Errors operating Xiaomi Gateway

Add-ons Bindings

I have followed the tutorial to configure Xiaomi Bridge with Gateway. My things configuration looks like this:

Bridge mihome:bridge:34ce00fbxxxx "Xiaomi Bridge" @ "Ground Floor"[ serialNumber="34ce00fbxxxx", ipAddress="172.17.xx.xx", port=9898, key="xxx", pollingInterval=300 ] {
        Things:
                gateway 34ce00fbxxxx    "Xiaomi Gateway"        @       "Ground Floor"  [itemId="34ce00fbxxxx"]

                sensor_weather_v1       158d0001b9xxxx  "Xiaomi Temperature Sensor"     @       "Ground Floor"  [itemId="158d0001b9xxxx"]
}

Please note, I had to modify the things file as compared to the tutorial, because in OpenHAB 2.2.0 I was getting an error:

Provide a thing type ID and a thing ID in this format:
 <thingTypeId> <thingId>

And now comes my problem. The gateway, bridge and temperature sensor are all visible and online in PaperUI. However, when I try to change any parameter in Control in PaperUI, in opehab.log I get:

Can you help me to solve it?

I’m just now also working through my new Xiaomi gadgets! :wink:

I avoid declaring anything via PaperUI (the old-fashioned file-based guy as I am). So, I do have this setup:

xiaomi.things

}

Hope that helps…

At the moment I get information from the weather_v1 sensor and I got the switch and the motion sensor running in my test environment. I didn’t manage the smoke detector. On my designated live environment I managed (with the same configuration) to get the weather sensor live. But I guess, it’s Hardware related, because that one is (for now) on a Pi1, and I guess that one simply isn’t strong enough (ist at 100% CPU since I installed the binding).

A question: What’s “pollingInterval” stand for? seconds or milliseconds?

Looks like you are having the same issue as reported here:
