I’ve just had a bunch of new devices turn up and I have added 5 of my new Xiaomi humidity sensors (WSDCGQ01LM) no worries, then I added a Xiaomi switch (ZNCZ02LM) and ever since that, I can’t get any devices to add? Sometimes it shows an error and tells me it timed out trying to get the device information, but 95% of the time nothing shows up in the logs at all.
I’ve done a couple of resets following the post here but it still doesn’t seem to be doing anything. Here are my logs from a restart I’ve just done. Does anyone have any suggestions on what I need to do to get the rest of my devices connected? I’m new to this so if more information is needed just let me know and I’ll do my best to supply.
