change it this way, and even ungroup this item
but not showing anything
Chart item=esp_dht22_t period=1h refresh=10000
The timeframe should read “h” instead of 1h.
Have you installed more persistence services in this case you need to state the service in the sitemap as well .

Good Morning.
thanks, can I use other services for charting? what is your suggestion?
Do you have other sitemap files in the sitemap Directory?

No more suggestions from me, I’m sorry.
