Support for Livolo is almost impossible in HE. According to information that I found two other systems/hubs introduced "hackish" support for Livolo. I own one piece of two gang Livolo switch (bought for tests), and I spent three moths attempting to force it to work with HE. Livolo could be very good, but unfortunately Livolo uses strongly modified Zigbee protocol, to be specific:
Livolo need permanent "device discovery mode" on hub,
Livolo make a lot of zigbee traffic, overloading standard zibgee network,
Livolo using custom (non standard) commands.
I'm strongly suggesting usage of other switches. Look for hardware that uses standard clusters or wait for support for "Tuya" switches that uses cluster EF00.
