Both of my hue motion sensor are reading around 2c lower than any other temp sensor I compare with is there a way you can add a temp offset and the I can run them throw this Homebridge plug in instead of native

I implemented an offset in deCONZ, which is exposed by Homebridge Hue. I cannot do the same for the Hue bridge, as it cannot store the offset between Homebridge restarts, see #492.

I find the the temperature sensor in the Hue motion sensor is not very accurate, and adding an offset only helps a little. Even after calibrating the sensor with an offset, so that it would correctly read 21°C, it would still be off at 15°C.

I think there’s a reason Signify don’t mention the temperature sensing feature in their marketing. I was actually surprised when the device turned out to include this. I think the device doesn’t actually contain a separate temperature sensor, but simply re-uses the infrared sensor for motion detection.

Ok thanks for getting back to me. so there no way for the plugin to read the temp that is send to it and then add a number to that temp from the plugins config file then re report it ? or how would I go about configuring the deCONZ offset ? cant see any pages in the wiki relating to thats

The offset in deCONZ is exposed as config.offset on the ZHATemperature /sensors resource. Homebridge Hue exposes it through a custom Offset characteristic on the Temperature Sensor service. Apple's Home app doesn't support custom characteristics, but you can set this from any decent HomeKit app.
