This is the response I got back from support… Sadly pretty useless…
"This is Diedra from Samsung Smartthings, thank you for all of your time and patience as we work to resolve the issue with your Ikea button draining batteries fast. I did send this up to our developers for a response. They ask for you to reboot your hub by unplugging it and removing the batteries for 10 to 15 minutes to re-sync it to our cloud.
If this does not work, the last step from our end would be to delete the hub and fully factory reset it then add the hub and devices back. This is an older V2 hub which has been running over 4 years, so the reset can help. Before doing this they do recommend that the buttons be replaced incase the issue is on the buttons end.
If you have any other concerns please dont hesitate to call us at 1-800-Samsung Mon through Sat 9AM till 9PM EST."
I will go back to the Ikea hub i see no other option
