Shelly - Support for Shelly Pro 3

I’m running HA 2023.9.3 with all the latest updates but this unit will not show up in my device list. I have several other shelly devices that works just fine, including a Pro 4PM, which is the device this unit is the closest to.
I have double and triple checked settings for MQTT to no avail… it will not show up in HA…
The device in question is:

Do you got the Pro 3 integrated?

I am looking to buy one, but would need to get it working with HA

Thanks is advance for any information

Dear all!

I have kind of the same integration problem with the same device. HA finds it easily but can’t integrate it.

Any advice to config the websocket according to the shelly documentation has no effect.

Thanks for your help in advance!
