TRV does not get room temperature from Shelly H&T G3

Hi,

Just bought two TRVs and a Shelly H&T G3.

All linked to my WiFi and with fixed IPs.

Firmware, the latest as of today.

Firmware TRV: 20231122-131839/v2.2.2@a458c94d and downgrading to 20220811-152343/v2.1.8@5afc928c did not help either.

Firmware H&T: 20240213-140437/1.2.0-gb1b9aa8

Set the TRV to get info from webhook:

I then set the outbound webhook in the H&T:

Can see it sends the info, but it is not received by the TRV. The IP is correct, and I have tried different suggestions for the "temp=" parameter, which I trust is the issue?

A websocket debug from the H&T is shown below:

"ts": 1707905685.525,

"level": 2,

"data": "shelly_http_client.:306 0x3fcc34f8: WS http://192.168.1.51/ext_t?temp=%24%7Bev.tC"

},

{

"ts": 1707905687.633,

"level": 2,

"data": "shelly_http_client.:606 0x3fcc34f8: Finished; bytes 126, code 200, redir 0/3, auth 0, status -19: Invalid WebSocket handshake response"

I would like the H&T temperature to be the input to both TRVs, but do not see how to make two outbound addresses in the websocket setting?

Please tell a Shelly beginner what to do.

Kind regards

Henrik

Hi Guys

Anyone proficient in websocket, pleaset? Or am I doing anything else wrong?

The TRV says:

Why is "measured t" in blue?

What should I paste to the Shelly H&T G3 outgoing websocket?

does not work......

Please, please advice me how to get it working!

Henrik

Got an answer today from Sofia Tech Support, which works for me:

Unfortunately, at the moment the Shelly H&T Gen 3 doesn't have its Actions available. You need to setup the external thermost via Actions.

We sincerely apologise for the inconvenience caused! The feature will become available soon!

As an example, we have provided you with pictures on how to set up an external thermostat with the Shelly Plus H&T:

The parameter after the '=' sign is whether the temperature will be in °C or °F.

We hope we were of help and remain at your disposal!

Best Regards,

Shelly Support Team
