I have 4 IKEA GU10 light bulbs in close proximity of one another in the centre of my bedroom. Individually triggered, all of these work perfectly. But when triggered at the same time, like when triggering them as a group or in automations, there often is a substantial delay. I’ve come to notice that this is because when turning on/off 3 or more of these bulbs at the same time, the state won’t change in the app on one or two of the bulbs. Sometimes it just takes a couple of seconds, but frequently it never does update the state. Since, I believe, that automations wait for that state update, there is often a delay of the actions that are set to be triggered later the in automations. And to be clearer, the state of the actual device, as in turning the device or off actually works, its just the virtual state in the app that isn’t updated, which causes problems/delays for my automations.
I am not using the Ikea Gateway, deConz, Phoscon, Zigbee2Mqtt, etc, etc… I am have connected the bulbs directly with a Conbee 2 USB-stick, through ZHA. initially, I thought the problem was interference, but after trying different Zigbee channels and testing other devices, I can say that it’s not, unless it has to do with the close proximity of the devices. They are after all mounted around 20 cm from each other. All devices do work great with this one very specific exception.
I can’t think of a solution to this issue and I have not seen a similar problem yet, or maybe it is too basic of a mistake to make.
Anybody got any ideas as to how to fix this, or got any suggestions that I might try?
Thanks in advance!
