Adding Shelly Devices

I have 5 Shelly devices in HA currently. They are all working fine. I added a Shelly H&T. I have it set up in the Shelly app and it is working fine, but it is not showing up in HA. Is there a way to make the integration scan the network for new devices? Auto discovery is enabled and worked fine when I added the first Shelly’s.

Is you shelly HT battery powered?
If yes it communicates only when woken up (a few minutes when woken manually or a few secs if woken up by temp/hum change)

What does it mean it is no showing up? does it report unavailable state or indeed is missing at all?

What integration do you use: ShellyForHass or mqtt.

I am using Shelly for Hass. It is not being discovered at all. And yes it is battery powered. It is available in the Shelly app, and a test alert was triggered today to see if that would enable it to be discovered.
