eQ-3 thermostat with OpenHAB Smart Home

i am still trying to run the project.

i still think openhab doing wrong, cause the whole “comand” works

Number thermostat_wz "Thermostat Wohnzimmer [%.1f °C]"  { http="<[*:GET:http://192.168.178.35/eq/php/eq3.php?mac=00:1A:22:10:71:C8&temperature=25]>[thermostatWohnzimmer:60000:JSONPATH($.temperature)]" }

http.cfg
thermostatWohnzimmer.url=http://192.168.178.35/eq/php/eq3.php?mac=00:1A:22:10:71:C8{Authorization=Basic SECRET}
thermostatWohnzimmer.updateInterval=120000

in the log of openhab, there is no “refresh entry” to see.
I dont know, if openhab is sending a log entry after the code is getting refreshed.
but i think openhab is not sending the comand.

2019-12-22 14:13:37.159 [ome.event.ItemCommandEvent] - Item 'thermostat_wz' received command 20

2019-12-22 14:13:37.173 [vent.ItemStateChangedEvent] - thermostat_wz changed from 20.5 to 20

thats the only log entry i get, it looks “ok” for me but the thermostat doesnt react too it.
But the whole comand works, when i send it as “link” by the browser.
