Low cost window/door sensor

[Papou]

Bonjour;
Je viens de recevoir deux de ces capteurs, ils ont un peu changé.
Il suffit de faire des ponts de soudures pour le 3M3 les autres sont présents, mais ce sont les mêmes pour les deux capteurs.
J'en ai customisé un pour ma boites à lettres, il m'a suffit de déporter le capteur ILS avec deux fils, et de placer l'aimant sans son boitier. Je ne peux pas faire la distinction entre une lettre et un colis.

Hello;
I just received two of these sensors, they have changed a little.
Just make solder bridges for 3M3 others are present, but it is the same for both sensors.
I have one for my customized mailboxes, it was enough to deport the reed sensor with two son, and place the magnet without its box. I can not distinguish between a letter and a package.

Pour terminer, voci deux photos de ma boite à lettres, le capteur le long de la porte qui assure, avec l'aimant collé sur le volet, l'ouverture de ce dernier pour les lettres et l'ouverture de la porte pour les colis.
Le boitier émetteur est situé au fond pour ne pas gêner, le fond de la boite est percé pour le passage de l'antenne. le RFXCOM 433E est situé dans le grenier d'une maison à un étage, et la liaison radio passe très bien.
Finally, here are two pictures of my mail box, the sensor along the door that ensures, with the magnet glued on the flap, opening it for letters and opening the door for parcels .
The transmission box is located at the bottom to avoid hampering the bottom of the box is pierced for the passage of the antenna. RFXCOM the 433E is located in the attic of a one-story house, and the radio link going very well.

The Oudi sensor looks nice. Did you have any problems with the range? And what protocol to select in RFXcom?

I was thinking of putting one into my mailbox which is 110 meters away. It didn't work so the range is shorter than this. I'd say 50 meters is the maximum, but your mileage may vary. The ones I have on the front door and on the back door work fine. The OUDI AD-87 sensor uses Lighting 4 protocol.

Hi there,

I also ordered some OUDI AD-87. But, till now I can't get them connected to Domoticz. I use a rfxcom433e with 250 (=latest) firmware.

@Jarvis: Can you explain how you got these door sensor added to Domoticz?

I've enabled the following protocols:

I have 248 firmware on my RFXtrx433E. For me adding the sensors was very straightforward, no tricks, no hacks, they just work.

Hi,
First of all: n00b Domoticz enthousiast here . I bought a couple of cheap Chinese detectors (http://www.aliexpress.com/item/433mhz-d ... 64628.html, but can't get them to work with the RFXCOM 433E. Other switches (Eurodomest) are working fine. The Chinese detectors have a EV1527/1542 chipset. According to other posts this should be working with the RFXCOM. I checked the battery: full.

I have used RFXmngr with 'undec on' checked to view the communication, but no signal at all from the detectors. I tried some 'jumper' settings, but no luck. The detector is being activated (the led flashes), but the RFXCOM remains silent
See the front and backside of the detectors below:



Please advise! What am I missing here? Any help much appreciated!

The RFXtrx433E will receive the Lighting4 protocol with total pulse length of about 1400ms.
If you have ordered the PT2262 select or mount the 3M3 oscillator resistor.
Not tested: the EV1527 needs a 300K oscillator resistor.

[Niels]

Hmm, 1.5, 3.3, 4.7 M Ohm are the standard options (jumpers) if I get it right . Replacing this by a 300k Ohm would do the trick?

Hi, Can anyone help me.
I bough a few of those:

They only send a "OFF" command I cant make them sen an "ON"command.
The PCB is really simplified, it has no jumpers and a EV1527 chip.
What do I have to do to make them send an "ON"command, I don't need both, just "ON"

Thanks

I ordered a smoke sensor from Alixpress but I can't find the oscillator resistor or any jumper in the one I received.

Can you help me, please?

This is the RF PCB for one I received:

[b_weijenberg]

The oscillator resister is connected between pin 15 and 16. This is R6 on your PCB.

[Niels]

Same question for me: the PCB seems to be suitable for both the PT2262 and the EV1527 chipset. I tried to connect the 300K Ohm resistor (see this post) in R4/R5 buth that location seems to be connected to the PT2262 pinholes, not the EV1527. Where should I place the resistor?

Regards,
Niels

Contact support rfxcom.com for a beta version firmware that should be able to receive these and Chuango.

You've got mail [THUMBS UP SIGN]

[Niels]

Rfxcom mailed me a beta version of the firmware: problem solved! Firmware will be available soon. Thanks for the great support b_weijenberg!

Just as follow up for others interested in the same information in the future:

There are solder pads to sellect the resistor at the back of the PCB covered by a double side foam tape, somehow hard to see

Now it working great!

[nathanashton]

I ended up purchasing 4 of the sensors shown in the original post with the PT2262 chip. They only seem to send an OFF signal when they are separated. I wanted to use these to show if a door (or sliding door) is open or closed. It seems I cant do this as there is no event for when the sensor is Closed again.

Anyone have any suggestion on what else I could use them for?

Cheers

Hi,

First of all...thanks a lot for all the information on this forum and this thread in specific. I ordered some of these motion detectors and door contacts and they are working, more or less. The same seller also sells a generic 433 MHz keyfob (remote) with four buttons (http://www.ebay.nl/itm/180775159982?_tr ... EBIDX%3AIT) and it's also working in Domoticz. Not sure what to do with it yet, but I will think of something

However, I'm still trying to figure out how to use these door contacts...As suggested in this thread, they do NOT send an open/closed state, but only an on or off signal (depending on jumper settings) when opened? And if I want to have a contact that sends it's state, I should go with the KAKU versions?

A good thing about these contacts...they are quite 'forgiving' in the distance between sensor and magnet. They don't have to be as close as other contacts, which is easier fixing on older doors.

The motion sensors will be used as a secondary alarm system. We have a certified system installed, but it might be nice to have something less 'strict' and more flexible, for example when working in the garden or in the garage.

Grtz,
Johan

How did you do this ? you have a screenshot of the settings ?

I have 1 PIR sending an On command when movement detected and another one sending Off when movement detected.

So i found some other ON codes

only yellow: ARC P16 ON
yellow + orange: ARC P8 ON
yellow + green: ARC P12 ON
yellow + blue: ARC P14 ON
yellow + gray: ARC P15 ON

**ignore the jumpers, old settings not working. distance only 3.3m**

Hmm strange. When I follow your instructions with only yellow I get an OFF code:
Lighting 1 ARC Off 7

Now my question is how I can trigger this motion sensor to turn on the light in my toilet? I tried to put this in an Event but it doesn't work:

Whether the low cost sensors send an On of Off command depends on the jumper settings. I have 1 PIR sending an On command when movement detected and another one sending Off when movement detected.
So, in your Blocky, you should set if Bewegingssensor = Off then Toilet spot On. Seems a bit strange, but it just depends on the jumper.

I also ordered the Oudi door sensor. But when I add it as a switch it only turn on, and never gets off (also won't turn off when I click it by hand). Should I change it to another type of switch?
