The GE switches don’t capture the double tap at the switch. The smart apps are trying to time it in the cloud, which introduces a lot of uncertainty.
The homeseer (US) and the Devolo(UK) work differently. They are using the Z wave “central scene” Commandset. This captures the double tap or triple tap at the switch and converts it to a button code, then sends that code to the hub. So no cloud latency issues.
If you need double tap I would go with one of the switches that supports the central scene command set right now.
