Sonoff TRVZB devices with the edge driver cannot be paired with an external temperature sensor

[DanielePinna (Daniele)]

@Mariano_Colmenarejo buongiorno, ho abbinato le mie TRVZB SONOFF con il tuo driver edge ma non ho possibilità di usare un sensore di temperatura esterno al posto del suo interno.

Il suo sensore interno è sfalsato in quanto appena il termosifone scalda raggiunge subito la temperatura da me impostata per la stanza e la valvola si chiude lasciandomi la stanza fredda,

E’ possibile integrare tale funzionalità, già predisposta per il sistema Sonoff, anche nei driver edge?

Grazie anticipatamente.

Hi, @DanielePinna

Welcome to the SmartThings Community!
People from different countries participate in this forum, so to allow others who might find this topic helpful understand this conversation and also for Mariano, we kindly ask you to provide an English version. What I could see using the translator is the following:

@Mariano_Colmenarejo Good morning, I have paired my SONOFF TRVZB valves with your edge driver, but I don’t have the option to use an external temperature sensor instead of the internal one.

The internal sensor is inaccurate because as soon as the radiator heats up, it immediately reaches the temperature I set for the room, and the valve closes, leaving the room cold.

Is it possible to integrate this functionality, which is already available in the Sonoff system, into the edge drivers?

Thank you in advance.

Please confirm if it’s correct.

Hello @Mariano_Colmenarejo ,

I see they never have been an answer to this question.
I’m looking for something like this as well. Any chance to make it work?

Also I was wondering if the driver could possess an offset setting?
(So we can set the offset a few degree above)

Find out if you can make it work in their own ecosystem/plattform/app.

@Mariano_Colmenarejo ,

The SONOFF ecosystem works perfectly with eWeLink, including pairing external SONOFF SNZB-02P sensors.

In my case, I already have an Aeotec hub and all my devices are fully compatible with the SONOFF ecosystem. I wanted to integrate the TRZB thermostatic radiator valves into SmartThings as well, without having to reconfigure everything in eWeLink.

Unfortunately, I couldn’t find a proper solution, so I had to work around the issue by creating automations (scenes) between the TRZB valves and the SNZB-02P sensors.

What I find really frustrating is that there doesn’t seem to be a SmartThings driver available that supports the TRZB valves with their full range of features. It’s hard to understand why such a driver still doesn’t exist.

We were hoping for a little magic from @Mariano_Colmenarejo!

so I had to work around the issue by creating automations (scenes) between the TRZB valves and the SNZB-02P sensors.

The problem is that this needs to happen in real-time. Other solutions allow direct binding between the sensors (temperature and window contact), so the internal algorithm of the TRV has it’s input.

Half a year ago I bought one of these TRZB to work on a driver for it, but I had other things to do - like about the a dozen of SmartThings drivers…

There isn’t much we can do to make it work. Binding is difficult, sometimes impossible, because these devices often have their quirks.

I’m using Kasa KE100 TRVs that are easy to bind to Tapo T310 temperature sensors and Tapo T110 contact sensors. It’s rock solid, works perfectly fine since years.

Thanks for the explanation! Had I known this beforehand, I probably wouldn’t have bought nine TRZB valves and nine SNZB-02P sensors. I would have opted for a more compatible and reliable solution, like the Kasa KE100 setup you mentioned.

For now, though, considering the money I’ve already invested, I’ve had to make do with SmartThings scenes to connect the TRZB valves to the SNZB-02P temperature sensors.

It’s a shame, because I would have preferred a proper, reliable integration rather than having to work around these limitations.
