I’m working on controlling my bed (Bluetooth Octocontrol, which is supplied with remotes and an App).
My primary goal was to control the under-bed light as also part of my setup.
I got that part working with an ESP32, ESPHome resulting in an on/off switch in Home Assistant (my first time analyzing bluetooth traffic 
).
I used wireshark to analyze the bluetooth commands to control the bed (as send from the app on my Android phone). I got all commands logged and all are working.
My challenge… I also want to control bed movement and when I send the bed-head-up command it moves the bed-head up for a fraction of a second and then stops. In the wireshark logging I see a continuous (every +/-300ms) repeat of this command which results in a continuous move.
I wonder what the best approach to create similar behaviour in ESPHome would be and home somebody can help me. I looked into a first button to start movement (start while loop) and a second button to stop movement (stop the running while loop). Or possibly use the cover component (time based?).
What would be the best approach? And how could I set this up?
To also share my work so-far:
All controls (head / feet / head/feet combined / lamp) all use:
[Service UUID: 0xffe0]
[UUID: 0xffe1]
Specific commands:
Head up : 40 02 70 00 01 0b 02 40
Head down : 40 02 71 00 01 0a 02 40
Both up : 40 02 70 00 01 07 06 40
Both down : 40 02 71 00 01 06 06 40
Foot up : 40 02 70 00 01 09 04 40
Foot down : 40 02 71 00 01 08 04 40
When logging I see repeating the commands above, for as long as the button
is pressed. After that I see the following command: 40 02 73 00 00 0b 40
(which does stop movement I guess, even in shorter than 300ms period?)
Lamp control
ON 40 20 72 00 08 de 00 01 02 01 01 01 01 01 40
OFF: 40 20 72 00 08 df 00 01 02 01 01 01 01 00 40
And in addition my existing ESPHome control for the lamp

im trying to control my Linak motorized bed . I have the values to control it but the stupid thing is that I need to press release the button in ha multiple times to get the bed up or down - one press just execute a short move 
is it the same with yours ?
