Any ST & HA-Bridge integrations?

Smartthings introduced a “device health” feature for the V2 hub which pings various devices and marks them as “off-line“ if they don’t respond. This frequently causes problems of the type you’re seeing for virtual devices, which don’t respond when pinged.

For the V2 hub there is an option to turn it off, but I don’t know if the same option is available for the V3 or the Wi-Fi connect home versions.

I know there are a number of community members using the “Homebridge” emulator to get HomeKit integration through a hue bridge emulator; @pizzinini might know if they’ve seen similar device health issues with that emulator.
