Hmm, just to let you know… I did some digging into this matter. And I actually managed to receive the issue here. It´s highly strange indeed.
I asked (by voice) google to change the temperature in my office (where I´m sitting right now). Google respond with the same frase and issue you´re having “unable to connect to openhab”. But the temperature (setpoint) did indeed change:
2019-10-30 22:15:58.123 [ome.event.ItemCommandEvent] - Item 'kontor_Tempsetpunkt' received command 22
2019-10-30 22:15:58.433 [vent.ItemStateChangedEvent] - kontor_Tempsetpunkt changed from 21.00 to 22.00
I then asked google to turn off the light at the office. Google responded with “okay turning of the light” and the light turned off.
The I asked Google to turn on the light, Then I recived a “pling”" which means it has done it cause the GH mini is placed rigth next to me in the office. And the light turned on…
I repeated this several times. No issues.
I then tried the temperatur (setpoint) change again… And again I receive the respond “unable to connect to openhab”, but the temperature (setpoint) did indeed change again, just fine.
2019-10-30 22:21:50.491 [ome.event.ItemCommandEvent] - Item 'kontor_Tempsetpunkt' received command 21
2019-10-30 22:21:50.774 [vent.ItemStateChangedEvent] - kontor_Tempsetpunkt changed from 22.00 to 21.00
So right now it seems, I have no issue with “Ligthing” and Switchable tags. But “TargetTemperature” seems to be an issue, for me.
I then asked Google about the temperature ( “CurrentTemperature” tag). It worked, BUT! It gives a very strange result, as “she” gives me three temperature values.
One for the actual temperature,
Second for the actual setpoint,
The third value I have no idea where this came from. She said 24 degree celcius. And it doesnt make any sense.
I grapped my phone and copied the text from my activity… (this is a good tip to use when having problems).
This is the fully respond I´d get: (translated into english)
“The heating is set to 21 degrees at the Office Thermostat with a current temperature of 23.5 degrees.
Right now there are 24 degrees.”
The last one, 24 degrees makes no sense at all. I fail to see how its even possible to respond with three temperature values.
So, it seem there are some very weird things (still) going on around the thermostat and temperature… Strange enough, this is also the issue I have filed about using the Google Nest Hub. I dont use temperature or thermostat changes alot, which may be the reason why I havn´t noticed this untill I did these tests today.
