Bad connection to Namron z-wave dimmer?

So i had a bad time including a new Namron 3 wire dimmer the other day. Homey found the dimmer and i could do the inclusion, but when it went forward to add the device it errored out.

The Homey and the dimmer was standing 5-6m away from each other inside my living room with a clear line of sight to each other(no walls, furnitute, or other objects) so i didn’t think it was a reception / signal issue. But i finally moved the Homey up right beside the dimmer and tried just for the giggles, and it worked?!

Well ok now that it was included i moved the Homey back to where it was again, and now it can’t communicate with the darn dimmer again.
Is this a firmware/software issue or are just the namron dimmers not compatible with the Homey or something? It’s far from (no pun intended) the adverticed 40m both devices claim to be able to do indoors :confused:

Those 40 meters is over spec’ed, 30 meters is the max for z-wave, but that is with no other 868mhz antennas nearby, which Homey does have, and perfect conditions (nothing that can interfere nearby, and nothing in between like walls, good if not perfect humidity, not too much other RF signals in the air, and a few things more)

While 5-6 meters is a little small, 8-10 is really the max (indoors) that Homey can handle in its current state (for most people), some people did do an mod to improve the range by changing the antenna out.

Inclusion is recommended to be done within 1 meter anyway, as Homey asks a lot of the device after initial pairing, way closer then 1 meter (like 10cm) is really recommended.

And a lot of things even just nearby can lower the range big time, copper wires for example, just nearby can be enough, or newer double (or triple paned) windows are awesome low frequency absorbers too.
But even a wall behind the device can be enough to lower the range.

Uhm so unless you live in a 40 square meter apt your pretty much f***d in other words? Unless you smack a wallplugg range extender in each and every vacant wall socket in the house :joy:

Well, every mains powered z-wave device is a repeater, doesn’t necessarily have to be a “repeater” specifically.

But yes, zwave is very much reliant on it being a mesh protocol that doesn’t use a lot of power, unlike WiFi.

Yeah, was hoping i didn’t have to swap out all my 433mhz dimmers and switches since Homey handle them fine, but seems like i have to anyways then :stuck_out_tongue_closed_eyes:

I have different problem with Namron dimmer switches. A few days ago I bought 8 of these switches. 2 of them I had to get replaced as they didn’t respond when I tried to pair them with Homey. After a couple of days, two more switches stopped responding. I have tried to uninstall them from Homey, and then I did a factory reset. Now they will not pair up with Homey at all. The purple “ready to pair” light is flashing, but there is no response in the Namron app in Homey. Any suggestions, please?

I have the same problem. Namron dimmers keep timing out. And even worse they stop responding to presses on the wall switch too.
Not fun when the bedroom lights cannot switch off.

Is it Namron that is incompatible with Homey? My electrician installed 17 of these in my house, against my instructions, I ordered Fibaro…

Elektroimportøren AS made a change in the software a month ago. After reinstalling the Namron dimmers in the Homey, they have all worked without a flaw.
