  • Adapter ring for older TVR valves (M28 to M30)

    Hi Bemo47,

    I found these adapters, but the problem I have is that they stick out even more. The Shelly TRV already sticks out a lot. With the adapter it is even more. The ring actually takes up less space. Also, I'll probably need a lot more TRV's and if I print them myself it's a lot cheaper.

    I actually run in quite some issues with the Shelly TRV and they work very unreliable even with the Shelly App. Integration in Home Assistant is not working at all. What is your experience with it?

  • Adapter ring for older TVR valves (M28 to M30)

    Hi,

    I ordered 4 Shelly TRV's to replace some older manual TRV's. It turned out the the adapter rings that are delivers by Shelly did not fit. In stead of helping me to resolve the problem, Shelly simply told me to return the TRV's on my own expense. This frustrated me as a simple converter ring from M30-1,5mm to M28-1,5mm would resolve the problem.

    So please find attached some 3D files to print an adaptor ring. I hope this might help you should you have a similar issue.

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

    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.

    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?
