Conbee, aqara multi sensor temperature state invalid status

This is the json file:
“8”: {
“config”: {
“battery”: 100,
“offset”: 0,
“on”: true,
“reachable”: true
“ep”: 1,
“etag”: “d8e4cbfc09beb58d243002704be84a88”,
“manufacturername”: “LUMI”,
“modelid”: “”,
“name”: “Tuin Multi Sensor”,
“state”: {
“lastupdated”: “2020-02-12T20:46:39”,
“temperature”: 557
“swversion”: “20161129”,
“type”: “ZHATemperature”,
“uniqueid”: “00:15:8d:00:04:64:c8:5e-01-0402”

I get something like this in the log
2020-02-12 21:42:47.870 [WARN ] [rest.core.internal.item.ItemResource] - Received HTTP PUT request at ‘items/GV_Tuin_Multi_Sensor_Temperature_Temperature/state’ with an invalid status value ‘11,93 °C’.
2020-02-12 21:44:07.422 [ome.event.ItemUpdatedEvent] - Item ‘GV_Tuin_Multi_Sensor_Temperature_Temperature’ has been updated.

2020-02-12 21:46:39.200 [vent.ItemStateChangedEvent] - GV_Tuin_Multi_Sensor_Temperature_Temperature changed from 5.62 to 5.57 °C

I get an error in the openhab app (android) : http error 400…for that item

a few hours ago, I created a widget from the item, but deleted it afterwards.
Now, it’s like it still exists somewhere, because of the value 11,93 °C
In the sitemap, the temperature is correct. So, the error doesn’t affect the sitemap.
it’s strange there’s a comma in the value , while everywhere a see a point.
Maybe it’s getting there because of android.
anyone has the same error? How to get rid of it?
in the sitemap i have :
Text item=GV_Tuin_Multi_Sensor_Temperature_Temperature icon=“Temperature” label=“Temperature [%.2f %unit%]”

Probably just change that to


I have cleared tge cache of the app.
And for now, it didn’t appear again.
I have 5 sensors, the other 4 had no problem.
