Low cost window/door sensor

[SweetPants]

Commands seem to be sent 3 times each.

Which can cause issues (collisions) with other devices sending at the same time.

Anyone with a link to working on AND off sensors with RFLink please?

[SweetPants]

AMST606 (KaKu) sends both on/and off and work with RFLink. But they also send long signals which may interfere with other signals

I have purchased the sensors below and can't get them to work with RFXCOM I've tried Lighting4 and ARC. It does say on the listing that the oscillator resistor can be 330K, any ideas where to put it ? Is it the empty space where it says R5 or maybe the 4 headers GTRV ? The chip markings is STC15W101.

Thanks in advance

Did you try to disable all other protocols on your rfxcom when pairing these devices?
WIth mine it worked that way, apparently there were protocols interfering or somethiing.

AFter pairing you can enale the other protocols again.

Thanks ArieKanarie, that got them recognised but it detected 6 devices - 2 for each of the tamper, closed and open.

But it only works intermittently and not consistently between the 2 pairs. I tried it in RFXmngr (see below for example only tamper output) and same occurs, it is recognised but only 1 in approx 20 actions and varies between the 2 outputs.

Did notice the pulse is 458usec is this correct ? thought it needed to be 350. Do I need to change this with a resistor and where do I add it ?

Cheers

Interestingly, if I enable X10 at same time as Lighting4 I get this output, again, intermittently:

subtype = X10 security
Sequence nbr = 36

ON DOOR OPEN:

Sequence nbr = 37

status = Alarm
battery level = Low
Signal level = 7 -64dBm

ON TAMPER:

id1-3 = BCF900 decimal:12384512
status = Alarm
battery level = OK
Signal level = 7 -64dBm

Spotted another setting "undec on". If I have this and ARC on, it responds to every event but varies between 3-7 codes:

ON DOOR CLOSE:
Packettype = UNDECODED RF Message

I finally received mine, they work perfect, at least 3 of them, the other 2 won't be recognised.
Strangely I had that same problem with my previous sensors, which after sending them to rfxcom and back worked without any changes. So going to try them later again.

Since when are those sensors/switches automaticly added as security device, no matter wat device I suggest when pairing?
Now I cannot change the picture anymore, and for my old sensors (only on signal) I miss the on and off delay?

Hi,
I bought a DS-4 V1.0 low cost door sensor from Aliexpress, and now get it working as it should in Domoticz (openmediavault plugin) + RFLINK (R45 firmware).
I posted a video on how to proceed:

if that helps.

[Derik]

did buy yourself a Xiaomi smarthome sensor..
Works great and is very smal/nice....
No mods needed, just install en working for months on a battery...

You need a bridge..

[svenalkalaj]

Hi,
Could you be more specific :
- what frequency is this device using (433Mhz?)?
- what type of device is OK with xiaomi ? RFXCOM or RFLINK?

What do you mean by you need a bridge ?

Thanks.

[Derik]

mmm
Sorry is gateway .. iso bridge

Search the forum for xiaomi

[svenalkalaj]

OK, looks good, but for people who already have a low cost rflink (homemade with prototyping pcb and chinese arduino reflashed), the gateway price could be a killer.

~30€ only for a gateway to control xiaomi devices, when with a cheap rflink you can interact with much more devices brands...

However, designwise xiaomi is much more interesting.

I am wondering if there is any way around this.

Yes. Disabling de X10 protocol beore pairing.
If lucky (like in my case) the sensors will be paired with another protocol.

Nice if you had said that the unused sensor1 may not be revoked, spend an hour to find out

Hi there,

I'm also looking for a cheap and compact door sensor that I can use with the RFXTRX433 - as there a lot of uncertainties and unsupported devices in the discussion; can anyone suggest one from Aliexpress that supports Open/Close signals?

Thanks a lot for your help

[b_weijenberg]

The Kerui D026 is supported, enable Lighting4 + X10 and the sensor is received as X10 security sensor.

[chbla]

Does it support Open AND Close? The Kerui seem to be rather expensive

Otherwise I found which were posted in the video above, they work too I assume.

https://de.aliexpress.com/item/5pcs-433 ... Title=true

These would be cheaper, first two use a coin cell:

https://de.aliexpress.com/item/3pcs-hot ... autifyAB=0
(Edit: sends only Open, according to the seller)

https://de.aliexpress.com/item/5pcs-Mar ... autifyAB=0
(Edit: sends only Open, according to the seller)

https://de.aliexpress.com/item/5pcs-Mar ... autifyAB=0
(Edit: sends only Open, according to the seller)

But no word about open/close support..
