Automatic battery type fill-in
Actually I’ve had this implemented for months but never released it to the public because SmartThings had a bug when adding that information. They fixed it and has been working fine since. It adds this little arrow to the battery percentage and you can check the battery type and quantity.
Setting for old TRADFRI with new 24.x firmwares
In the rare case you have old TRADFRI remotes with new firmwares (24.x), highly improbable since you had to update them in another platform, I’ve added a new setting to fix the battery reporting. Used to be automatic but SmartThings broke firmware version reporting to drivers as stated in previous comment so now you have to tell the driver manually or it will display double the battery
