Have the samme issue that T1 Switch cannot pair with HP23 when Zigbee network is large. Seems to time out. Found a workaround for that issue here Aqara Single Switch Module T1 with neutral - #10 by Eide which works for me until it is fixed.
Would be nice to get a fix for getting the status of the switches in Homey app, as haven’t been able to find a workaround for that.
