Unable to connect to ELK-LAMPL

[Merikei]

Awesome integration! But doesn't seem to work with my specific LEDs that are normally controlled with Lotus Lamp X (Google Play)

Name starts with: ELK-LAMPL

[dave-code-ruiz]

only one question,

Work for you commands to power off and power on your specific LED ?

sudo gatttool -i hci0 -b be:16:fa:00:04:2a --char-write-req -a 0x0009 -n 7e0004000000ff00ef # POWEROFF
sudo gatttool -i hci0 -b be:16:fa:00:04:2a --char-write-req -a 0x0009 -n 7e00040100000000ef # POWERON

[Merikei]

Those are the commands I ran, so not sure if I'm missing something, but I did check they worked when I ran them.

[dave-code-ruiz]

ok, test version 1.2.1

I think it is posible to work to you

post results and logs please

[Merikei]

It works!* 🎉 Thanks!

• 🎉 Adjusting the brightness, turning on and off, and setting solid RGB colours works 🎉

• *I don't care about this, but the effect names don't match the effects that occur, though all do something.
  My LEDs are a 20×20 grid which may explain the difference
  Happy to debug including log Bluetooth packets from LotusLamp X if others want, though.

• *The whole device in Home Assistant shows up as being called "Effect Speed LED curtain" in Home Assistant (when I tried to name it "LED curtain")

• *I'd expect number.effect_speed_led_curtain to be called number.led_curtain_effect_speed

• *Setting the effect speed doesn't do anything. I tried other speeds but have just included setting it to 100 (max) and 0 (min) in the log below.
  I don't care about this, but again, happy to debug if others want.

• *Included logged deprecation warning

• One last thing:
  I use the "Gallery" mode in LotusLamp X which lets me pick from a few pixel art animations. This now lets me change the brightness and turn it on and off from Home Assistant, which is what I was mainly after, though I am interested in being able to send custom animations via Home Assistant, since while LotusLamp X has a "DIY" mode, there's no import or export option and the editor doesn't allow for picking exact colours.
  Any ideas?

Wow! Good news!

I'm very happy

You could buy me a coffee if you consider it as a thanks

I'm glad to hear that, I'll ask you for help to make changes when I have time
