Shelly TRV Alternative?

Add-ons Bindings
1

Hey all,

Shelly TRV Thermostat is discontinue. So I cannot order them.
Is there an Alternative product on the market, which works in the same way?
It should be supported by an OH Binding. So not via MQTT. Any ideas?

The Bosch one is zigbee! Looks good but it’s pretty expensive. But might be good to confirm that the zigbee binding is compatible with it.

Otherwise you have a lot of options in the AliExpress / zigbee space.

They might be back end of the year…

I bought a lot of them ( tuyas, moes…) on my quest for the perfect solution. Result:

  • mechanically bad quality (plastic notches breaking…)
  • not working with rechargeable batteries
  • very unprecise (no adjustment although 2 degrees difference to target temperature)
  • very loud

I didn’t try Shelly first because I was afraid of short battery life due to the wifi connection. But after all the failures I finally gave Shelly a chance. Result:

  • rechargeable (e.g. with a power bank)
  • good battery life
  • lots of options for configuration
  • The web-ui needs many reloads to come up (up to 10x), but that’s not a problem during normal usage.

I bought a bunch of them from eBay and until now I’m quite happy with them (but it’s summer :wink:)

Have 11 Shelly TRVs in the house for over a year now and am really happy with the quality….

And that’s why I started of with the Bosch :stuck_out_tongue: I kind of expect things to be at least of decent quality there :smiley:

I’m curious about your experience (just in case Shelly is a dead end in case of discontinuation), so please share…
I read Bosch don’t work with rechargeables which is a no-go for me. Can you confirm that?

Huh? Where did that come from?
The only difference is that the rechargeable batteries have lower nominal voltage (1.2v vs 1.5v). Which is borderline irrelevant since voltage fluctuates as charge goes down anyway…
This makes no sense.

but I went to check the manual and this is their specification:
Batteries 2 Ă— LR6/Mignon/AA
(alkaline)

Battery lifespan
(typical)
< 2 years

I also checked online and found no remarks about they not being compatible so I really doubt that is a problem.

I have DECT Thermostats which also officially do not support rechargeable batteries.I tried rechargeables, and they work, but there are two issues which lead me to use alkaline batteries again

  1. Lower Voltage = higher Amps for opening/closing the valve. Which also means that the promised lifespan (e.g. 2 years) is not met
  2. Lower voltage also means that the thermostat “thinks” that the battery is almost depleted. And when you monitor the battery charges, then is gets really annoying seeing a lot of “low battery” warnings just because the devices run on rechargeable batteries
10

Both make sense and I see the possibility of it becoming an issue (thank you for the great answer!!). But then it would affect all devices with motors on them basically.

Well it surely makes sense cause electronic components might need the full voltage of alkaline batteries. It’s more common with older devices but occasionally new devices are not specified for the lower nominal voltage.
Almost all zigbee TRVs that I tried didn’t work well with rechargeables: Very short battery life or didn’t work at all.
In the Amazon reviews of the Bosch trv there are complains that they don’t work well with rechargeables.

At the shelly.com shop you cannot by it anymore, and it is located in the “discountinue group”.

Not more order at shelly.com is still for more that 3/4 year, but the information from @hmerk is interesting. Let’s see what happens in the begin of 2025…

My TRV works. A new technologie e.g. for DECT or Zigbee protocol in a new product is NOT an option for me, because in each case I need at least one new “gateway” for each floor (4x in my case). WLAN/WiFi I have already everywere… I also need the charge the TRV once a year before the winter starts, and that’s fine… But an replace LiPo batterypack would be be nice, perhaps in a TRV 2.0

Not entirely true, but I won’t waste your time if your already set in your thoughts :slight_smile:
