Will there be an update that the Blu TRV will also be compatible with Shellys 2PM Gen 2.

[Polof1]

Hello,

I'm a real Shelly fan and have already installed countless Shellys privately (and in the whole family and friends) and so I'm currently very disappointed.
I would like to share this with Shelly as a customer review and my question below.

My question:

I've waited a long time for the TRV successor and now this...
Will there be an update for the BLU TRV so that it can also be connected to GEN 2 Shellys (especially the 2PM Gen2)?

Because I and I think many other Shelly customers have installed them for roller shutters in every room. Otherwise I find the Blu TRV useless and not really smart.

So I will not buy it and if you search on the Internet in forums, others will not buy it either. For many people, the dongle is not a solution and they tend to go for other smart radiator valves. I think that is a commercial argument for the Shelly development, if you want to survive in the highly competitive market for smart radiator valves.

So far, a good idea, but poorly executed. I can't currently see any reason why it couldn't have been designed to be compatible.

I have the feeling that Shelly is losing its strengths such as being smart, simple and a good solution.

Regards

absolutely my opinion. That's a good and important question. I hope Shelly will answer and, above all, deliver. The current “solution” is not a good one and Shelly is not developing in a good direction from the user's point of view, in my opinion.

Somehow this is unfortunately a bit of a problem with the newer generation products.
If you look at the RGBW2, which is used in many environments with a 230V switch, no optocoupler or similar was supplied, as was the case with its predecessor.

I still think the Shellys are a great solution and I think there is something to come.

"I have the feeling that Shelly is losing its strengths such as being smart, simple and a good solution."

me too: the strength of shelly has been to be something that is usable even with a local programming, of from your local client, without having to resort to some closed source apps or worse to be forced to use a remote cloud app.

TRV is a "strange" device: all other shellies fall in one of two groups:
- switches that control a power user, so they all have a non constrained supply of power
- devices that sent information, that is the thermometers and the buttons. These ones have internal batteries and send information ony when they have, they do not require real time connection

The first group are real servers, that have to be on all the time since at any time a client can ask for information or send a command. the second one has not to receive commands and the update their information on a gateway when necessary.

TRV actually is something that naturally fit in the first group, since has to switch power [in term of an hot fluid] and return information. However since the hot fluid cannot be tapped to supply the wifi transceiver as in electrical switches, someone decided to make it as a second group, using BLE and connecting erratically.
For a normal use it could also even work, since for heating a delay of a few minutes in the command actuation is still acceptable.
But this means that the gateway must be "smarter" than the average shelly, since has to mirror the state of the peripheral and update two way it any time.
Something that it is not, expecially thinking that there are in the market many "non ‘smart’" devices that cost less than the shelly-BLU-TRV hand had a lot more local features.

I will return my 6 BLU TRVs until the devices can be connected via my shutter controls. Another dongle for every room?
Sorry, no.

Totally agree. Already open this topic:

It is a pain that the signal strength of the Gen3 Gateway is so weak, I have deployed 16 units on 4 floors, my Home assistant bluetooth can pick up all units even thou its in a ground floor data cabinet ( metal ) yet the Gen3 Gateway has trouble seeing the TRV next door
