Did you buy a Fibaro keyfob has it fallen to pieces? well this might interest you. A eight keys keyfob ip68 rated

[clivec]

Hi fellow mysensors people
I have been working on a project , might need a bit of guidance to finish this off (with the sketch)
Ok lets start with what I have been doing , plus some researching

Right who of you purchased Fibaro_keyfob ??? that very reliable and ruggedized key fob
well yes I did too , it was approx. 45 pounds how long did it last ?? hmm 12 months or so
you also need a Aeotec_z-stick_gen5 to link it to domoticz .

It might look nice,, but really in my option was not fit for purpose poor design
at high price !!!.
The Fibaro you have to use a large coin to open and replace the battery ,,,,the connectors inside well weak!! not long and its buggered .. oh I’ll go and buy another at 45 ponds naaaaa!!!!
rinse and repeat every 12 months or so naaaa!!!!
you also needed a Aeotec_z-stick_gen5 to connect to domoitcz. As said.

Why would I do this since nowhere days we have voice control etc..
well for me it’s a universal way of switching off quite few things at once etc,,

So what was the alternative’s ???? ok
Well firstly most key fobs I have found are only 4 keys I wanted few more than that
in the end I came up with the key fob in first picture a ( rf solutions) key fob ip68 rated helpful might last past 12 months ,ok , now at this point I thought oh err use rflink to pick up signals job done But naaa it does not sense them , so if you want try this then rflick is not ganna cut it unfortunately .
So then you need its receiver module ie ..>>>
Telemetry module that in my case at 443mz frequency . be sure to get a receiver module that matches the key fobs transmitting frequency ( I did not need to tell you that did I )
Ok so the second picture is of the receiver module really not that hard really!!! .
My soldering will just about passes put quite a few caps in to stabilise the power as best as possible .
As you can see the telemetry modules are on the left and the mysensors (2) on the right .
I picked up a program from another project and modified it so that hopefully it would pick up four inputs on each unit
mini pro The sketch presented here is the modified sketch with 4 inputs
but one input works and the other inputs are temperamental
any suggestions or guidance for interfacing this with modules would be nice .

** Oh these receiver units like 3.6 volts so keep the voltage down
roughly 33 quid for key fob
11 pounds for each receiver unit ,,,you will need 2 for the eight key fob unit

@mutantx
I am seeming to have problems with the sketch ,heres is the modified sketch any guidance appreciated .

Update !!!! all fixed and working with domoticz
I used FOBBER-8T8 please google it approx. 20 quid compared to 45 pounds for fibaro keyfob
A) updated the sketch to allow 4 inputs s all fine
B) Symmetric really so from the top two pictures from the left the telemetry modules on the Vero board (total of 8 outputs ) passed across to two mysensors modules with 4 inputs on each unit I used 4016 cmos switches to pair outputs with inputs and It worked !!! .
So the ip 68 keyfob transmits to the telemetry modules which then output to the inputs of the sensors that
domoticz can pick up . add to blocky script can do what you want
Any help with This would be much applicated

And here's the completed unit I have not really tested the range yet ,
but should be good , the receiver units (telemetry units) can work in latching mode and in push button mode easy
I am pretty sure this setup will last longer than fibrio key fob , easy to pair receiver with key fob
I have 3 key fobs ,, yes why ??? well they will break and I rather purchase few ,for an investment for the future

Maybe some can help me with other project the stamp m5 pico trying to program it is a standard switch node
