I just started with Openhab2. I have in use three Raspberry Pi in my network:
The first runs with openhabian as a switchboard
The second I use to control my glass house and the third is for other controls in my house.
My problem is this:
I use some ds18b20 an one dht22 in my glass house. The transmission of the temperature values of the dht22 to the BasicUI is OK,
but not those from the ds18b20. It seems, that the mosquitto server works, because I get the values with the MQTT Dashboard.
Also the Publishing the raspberry’s and one ESP32 is OK.
Here are my Items:
Number TempGewDHT “Temperatur GewDHT [%.1f °C]” {mqtt="<[mosquitto:garten/gew/dht-temp:state:default]"}
Number TempKelPumpe “Temperatur Pumpenkammer [%.1f °C]” {mqtt="<[mosquitto:keller/pumpe/temp:state:default]"}
Number TempKelWerk “Temperatur Werkstätte [%.1f °C]” {mqtt="<[mosquitto:keller/werkst/temp:state:default]"}
Number TempAussen “Aussentemperatur [%.1f °C]” {mqtt="<[mosquitto:garten/aussen/temp:state:default]"}

I am a bit confused.
Which items are updated correctly and which are not?
Can you make a list. Just the name of the items. We already have the definitions.
Thanks
