Welcome
First could you use the code fences when post code, please?

If you define the label in your item definition, you don’t need a label parameter in the sitemap, it will override it.

Number:Dimensionless Therm_UP_Hum “Humidity [%d %%]” { channel=“nest:thermostat:703015b1:-mq40LgwUjWvXUweq-yQLyQOVHNvWqeU:humidity” }
