It seems that you got your wish. I guess it helps that part of Sweden is in the arctic circle.
Turns out the latest firmware for these devices doesn't use group messaging any more. It binds to one device only. I have both an E1743 and E1766, both can be updated to 2.3.079 (according to the release note this version introduces some security and it appears that you can not downgrade after this upgrade)
After updating the firmware with zigbee2mqtt and pairing to hubitat I was able to get a response with these two drivers
or
Neither driver is setup to deal with the way the buttons work on either device but the bind request was successful. The first driver half works (only hold on the 0 button doesn't work on the E1743). The E1766 works differently as it is for the blinds so the drivers for that will need more work. Also, I had a hard time getting the configure command to bind the clusters. After I set the driver I wanted to use I had to repair the device to hubitat, then when the existing device was found click to go to the device page and hit configure before the ref pairing light on the button turned off. Probably, would work better if a driver with a matching footprint was present.
