Error fetching shelly 1 plus

Hi,I have a problem with my shelly 1 plus: Error fetching Porte data: Device disconnected: DeviceConnectionError() despite that I apply this: ws:// in setting shelly.
How can I solve this pb please?

Try connection type: TLS no validation

no succes and it’s worse:

You use shelly too?

Sorry for the delay - yes, I have 10 shelly devices (Uni & plus1pm) and I don’t have this problem. Are you running the latest firmware? What is the wifi connection strength (rssi value)?
