Hi folks, Continuing the discussion from New smart wifi radiator valves from Shelly Thought it would never happen again, but finally I have ordered a Shelly TRV to experiment. But not quite sure what is the best way to control it. For my other Shelly devices (mostly plug-S) I use MQTT instead of…

[image] Buckskin: From looking at the documentation I think ext_t.enabled bool If temperature correction from external temp sensor is enabled that you can use an external temperature sensor as a control if you wish Yes indeed that was what I was also thinking the first time I read that …

[image] BartButenaers: So it is to measure the temperature inside your room, not outdoors.. But this can be manipulated in Node-red using both internal & external sensors because all the valve is after is a temperature, source is irrelevant. I haven't though through how this can happen but w…

Just a suggestion: did you consider to drop shelly an email with your findings instead ?

[image] Buckskin: But this can be manipulated in Node-red using both internal & external sensors Yes indeed that might be an option. But I had hoped the Shellies could do this out of the box. They are not really cheap after all... Talking about this, I think I have misinterpreted the "desi…

I put together a very over-the-top flow (based on something totallyInformation said) and get this graph for each of my TRV's. The data is sent by the TRV, and sensor, not requested, when they feel like it (about every 1/2 an hour). The position line is the actual open position of the valve (between…

[image] Buckskin: not only does the TRV need to be trained but so does your boiler. If you do come up with something I bet there are bunches of people who would be interested. Don't want to too much off topic here, but you might ask your question in this discussion.

ext_t.enabled is indeed a temperature sensor external to the Shelly TRV. I use a room sensor I have built from an ESP8266, but of course, as long as the Shelly can see the temperature on the Network, it doesn't care where it comes from. The Profile/Schedule event shows what the desired temperature…

[image] mudwalker: never liked measuring temperature at the point of a heat source, they cross talk too much I see that they also offer an offset setting: TEMPERATURE OFFSET There are two options you can tick to activate - Enable external temperature corrections endpoint http://192.168.207…

There is an article on auto-calibration of TRVs here Your TRV is lying to you: TRV auto-calibration - NotEnoughTech While the TRVs and sensors used are zigbee the concept and ideas are still relevant and could be re-done for the Shellys with no bother. I started looking at this because the TRVs us…

Sorry, I am following this thread but we have family visiting so computer time is limited. Yes, I have seen the offset, but whichever way I do things, I am required to interrogate or update the TRV on a regular basis for the current temperature status. My idea is to only communicate with the TRV w…
