I picked up some of the Linkind Smart WiFi RGBW Light Bulbs. I was hoping to get them to work with HA but so far I have had no luck. I have them on my WiFi network and they work fine with the Linkind app on my phone but I don’t see an integration with HA. I saw a video from Paul about " RIDICULOUSLY CHEAP Philips Hue Alternatives". He didn’t mention how he was controlling them but he mentioned hubitat and some other methods. I assumed (I know bad idea) that they would work with HA since it is the best thing since sliced bread. Does anyone have a way to get these to work with HA yet?
I saw that video few days ago, but I think Paul was using Zigbee linkind bulb not the WiFi linkind ones!!
He even recommended to connect via Philips hub which is a zigbee.
Didn’t find the zigbee color version on amazon USA though— only white.
Yeah, and Customer Service is HORRIBLE… one bulb (that I didn’t rip apart) was bricked in the box, and they send multiple emails with each individual step… then tell you to send them pictures and screen shots of everything
I hate that you had a bad customer service experience with them. I just had a couple of emails back and forth and then I got an RMA number to send them back.
Any update on this? I just got 4 of the linkind bulbs and I have liked them so far… but they do not work with HA. Is there a way to “ask” for an integration or something like that?
Hey! I’ve registered on this forum just to let you know that I was able to make it work!
And it’s pretty easy actually.
All you need to do is to RESET the bulb, as it’s by default connected to the LINKIND controller. In order to reset any smart bulb, you need to quickly turn it on and off 20 times.
After that, I was able to connect it to my Sonoff zigbee dongle.
I have the Smart Light Bulb RGBTW, and I’m also looking for a way to connect these directly to Home Assistant.
Some things I notice:
if I block them in my router’s firewall, the AiDot app will eventually connect to them using bluetooth. If someone adds support for these as a bluetooth device, that might allow local control without the AiDot app
These are definitely ESP32 devices, so these can probably be flashed with Tasmota or ESPHome. ESPHome would be cool as these have both Wifi and Bluetooth; maybe they could act as a bluetooth proxy.
I watched this video where he disassembles a similar bulb for flashing, all I’ve accomplished is slightly damaging the edge of the LED board. I think there’s adhesive under it and there’s really enough enough room for me to get any tools under the edge without crunching the edge of the board. So probably leaving the factory firmware installed and using BLE to control them is probably the best bet, but of course someone will need to write a driver.
FCC ID is 2AW95LS0102111261. Maybe I can find more, but I at least on FCC.report, they don’t show it any more disassembled then I already have it (just the diffuser removed).
It’s visible in the previous photo I uploaded, but there seems to be some connection from the board to the metal housing near W6, W10, and W8. I thought maybe it was a tab folded over and soldered, but I didn’t have much luck attempting to unsolder (I’m not sure if that is solder or just metal). I cut through the one by W10 (the white LED next to B5) and didn’t have any better luck attempting to pry up in that gap near W11.
I can’t get a good picture of inside the device from the socket end, but it appears that there’s an aluminum disk under the board, probably some sort of heat spreader. This is a 1600lm model, so it’s a bit higher wattage than some of the others. I think I can see light around the edges (if I shine a bright light one the front side and look up through the socket end, but I’ve tried a LOT of pressure and it doesn’t seem to budge. I have scratched up the heat spreader a bit.
From the top, that ring around the edge seems to be aluminum. It doesn’t melt from a soldering iron and solder doesn’t stick to it very well. When I apply a solder pen to that ring, the whole side of the bulb warms up.
If it is 2 pieces (a disk and an open cone) I think I might need to find something that more closely fits in these slots at the base of the bulb.
…
So the interior sides are metal. I think they have a metal cone heatsink glued to the plastic cone of the product body. And a metal disk glued to the bottom of the LED board (That’s what I’m pushing against). But I think when they assembled it, they crushed the top edge of that “heat sink cone” to create that bulge. It’s not clear if the circuit board itself is pushing against it, but I think the heat spreader under the circuit board is.
It’s not, just clamped with the screw at the bottom
Try to record a video of this, might help if I can spot any way to remove the led plate
The only led bulb I couldn’t disassemble was a fitop, there’s this metal case under the led plate that just won’t budge. Great build but teardown is pita
