That’s LightwaveRF. Lightwave is a different product.
But LightwaveRF Integration is excellent. That’s a UK company, very popular because they make light switches that do not require a neutral wire. (They are also HomeKit compatible, although I don’t know if you can use both integrations at the same time.)
Anyway, I assume this will require the lightwave RF gateway and is cloud to cloud, but still very cool.
ah, you’re right. Ecosmart is a brand of light bulbs sold at Home Depot. can’t find any for sale, but recent PR against the SmartThings github shows them as a zigbee bulb.
