Low cost window/door sensor

I got this PIR (http://www.aliexpress.com/item/Big-sale ... 91232.html)before I found this topic. It shows up in Domoticz straight away as PT2262, Lighting 4. However I can't find a pt2262 chip.

Lucky me I guess.

Maybe the PT2262 is on the other side of the PCB.

No, the other side is empty.

What is written on the small black chip with 8 legs? Maybe thats the transmitter... The big one (BISS...) is only for the detection part i thought.

that would be an EV1527 ...
This PIR is supported by the rflink gateway

That would be possible. I see a lot of references to the PT2262 when i search for 'EV1527' on Google.

This sensor does not have a PT2262 but the EV1527 (U6) which produces a PT2262 compatible signal.
The oscillator resistor connected to pin 1 has the correct value for the RFXtrx433(E) - Lighting4.

The small chip says SC1527.
So can we start shopping for EV1527 sensors?
Would they have different domoticz/RFXcom ID's, because there are no jumper pins?

The following IC's are compatible: EV1527, FP1527, HS1527, RT1527 and SC1527
Each device has a fixed (different) 20 bits ID.

Hi !

Do you know if these products : http://fr.aliexpress.com/item/New-White ... 64623.html are working with a RFXCom 433 ?

Thx by advance !

The indication is EV-1527 so I suppose they will be received with Lighting4.
If not you have to change the oscillator resistor connected to pin 1 for a pulse width of 350usec

They look like the ones I have. They work but only send one signal when the magnet opens or closes the reed switch. So they only send an on OR off signal, so not like the Fibaro sensor which reports an open state (magnet away reed contact closed) or a closed state (magnet keeps the reed switch open).
Also they send a quite long signal (burst).
Besides that they work fine.

Thanks for the interesting information roblom !
With this operation, do you have succed to have "windows open"/"window closed" status ? maybe with a script ?

Thx !

If these sensors only send a signal when the door is opened, how would you know when the door is closed? The only way to know that it is closed is when you open the door again, then you know that it was closed, but not when.
You can also try the AMST606 (KAKU), they send Open/Closed commands.

That's what I tried to tell, getting the status is not possible because you only get a signal at changes and there is only one type of signal.
I used it to get a notification when the lid of the mailbox was opened so I knew when there was mail delivered.
The problem was that I have also soil sensors on the imagitronic protocol and this protocol blocks the lightning4 protocol (or the other way around as you wish) where these contact sensors work on. So I replaced the cheap sensor for a kaku door contact (a bit less cheap

).

Hummm ok ... do you have a great online merchant to buy it from france ? I only see it about 15€.... do you have great adress for it less cheaper maybe ?

For the kaku you mean? €15 is a normal price for the kaku door contact. Just to be clear; the kaku also sends only one signal, so state detection is also not possible. I switched to the kaku because of the protocol.

Not true, I have all my windows equipped with AMST606 and when the window is open Domoticz says "Open" if closed it says "Closed"

Please discuss about KaKu and other doorcontacts in a separate (new?) topic. This topic is only for PT2262/EVxxxx contacts.

After more thinking you could be right. As I don't want to get multiple notifications I used the delay timer. But as the lid never stays open I never noticed it could also report the state.
But indeed let's stay on topic.
