I have gotten the updated Zooz ZEN26 and ZEN27 firmware which supports Central Scenes and now need to update about 10 devices.
Zooz provides a utility for updating and I also have the HomeSeer Z-flash utility.
I’d like to use the HomeSeer utility as it can connect to the SmartThings hub as a secondary controller. Also the HomeSeer utility can do batch updates.
My question is: should it work to update firmware from the secondary controller (i.e., without removing the device from the SmartThings Z-wave mesh)?
