I've been using Raspberry Pi 4 with Node Red managing IKEA tradri lights and switches for the past 6 months. As well as lighting I get data passed to Grafana for my solar panels, central heating and weather from Darksky.
The lights and switches are controlled with Bigtimer coming on twice a day.
Recently the connection between Node Red and the IKEA hub seem to be be broken and I have to reboot the IKEA hub and re aquire the pre-shared key.
Is this a known problem and is there a fix?
