Mine have been pretty rock solid. I gave up on using HomeKit to control thread devices though. I’m pairing them to directly to Home Assistant directly with a ZBT-2, and then I share my devices to HomeKit as a Bridge.

Alkaline batteries don’t have a consistent voltage (they start higher and drop faster).

Can't help with the Bilresa, but I can with the Myggbett: I've got Myggbett door/window sensors and Alpstuga air quality sensors running via Matter over Thread, with my Apple TV as Thread border router. No dongle involved for Thread at all, and they've been rock solid in HA. The good news for you: you don't have to tear down Z2M. One radio = one protocol (running Zigbee and Thread on the same dongle via multiprotocol is deprecated and flaky anyway). So keep the MG24 on Zigbee for the Bilresa and get Thread from a separate device: * Apple TV 4K or HomePod mini (careful: the 64GB Wi-Fi-only …

They're made for the ikea Ladda batteries, which run at lower voltage than standard AAA.
