Recently picked up a bunch of Ecosmart zigbee tunable white bulbs with the remotes at Home Depot. Several of my zigbee end devices (both ZHA and ZLL) picked these up as repeaters and they’ve been working great this way for over a week. Not surprising considering these are zigbee 3.0 certified I suppose. The <$5 price on these is a steal, especially considering they come with a remote. They also get very very dim at the lower settings unlike a lot of my other smart bulbs.
I haven’t been able to force any of my Xiaomi/Aqara zigbee sensors to use these as repeaters yet, so I’m not yet sure if they’ll play nice with them like the Ikea Tradfri devices or not.
