Hi, thxs for answer.
On Settings page I see
Vendor: dresden elektronik
Product: ConBee II
Version: 2.11.05 / 9.5.2021
Firmware: 266B700
I made downgrade to this FW-Version manually, because some weeks ago, everything was working in phoscon app. I don’t know exactly when the error was the first time on which fw-version.
I also have tested the latest beta versions.
Additional the conbee II stick is connected to a iobroker linux installation. With iobroker the control of the lights is working well!
