Hi, I’ve got an problem with my Sunricher dimmers (SR-ZV9040A\_Micro\_Smart\_Dimmer). Intermittently they just stop working. The problem that occurs is that I cannot controll them via Homey anymore and also the physical switch on the wall stops working (momentary switch) I got this problem with several of my dimmers. The faulty device reports unknown and unreachable on the developer site. Troubleshooting done: - Tried to heal all my z-wave devices, just not the one that got the problem. - Rebooted Homey - Can’t remove the device from settings. - Removed it from the developer site, but can’t add it again - all the other Z-wave devices works fine at the time. - Tries to press the switch on the wall 3 times fast. Also tried to hold it down for more than 10 seconds to see if it resets. The only thing that fixes it (what I know) is if I open up the wall socket and just press once on reset on the dimmer, then it starts working again. Both in Homey and the switch. So I do not need to remove it or anything before doing that. Tried to find info regarding this, but couldn’t. Any suggestions? Thanks! Regards, Johan ---

> [@\[HOW TO\] Adding a Z-wave device to Homey](https://community.homey.app/t/how-to-adding-a-z-wave-device-to-homey/19148): > > Adding a Z-wave device to Homey This post is to try to help adding a Z-wave device to Homey. There is a lot of posts on the forums where Z-wave devices could not be added and where is stated that it must be a broken Z-wave chip then. Am not saying that’s impossible but most of the times it can be solved with below steps. If adding a Z-wave device is failing (for whatever reasons) then please try this below steps. Please try to follow the steps with love. Like where the PTP states to wait at … be sure to follow all the steps in this link, if it doesn’t help, probably your device is broken. ---

I don’t got any problems to add the devices, it’s that they stop working randomly with the described problems. Also think it’s a bit unlikely that 3 dimmers should be broken 😕 ---

If they aren’t included the right way (fi. to far away from Homey), you can get all kind of strange behavior, jus mentioning it, I have no other idea, succes. ---

Hi Johan. Did you manage to solve the problem? I’m experiencing the very same. I recently installed 8 Namron dimmers which are the same as Sunricher, just branded different here in Norway. In the past two days, 3 of the dimmers have stopped working at randomly, leaving lights on or off depending on state before they failed. Turning off the power to these (through the circuit breakers), will bring them back to life again (quicker than disassembling the switch to press the reset button). As it is, the behavior of these dimmers makes them useless, so I hope there is a solution to this. Best regards Eirik ---

Hi, I have the exact same issue. Did you guys figure it out? Best regards Philipp ---

Bumping this thread. Just recently bought and installed two Sunricher Z-Wave Rotary dimmers. I have experienced exactly what you described above. It can randomly “hang” and I need to flip the switch on the fuse circuit breaker to fix it. As someone said above, it’s rather useless if continuing like this. Interesting though that five years later than the first post in this thread… Not sure if you are still around but would be interesting to know if you solved it somehow? Or perhaps if anyone else had this issue lately? ---
