Doorbell script question

[gschmidt]

Hi,

I have bought a cheap 433mhz doorbell (from the Action).
With "learned" it created a "Doorbell" switch in Domoticz.

My goal is to send a notification e-mail to my phones when the fysical doorbell button is pushed.
The problem is that when the knob is pushed, a series of packages is send (in the Log I see in a short time 3 to 5 records)

2019-02-09 11:10:28.192 (RFXtrx433XL) Lighting 4 (Deurbel)
2019-02-09 11:10:28.240 (RFXtrx433XL) Lighting 4 (Deurbel)
2019-02-09 11:10:28.269 (RFXtrx433XL) Lighting 4 (Deurbel)

Which means 3 to 5 e-mail notifications...which is not what i want.

So as a workaround, I created a dummy switch, and with a blockly script I set the dummy switch to ON, when the doorbell is pushed.
With another blockly script I create the e-mail notification and also set the dummy switch OFF after 180s (see attachments)

I thought that the blockly script would understand that if the dummy switch is set to ON, it cannot be set to ON again (since the doorbell is sending 3 to 5 packages.) However, I still receive 3-5 e-mail notifications.

Somebody got an idea how approach this?

What happens if you add a user variable (string in this case)?
So you'll get something like:

Code: Select all

If [ [ [Bel Schakelaar] = [On] ] and [ [var Deurbel] = ["niet aangebeld"] ] ]
Do [Set [var Deurbel] = ["er is aangebeld"] ]
   [Send email]
   [Set [var Deurbel] = ["niet aangebeld"] after [10] seconds]

This way it should only trigger once
_{unless it triggers faster than the user variable changes...}

[gschmidt]

First time for me creating a user variable.
Don't exactly know where and how to create this.
I guess a LUA script type user variable?

When I paste this into the LUA editor, it says : [29:5] <expression> expected near ' [ '

Code: Select all

If [ [ [Bel Schakelaar] = [On] ] and [ [var Deurbel] = ["niet aangebeld"] ] ]
Do [Set [var Deurbel] = ["er is aangebeld"] ]
   [Send email]
   [Set [var Deurbel] = ["niet aangebeld"] after [10] seconds]

[tozzke]

it was just a blockly in text...

[gschmidt]

But to use in blocky a user variable I need to create it first before I can add it as a block is it?

[gschmidt]

I have created a User Variable Deurbel ["Niet aangebeld","Er is aangebeld"] in **/#/UserVariables (see picture)
And a blockly script as you suggested (blockly picture)
Although de "Deurbel Schakelaar" is set to ON, the script is not activated (according to the Log)

What I don't understand is how does the blockly script knows that "var Deurbel" is default set to "Niet Aangebeld"?
I just typed the text "Niet Aangebeld" en "Er is aangebeld" in a text field....???

[gschmidt]

Hmmm think I figured it out...I first have to set "var Deurbel".
So I added it to the blockly script that triggers "Bel Schakelaar"
This appears to work

But isn't there a way to set "var Deurbel" to "Niet aangebeld" by default?

[gschmidt]

Nope not working....I need to set the variable value to "Niet aangebeld" before the (physical button) "Deurbel" is pushed, otherwise the blockly script is setting the variable again to "Niet aangebeld" and sends an e-mail again.....arggghhhh

[tozzke]

Of course you'll have to do that, else the if condition won't be true. Where you can create the variables you can also give it a certain value 'Niet aangebeld' in this case.

Code: Select all

If [ [ [Bel Schakelaar] = [On] ] and [ [var Deurbel] = ["Niet aangebeld"] ] ]
Do [Set [var Deurbel] = ["Er is aangebeld"] ]
   [Send email]
   [Set [Bel Schakelaar] = [Off] after [3] seconds]
   [Set [var Deurbel] = ["Niet aangebeld"] after [10] seconds]

The time after which the switch has to go off again has to be shorter than the time for the variable, else the condition might be true again because of a small overlap.
I didn't know the 'Bel Schakelaar' didn't go to 'Off' after being pressed... You can also set an Off delay on the switch itself so it'll go off automatically after switched on.

I think I confused you a bit:

I have a doorbell learned in domoticz as (Deurbel). This showed not up as an ON/OFF switch but is shown in domoticz as

when the bell button at the frontdoor is pressed 1 time, domoticz log shows in a very short time 3 x a notification (sometimes 4 or 5):

Code: Select all

2019-02-10 11:44:04.926 (RFXtrx433XL) Lighting 4 (Deurbel)
2019-02-10 11:44:04.935 (RFXtrx433XL) Lighting 4 (Deurbel)
2019-02-10 11:44:04.949 (RFXtrx433XL) Lighting 4 (Deurbel)

Now I could add a (e-mail) notification to Deurbel, but I don't want >3 notifications.
So as a workaround I created a dummy ON/OFF switch "Bel Schakelaar". And use the "Bel Schakelaar" for the notifications.
In blockly I created a 1st script which sets "Bel Schakelaar" to ON when Deurbel is pressed at the frontdoor.

But this blockly script is also triggered 3 times, although "Bel Schakelaar" is already set to ON

So I understand your suggestion to add a variable. This is the script you suggested:

But this script is not triggered, and I have created a variable "Deurbel" with value "Niet aangebeld"
So I really don't know what I am missing here??

And this script won't trigger because you're using the wrong If-blockly... If you're only using 1 If statement, you'll have to use the If-blockly WITHOUT the blue gear icon on the top left

[gschmidt]

Yep...I also figured out...I modified a script and forgot to change
Now its working, Thanx man!

Just had some similair problems before..
just for asking, are you using a full 3v battery in your doorbell?
When the battery is almost empty, it also sends a lot of rf in the air wich also mess up the noise and spectrum in the 433 area when someone push the doorbell....
I did a rf scan @433.92mhz wich leads me to my old doorbell with a empty battery, when some pushes the knob, it was sending 9 times a signal.
In that time there was no nothing possible on the 433 band because the doorbell "hangs" for 15! seconds and domoticz recieved 9 times a "on" signal.
After replaced the battery everything was normal again.

Ps, i really started to hate the 433 stuff because of its lacky and bad signals...
