FA21RF Fire Alarm

---

Hello,

I’m new to pimatic. I was able to install pimatic on my Raspberry pi and connect the receiver/transmitter. I have 5 FA21RF fire alarms and I saw that it should be supported as “alarm2”. If I enable debug and push the fire alarm button I receive this:

21:22:23.218 [pimatic] info: Listening for HTTP-request on port 80...
21:25:39.480 [pimatic-homeduino] debug: data: "RF receive 8100 804 2736 1388 12188 0 0 0 0112131312131312121212121212121212121313121313121314"
21:25:39.539 [pimatic-homeduino] debug: received: [ 804, 1388, 2736, 8100, 12188 ] 3002010102010102020202020202020202020101020101020104
21:25:39.572 [pimatic-homeduino] debug: alarm1:  { id: 9699218, state: true }
21:30:43.747 [pimatic-homeduino] debug: data: "PING"

So it finds my device and I can see that its has ID 9699218. But how do I insert this in mij config as device? I already tried a couple of things, but it just does not work. It’s a beginner question, but I just does not work.

Thanks for the help.

@Nils-Vanhauwaert try this one:

{
  "id": "smoke1",
  "name": "Smoke alarm",
  "class": "HomeduinoRFPir",
  "protocols": [{
    "name": "alarm1",
    "options": {
      "id": 9699218
    }
  }],
  "resetTime": 10000
}

That was a quick answer! I will give it a try this evening. To understand the above thing better. What are “fixed” fields and what not?

I mean:
ID: this can be something I can choose but must be unique (?)
Name: This can be something I can choose but must be unique (?)
class: Don’t know where this came from. I think that these are fixed classes from the Homeduino plugin, but I can’t find the info
Protocol: I found that he FA21RF fire alarm uses “alarm2” as protocol. Or do I have to use “alarm1” like you wrote?
ID: This is the ID of the device

What does resetTime does?

Thanks !

ID of the device: a unique name for the device (may not include spaces).
Name of device: the name that is shown in the front-end.
class: it specify’s the device, so pimatic knows which device it it.

then this device has protocols (you can add more than 1):

Name of protocol: the unique name of the device protocol see here (named protocols): https://github.com/pimatic/rfcontroljs/blob/master/protocols.md

and each protocol has some options, like an ID and/or Unit code (depends on the device)

The resetTime is needed for devices that only send a true signal, so the status of the PIR resets after 10 seconds.

Where do you get the name: “HomeduinoRFPir” for the “class” object? Is this something you have chosen or can I find that thing back in a pre-defined list?

to come back on the resetTime object. Because the fire alarm does nothing the most of the time, it only sends a signal when there is smoke detected (True signal). So after 10 seconds the fire alarm will stop beeping, and wil restart immediately because there is still smoke, and will stop beeping again after 10 seconds…

Or am I wrong?

See here for the names of classes (devices):

https://github.com/pimatic/pimatic-homeduino/blob/master/device-config-schema.coffee

like : HomeduinoDHTSensor, HomeduinoDSTSensor

In every plugin you can find this device-config.schema. Here you can find the supported devices and the options of that device.

The smoke alarm won’t stop beeping, pimatic can only receive a message from the smoke sensor. the smoke sensor can’t receive messages. So that resettimer is only for pimatic self.

But i don’t know what happens when the smoke detector doesn’t see smoke anymore. Does it send a ‘false’ message then? If it does, you can replace the "resetTime": 10000 by "autoReset: false"

Hello again,

If I took protocol Alarm 1 and class HomeduinoRFPIR" I received a couple of errors.
In another threat ( http://forum.pimatic.org/topic/548/solved-fa21rf-smoke-detector-alarm2/8 ) they use other values. I changed HomeduinoRFPir to HomeduinoRFSwitch and played wilt alarm1 and alarm2

If I start Pimatic it detects and connects with the device, so it’s looking good. Then I go to the Devices page and add a on/off button on the front screen. If I push the On/Off button nothing happens.

This is the log:

I’m a complete noob like you see…

TIA

I see, i thought it was a pir device but its an switch. Can you set the smoke alarm in learn mode? if so, set it in learn mode and switch it on in pimatic.

@Argon
Most of the settings for Homeduino are declared here.
https://github.com/pimatic/pimatic-homeduino

The linked thread has solved the problem so you should use the same config but with your protocol id’s.

@AvdH , I can’t reply anything in your previous topic about the FA21RF. Can you please show my your code to see how you configured the FA21RF in Pimatic? The goal is that I can power on/off the fire alarm from within Pimatic, and when it’s on, I want to receive a mail.

But my first step to power on / off the fire alarm from Pimatic just don’t work. Can you please help me a bit?

Thanks!

My code looks like this:

I have made a variable $alarm-on (value false)

then under devices:

{
  "id": "alarm-upstairs",
  "name": "Alarm upstairs",
  "class": "HomeduinoRFSwitch",
  "protocols": [
    {
      "name": "alarm1",
      "options": {
        "id": 13841XXX
      },
      "send": true,
      "receive": true
    },
    {
      "name": "alarm2",
      "options": {
        "id": 13841XXX
      },
      "send": false,
      "receive": true
    }
  ]
},

and

{
  "class": "DummySwitch",
  "id": "alarm-botton",
  "name": "Alarm button"
},

under rules:

{
  "id": "switch-alarm-on",
  "name": "Switch alarm on",
  "rule": "if alarm-button is turned on then $alarm-on = \"true\"",
  "active": true,
  "logging": true
},
{
  "id": "switch- alarm-off",
  "name": "Switch alarm off",
  "rule": "if alarm-button is turned off then $alarm-on = \"false\"",
  "active": true,
  "logging": true
},
{
  "id": "start-alarm",
  "name": "Start alarm",
  "rule": "if \"$alarm-on\" = \"true\" then switch alarm-upstairs on and switch Alarm button on",
  "active": true,
  "logging": true
},
{
  "id": "alarm-is-going",
  "name": "Alarm is going",
  "rule": "if every 30 seconds and \"$alarm-on\" = \"true\" then switch alarm-upstairs on",
  "active": true,
  "logging": true
}

For some reason the alarm only goes for 5 or 6 seconds.
The last rule makes it go ever 30 seconds, maybee a shorter time also works.

If someone has a solution for the short alarm-time i would like to know.

Hello @hansjeu,
could you solve the 5 second problem?

Hello SaxnPaule,

The problem has not been solved yet. I am no investigating an option to use a read alarm-buzzer on a wifi-power-switch from sonoff.

I solved the problem with a workaround: https://forum.pimatic.org/topic/2991/big-problem-with-alarm1-alarm2
