Neo coolcam smart plug with power monitor

Hi there,

I bought 4 neo coolcam power plugs woth energy monitoring:

Does somebody know how to configure them in esphome?

I’m not sure you need esphome to integrate those into home assistant. Did you have an idea for connecting these to an ESP somehow?

I can using tasmota, but I really prefer esphome…

I have one on ESPhome, I have to look tonight after work for the code.
Energy monitoring is working only the LED is not working.

Ok,looking forward to it. I’m on tasmota, currently and the led is flashing in off and on mode…

did you flash them with tasmota? Which tools do you use, the old tuya convert, the new tuya convert, or?

This is the Esphome yaml code I used to flash the neo coolcam smart plug.
Everything is working except the LED, if I have some spare time I will figure it out.

I used the Tuya-Convert 2.0 on a fresh raspberry. Works very well for me. Flashed 4 devices without any problem.

Thanks. Led and button aren’t working for me, but remote it seems to function very well.

For the first flash i had to remove the web_server part. It didn’t compile. Not tested, but it should work if you add it in a second flash.

For remote you intend the switch (on/off)?

Yes, and the sensors values are coming through. But it seems the button is not working neither does the button-LED.

Oh, the LED I do not care, but button could be important to have. Have you tried all the GPIO?

No I didn’t had the time yet. But i hope to find some documentation about this product :slight_smile:

can you open it (without breaking it)?

No screws present, but it should be possible. It’s something i try to prevent, thats why i’m so happy with the Tuya-Convert 2.0…

Info about the plug from the Tuya Convert Wiki site:

GPIO0: Button1 (17), GPIO04: HWL8012 CF (133), GPIO05: HWLBL CF1 (132), GPIO12: HWLBL SELi(132), GPIO13: Led1i (56), GPIO14: Relay1 (21)

yes of course, just to see the pins to the ESP

but seems incorrect if sholoffy followed the code above

well, I stick withe Osram + , they cost 34 Euro 4 pieces (sometimes on offer in amazon) and with Zigbee less problems, at least for me.
Unfortunately no power metering and 10A

I think it is correct but there is no action attached to the button in the above code.

If you add something like:

      - switch.toggle: relay

to the binary_sensor it should work.
