Using the blinds with a second gen hub now for about four years. No problems at all. Dreading the day they fail as they’re non-negotiable during the summer.
FWIW I bought some Zigbee blinds from Amazon and they’ve been great. My windows weren’t the right size for the IKEA ones and the sellers on Amazon will custom make them for you to within 1/8 inch or something like that.
I went through the whole blind research rabbit hole and ended up with Smartwings via Amazon. I had looked into a lot of other providers and nothing had a similar combination of reliability, cost, and customer service.
