Add FA20RF support

[Xento]

Could you add support for FA20RF smoke detecors? It is already supported by fhemduino, there you could get the protocol from. I looked at your code but I don't really understand where to implement the different timings. Is there any documentation?

[Icesory]

Ca you post the protocol Dokumentation? Think next weekend I got time to make some work

[Xento]

Here is the file used by fhemduino. https://github.com/mdorenkamp/fhemduino/blob/master/lib/FA20RF.cpp

I think I understood how it works. I will try it by myself. But we need a special device definiton in pilight because it acts like a pir when receiving. It sends the alarm every 2-3 seconds when on and this stops when the alarm turns off. When you want to send alarm you have to send the alarmsignal every 2-3 seconds so that the smokedector stays on.

what about protocol name "alarm1" ? i'm having this device too, so i could check if your protocol works for me also.

ups pilight?

In pimatic we can either abuse a pir-sensor (there is an autoreset option) or we can create a new alarm device.

[Xento]

The best would be a new alarm device where you could set an interval for repeating the signal.

When I press the test button on one smokedetector I receive ths from homeduino: received: [ 744, 1464, 2807, 8092, 17292 ] 3002020101010102020201010101020101010102020202010204

Look at my fork for the changes I did. https://github.com/Xento/rfcontroljs/blob/master/lib/controller.js https://github.com/Xento/rfcontroljs/blob/master/lib/protocols/alarm1.js

In my eyes it should work now, but it doesn't.

[Icesory]

Why do you want to encode a message? Think this isn't necessary.

[Icesory]

And you killed a bit. ....010-204 You have 204 declared as a nothing but I think it is one bit more to decode. So only 04 is the header

[Xento]

The decoding is nessesary to detect which smokedetector sends the alarm. Yeah you were right, I missed a bit. Now receiving works but sending not. This is received when i press the testbutton: 3002020101010102020201010101020101010102020202010204 And this is send when sending via pimatic: 0020201010101020202010101010201010101020202020102003 The 3 at the beginning is missing and 03 at the end should only be 4.

[Icesory]

The decoding is necessary. But why do you want to send from pimatic? How should this work?

But it looks right.

[Xento]

You could use the smokedetecors as alarmsirens. For example if you are not at home and one windowsensor detects that a window was opened.

[Icesory]

That is a nice feature. I have look in to the fhemduino protocol and your implementation is right. Strange that you get a wrong encoded message.

Can you create the coffeescript source file? The normal language for pimatic is coffeescript.

[Xento]

Finaly I got it working: https://github.com/pimatic/rfcontroljs/pull/40 I can understand coffescript a bit, normaly I try to copy&paste things and use try&error to get the coffescript working. Could you create the coffescript?

[Xento]

I made a rule, to continuosly send an alarm: if SomeSwitch is turned on or [SomeSwitch is on and smokedetecor is turned off] then switch smokedetector on and after 4 seconds switch smokedetector off

[Xento]

@leader21 could you test the protocol, too?

[Icesory]

I will implent this to pimatic but i think the coffeescript ist not right. Why do you need a loop in the encoding part?

[Xento]

The rf signal must be repeated a few times until the smokedetecros responses. I thought a loop would be much nicer and more dynamic than repeating the pulse string. In fhemduino the repetion is configureable.

[Icesory]

Homeduino sends the RF message normally 7 times. I have merged your work into my reporsitory. can you take a look on this? I made some changes to fit it into the pimatic coding style

[Xento]

Without the loop I have to switch the device on and off for about 3 or 4 times until it goes on.

[Xento]

And your version sends the signal when turning off the switch.

[Xento]

Double post? I used your changes.

[Icesory]

Oh yes double post. Sorry I have found the failure while sending

[Xento]

Ok, this looks better, but the problem with the sending/receiving is still there. I have to turn the switch on and of multiple times until it works.

[Icesory]

And now?

[Xento]

Now it works

[Icesory]

Nice. And the other protocols?

[Xento]

Home Easy Advanced works, too. I can't test the belldoor, because it was a user request and I don't have one
