Question about Sonoff SNZB-01P

Does the button work with the Govee lights that are also controlled with Google Assistant? The Govee Switch doesn't seem to be available anywhere...

No, I tried it even with new firmware and it didn't work. This is due to the Friends of Hue story Signify only allows accessories from certified partners. Unlike the light bulbs. I have integrated the button into the Home Assistant using the Sonogr Zigbee dongle.

I can't answer that, but I can tell you that it works with Ikea's Dirigera gateway.

From my point of view, only Hue products and "Friends of Hue" are compatible with the bridge. I would have said that it can't be integrated, but I'm happy to be proven wrong. Although it is also Zigbee, this does not mean that everything is compatible with each other or that the bridges of the individual manufacturers allow all products.

If you have ZigBee, then yes, because Hue can also do ZigBee.
