Hi,
First things first, here is the equipment i’m using:
Homey Pro 2023 firmware 10.1.0 (z-wave region EU)
Homey Bridge firmware 81
Home Assistant 2023.11.3 with Z-WAVE JS UI v.3.0.1 and Aeotec Gen7 z-stick (and also spare gen5)
Different z-wave devices (about 50): Fibaro smoke sensors, NeoCoolcam smart plugs, NeoCoolcam motion detectors, Qubino DIN-rail dimmers, Aquara sensors, ROBB smart
A few zigbee devices (about 6) also from Ikea, ROBB
Also about 20 shelly WiFi devices.
Migrated everything from HASS (running for about 4 years without problems) to Homey 4 weeks ago and everything works (almost) flawless.
No coming to the issue that started about 2 to 3 days ago. My Z-wave network became unstable. Unstable in the way that some of my devices no longer work, especially the devices that where somewhat further away from the controller. If i look in de homey developer tools, i see that devices became unreachable, but not only the devices that are far away from the controller, but also about 50 cm. from the controller and on main power.
First thing i tried was to restart homey, but this was not resolving the issue. Also most of the devices could still be operated even if they are in the state unreachable. Homey would throw the famous TRANSMIT_COMPLETE_NO_ACK but the device would turn on or off after a while. Some of the devices where completely lost and failed, so i removed them. Also the bridge just disappeared from the z-wave network, but is still visible in Homey itself and state is ok.
Now comes the good part. I wanted to re-include the devices that where failed, but inclusion does not work at all. Tried to exclude first, reset z-wave + device, tried different sensors from different brands, non of them could been included, excluded, re-included. Very strange. Also the communication in the network, as far as is can see with the developer tools, is verry, verry, verry low, only a handful of TX and RX packets and logging does not show much. I’m completely clueless at this point…
But wait, it even gets better… I decided to reinstall HASS on a new NUC, plugged in my Aeotec gen7 z-stick and guess what…i can not include or exclude any device! So back to the installation with the Aeotec gen5 stick that always worked and yes could you guess my problem? Yep, did not work at all…
So for the moment i’m also in contact with Silicon labs, but for now i’m waiting for a solution if there is any…
I know that z-wave does not interfere with WiFi or bluetooth (everything is Ubiquiti material and runs for many years, only thing that changed recently is the router from USG to UDM), but what can also interfere with z-wave? It’s like something/someone is jamming all z-wave traffic in my house.
I’m really clueless or missing something here.
Anybody got some ideas?
Kind regards,
Tim
