Robust roller shutter relays

I’m currently using some Shelly 2 and 2.5 to control my rollershutters. Unfortunately after only 2 to 3 years they start dying. (Broken capacitor, seems to be quite common, at least for the Shelly 2.5). In addition I’ve had trouble with some of them as they disconnected from the wifi and never came back without a reset.
Now I’m looking for alternatives. I could go with the Shelly Plus 2PM, hoping they fixed the quality issues. But that would probably still leave the connections issues. And I don’t want to add additional Wifi hotspots, the 2.4Ghz bands are already crowded enough around here. On the plus side: even if support is dropped for the Shellys I could flash tasmota.
Another option seems to be Z-Wave. Something like Fibaro Roller Shutter 3 is hopefully build for a bit longer lifetime. But Z-Wave seems to be pretty complicated. I have a Z-Wave stick and a FGR222 from earlier test before I bought the shellies and couldn’t get it to work. Bridge and device were both online but the FGR222 just wouldn’t react to commands and the log was flooded with messages (in debug mode). Maybe a solvable issue but not the most encouraging result :slight_smile:
I’ve also seen some enocean devices e.g. from Eltako which is at least a company I would trust to make save devices, which is not neglectable for something connected to 230V 24/7 imho. But I know nothing about enocean. I think it does not mesh, so maybe I could also run into trouble with connectivity.
Anything else I missed which has no vendor lock-in and works for 10 years without having to think about it?

In debug mode the zwave binding is always going to generate a lot of logs.

Is this device battery powered? If so you have to wake it up to give the binding a chance to interrogate it and figure out what it is.

If it’s a new device it may not have been added to the database yet.

If the binding was able to recognize it, it might not have a good wireless connection to the device. Zwave is a mesh network. The more mains powered devices act as relays. If you’ve only one device, it needs to be pretty close to the controller.

I think my post was a bit confusing. I’m not so much interested in solving that Zwave issue, it was more of an experiment to see how complicated Zwave is. What I actually wanted was to hear some experiences of other people what roller shutter relays work reliably for a long time?
Regarding Zwave range: what is “pretty close to the controller”. I would probably put the controller in the middle of the house where an openwrt device is sitting and forward via ser2net to my openhab machine in the basement. That would mean about 6-8m to the nearest device. Is that too far? And does Zwave have problems with two devices just a few centimeters apart?

As with all wireless technologies it depends. In an ideal environment (which doesn’t exist in nature) it should reach 100m. But throw in one cinderblock wall or a wall with a lot of copper in it or something and the range may be significantly less. Not all devices transmit at full power also so range is :person_shrugging: It should be fine in the same room.

For the most part, the quality of a Zwave network depends on the number of mains powered devices more than range. But YMMV.

I’d argue that it’s not more complicated but harder to debug.
You have to learn all the Z-Wave wording, what it does and then always use the dongle to communicated with the device. For Wifi you already know all that.
And while battery powered devices can be a pain to set main powered devices are usually pretty straight forward. Move them to the controller, put controller in inclusion mode, power up. That’s easier than assigning a wifi to a shelly device.

Normally the next room should always be fine without issues.

I have my z-wave stick in the basement and from there it reaches three other mains powered devices from the floor above. That’s enough to have the network reliably route all the messages from throughout the house to the controller.

I have one Fibaro FGR222 which runs without issues since 5+ years.
From my Shelly 2.5 six or seven are already dead. I just hope the newer ones have better quality.
