Cheap China Wall switches etc

First thank You for in my home the most used INDIGO plugin!

There is a small (simple?) thing that I deeply would like to be added RFXCOM Bluligin:

There are a lot off China made transmitters in price range 2 to 4 Euros/USD in eBay market. They are 433 and 315 MHz transmitters and receivers that most use EV1527 chip. They (i think) use Lightning4 protocol or close to it.
A good example is:

The chip itself has 4 channels (buttons) that send messages. EV 1527 is serialised whit one million individual numbers. Wall switches use 3 of those in 1-3-2 order from left to right. The center button (3) is recognised by current RFXTRX- plugin as an RFX Security sensor.:

ID: chips serial number ( one million different numbers ) or part of it.
TYPE: 32

Buttons 2 and 4 (if available) will not be praised, and they give unknown type error 19.

EXSAMPLE:

CENTER BUTTON:
>>>>>>>>>>>>>>
RFXCOM Debug processing: 8 32 0 29 61 170 240 2 105 (08 20 00 1D 3D AA F0 02 69)
RFXCOM Debug Security sensor 61501 of type 0 (X10 security door/window sensor) has status 2 (X10 alarm)
RFXCOM Debug Security sensor 61501 in list ](<<< Each unit have different number)[/b]

LEFT BUTTON:
>>>>>>>>>>>>>>
RFXCOM Debug processing: 9 19 0 18 61 170 244 1 40 96 (09 13 00 12 3D AA F4 01 28 60)
RFXCOM Error unknown device type detected (type = 19)

RIGHT BUTTON:
>>>>>>>>>>>>>>
RFXCOM Debug processing: 9 19 0 22 61 170 242 1 37 96 (09 13 00 16 3D AA F2 01 25 60)
RFXCOM Error unknown device type detected (type = 19)

So at the moment I can only use the mid (number 3) button as it is. It is possible to make a little soldering to get one button switches to act as mid button, but it would be nice to have all 3 or even all 4 buttons working.

a workout could also be a device type (xxx), that can be created based on incoming raw data. Example:

processing: 9 19 0 18 61 170 244 1 40 96 (09 13 00 12 3D AA F4 01 28 60) data will turn device type (xxx) on (and different data off)?
Or just toggle (xxx)

I believe that this economical solution would be in interest of most INDIGO users, as it would give a easy way of controlling home appliances at a marginal cost. Also, as RFXTRX can send commands, a sending option could also be possible. Again maybe just raw data. All those switches have a compatible learning code devices as relays or receiver- modules at a price tag of 0,50 cent to a few dollars.

Again, thank you what we already have, and I hope that this will be implemented in near future.
I will give all my help for whatever I can do: test, find compatible devices, send You samples etc...

Best Regards,

Re: Cheap China Wall switches etc

Ok,
Did some hacking, in the plugin - sorry-, made #19 device act as another item, that I will not need, and then trigger #32 security. Works ! Great.
