For the past few years I’ve been wrestling with Aeotec sensors (purchased because they seemed to be highly recommended everywhere). First it was spending weeks trying to get Z-Wave JS UI (nothing better than this??) to perform firmware upgrades, then replacing a Z-Stick 7 with an older version due to unfixable bugs in that, and now it’s on again / off again factory resetting and connecting the sensors back to the controller.
As time has passed my wife and I have essentially forgotten about automating anything based on temperature or presence. I replace the batteries in sensors from time to time (since they’re never not showing 100%) with no effect.
I ask because I’m planning on buying some Aqara devices that depend on WiFi. Preferably I’d like to use something other than WiFi since it’s usually the extremely congested 2.4 GHz band.
It’s just you. Have you considered zigbee?
I’ve got Philips hue lights that use Zigbee but I thought it also tried to hog 2.4 GHz spectrum; though I’m more open to it as of late considering my horrible luck with Z-Wave.
Zigbee and wifi do clash a bit more, but after I set my channels I’ve never had problems: https://www.metageek.com/training/resources/zigbee-wifi-coexistence/
My zwave has been bulletproof though. I suspect something is wrong with your setup, I assume you’ve tried things like healing the network?
Is your stick on a USB extension cable or hub extended away from your pc? That can help quite a bit.
