Acknowlege on a received push-button message

[Speed-xD]

Hey, first let me thank you for the great documentation!
I wrote my own GUI to communicate with the MAX Devices over a maxCUL Stick.
All my thermostates work fine. Now I have add an push-button.
My question is about an message from a push-button.
So the pairing works well.
When I push the button itself, I receive the following message:
Z0C0D025007FC4B112112001000
That looks right to the excpected answere.
But a feew seconds later, I receive this:
Z0C0D025007FC4B112112005000
The last message comes a few times.
Also the LED on the button blinks 3 times so I think the button waits for an answere from me.
I can't find an acknowlege message which I have to send in the documentation.
Can you help me with that?

Hi Speed-xD,
you‘re very welcome!

The first idea that comes to me is that the Auto Acknowledge feature is maybe not enabled.
Therefore you have to send the following message to CUL (after enabling Moritz mode):

Za
||
++--------------------------- Enable Auto Acknowledge

See CUL-stick.md → Enable Auto Acknowledge:
If Auto Acknowledge is not enabled, the Push-Button and the Shutter-Contact repeat their state-messages five times.
So far I have not been able to decode the first byte of the payload. Maybe it's some kind of counter.

Let me know if this has helped you.

p.s.: I would be very interested in your GUI, will you release it on GitHub?

Thank you very much for your quick reply.
That helps me!
Unfortunately it's not describe in the culfw reference:
http://culfw.de/commandref.html#cmd_Z
So i had a look to the source code and find out that the command "Za" alone doesn't reach.
Correct is to send "Za123456" where 123456 means the ID from the NanoCUL in Hex.
Like for me "Za112112".

Independently I found an issue in the protocoll documentation.
In the part for setting the time, minute and second are swapped.

#### Decoding payload (Thermostat set time information)

I will upload the source code for my windows gui next time and let you know :)

I'm glad that I could help

You are right, after the Za, the CUL source address is missing and
in the decoding of the time information payload, the minutes and seconds are swapped

Thanks for the correction, i will improve that.

If you have any further improvements or additional information, pull requests are very welcome.
