TRV 's seem to have very poor reception and looses connection all the time.

Hi,

I run into major issues with the Wifi connection of all my TRV's (4). In locations where I have rather good Wifi signal (-60dBm or better), the Shelly app looses connection all the time and the devices gets offline. Also in the browser I can not reach the TRV's. The Wifi signal is OK as my mobile and 2 other devices (Sonoff) on the same AP work perfectly. Also the TRV's report device signal as "Good". The AP is about 5 meters away from the TRV's. This is a very frustrating experience for me. I wonder if anyone has experiences similar problems?

Raboof,

Thanks for the reply. In my case, it is very intermittent. Particular with one TRV, I loose connection all the time. The others seem to be a bit more stable but not workable. I have integrated them with Home Assistant integration the and HA reports the following in the log:

• Error fetching Badkamer TRV2 data: Sleeping device did not update within 3600 seconds interval
• Error fetching Badkamer TRV1 data: Sleeping device did not update within 3600 seconds interval
• Setting state for entity Badkamer TRV2 failed, state: {'target_t_enabled': 1, 'target_t': '24.0'}, error: TimeoutError()
• Setting state for entity Badkamer TRV1 failed, state: {'schedule': 1, 'schedule_profile': '4'}, error: ClientConnectorError(ConnectionKey(host='xx.xx.xx.xx', port=80, is_ssl=False, ssl=None, proxy=None, proxy_auth=None, proxy_headers_hash=7041496752766080900), OSError(113, "Connect call failed ('xx.xx.xx.xx', 80)"))

The one that always looses connection, is the one that I have put closest to the AP and has the best Wifi signal. So it must be something with the Wifi receiver. I noticed that the TRV's have network chips from Silicon Laboratories, not from Espressif Inc. (ESP32) like the other Shelly devices I have. I can not put a AP next to each TRV so I'm stuck.

It's an interesting point. I am assuming the TRV does not have a sufficient reception of the Wifi signal. You point out that the device could go in sleep mode and can not be waken up. I can check it by placing the AP next to one of the TRV's and see if the problem continues. To be continued.
