How to configure cheap sensors with PT2262

Postby b_weijenberg » Wednesday 27 January 2016 14:16

The RFXtrx433 and RFXtrx433E transceivers are able to receive the PT2262.
The 3M3 oscillator resistor must be selected.

The PT2262 packets can be received in Lighting4 as a bit pattern but can also be received as an ARC On or Off packet if the PT2262 pins are configured as follows:
L=Low,
F=Floating (not connected),
H=High (not used)

Code: Select all

Bert, is there a way to influence 'update frequency' with the PT2262? That is: I want to hook this up to a wireless moisture sensor, but I hate changing batteries and readings are needed < 2 times a day...

Thx again for Rfxcom: love the product. And on a side note: I get a LOT of readings from someone in my neighborhood. And the moment I see a PT2262 device that isn;t mine, I know he will likely have an Rfxcom too. That means I'm less and less inclined to use 433Mhz for control devices, but still a great fan of using it for sensor applications. I don't mind other folks reading my sensors, but I hate for others to control my lighting, shutters etc.!

If the PIR or contact is triggered the PT2262 will transmit a few packets.
If the PT2262 is not triggered it will not send an RF packet.

The RFXtrx433(E) accepts a wider range of PT2262 and EV1527 pulse timing starting at firmware version 1001 released Feb 18,2016.

Bert,

I just updated my Domoticz and to my big suprise i have a new device, unknown to me
RFXcom433E 904014 0 Unknown Lighting 4 PT2262 On - 2016-08-15 23:15:08
As you might remember, i'm the one with the SEAV sunscreens, so i was hoping it might be one of them, but when i looked further i found a Byron SX Chime (the sunscreen) and the timestamp it's completely wrong between them
RFXcom433E 0055 6 Unknown Chime ByronSX On 7 2016-08-15 18:43:35

Is there any (easy way) to figure out who's and what device it is?
(i already stood in the garden clicking on the on/off button and listening in the hope i would hear someone curse his pants off, but no luck) *grin*

With Lighting4 and "Accept new Hardware Devices" enabled you have a high risk to receive many unknown devices because the PT2262 and compatibles don't have a check on valid packets.
For normal use it is advised to disable "Accept new Hardware Devices"

Ok, turning it off.
Thanks
