Temperature visualisation in OpenHab2

I have a problem with visualization of temperature in OpenHab2.
I send data from Arduino sensor through mqtt it is already posted on mqqt broker on PI3. But there is nothing in Basic UI.
files as follow:

Switch Switch1 {mqtt=">[mosquitto:home/lights/in:command:ON:1],>[mosquitto:home/lights/in:command:OFF:0],<[mosquitto:home/lights/in:state:ON:1],<[mosquitto:home/lights/in:state:OFF:0]"}

Number Temperature “Temperature [%.1f °C]” {mqqt=">[mosquitto:openhab/himitsu/temperature]"}

sitemap home label=“MyHouse”
Frame label=“Light Switch”
Switch item=Switch1
Text item=Temperature


Switch is working well so just i have a problem with number. This only displays " -°C" Please advice

You have multiple errors in your item configuration. Please have a look at the examples here:


The first example under the heading “Example Inbound Configurations” should be what you are looking for.
