Trying to use it like rcswitch-pi

[Pierre-Gilles]

Hi !

First of all thank you very much for your module :)

I'm trying to control my RF 433 Power Plugs with a Raspberry Pi and a 433Mhz emitter. It work fine with rcswitchPi, ( with the send function here : https://github.com/r10r/rcswitch-pi/blob/master/send.cpp ) and I would like to do the same with your module.

Problem : I need to send :
./send <systemCode> <unitCode> <command>

it look like that in real life :
./send 01111 4 1
( 01111 is the code of the plug, 4 is a second code ( A, B, C, or D corresponding to 1, 2, 3, 4 ), and 1 is for "On" )

Do you know how can I send such a code like in rcswitch-pi with your module ? Maybe it's very simple.

Thank you very much for your answer,

Hi Tom.

Firstly, I'll echo Pierre-Gilles' thank you; it's great that you are pushing this idea forward.

If I can figure this thing out, it'll be extremely useful to me.

I've tried out your PiSwitch as well as rcswitch-pi (in a couple of different forms), on a RPi with one of these; http://uk.rs-online.com/web/p/lower-power-rf-modules/6172072/ and some of these; http://www.maplin.co.uk/p/remote-controlled-mains-socket-set-single-n78ka (the sockets with the two rotary dials on the back), but I can't seem to get any of it to work.

Similarly to above, I believe it should operate using ./send 4 4 1 for example, but it seems seems not to be working at all.

Do you think that it might be a case of me using the wrong GPIO pin for the data, the wrong syntax for the command, or something else entirely?

What I really need is an Idiot's Guide type of thing for your implementation, as I have had to piece the complete method for this OOK controller from several sources on the web and they all have slightly different, or even conflicting methodologies, pin-outs and libraries in use, which is very confusing.

I'd ideally like to wire up a simple OOK sender to attach to my emonPi (http://openenergymonitor.org/emon/), in order to help to turn it into a home automation hub, as well as an energy monitor and emonCMS server, so any help in getting this thing working would be very much appreciated.

Thanks in advance for any information you can give me,

Rich.

@Pierre-Gilles: Is that the precise call you’re making to RCSwitchPi, i.e., switchOn("01111", 4) or ./send 01111 4 1 on the command line? I’m only familiar with the code schemas I list here, but the format is generally just a cosmetic thing. What kind of switches do your outlets have (compare with this wiki page)?

Looking at the RCSwitch code again, my guess is that this is a deprecated syntax for the 10 DIP switches type. In that case the equivalent PiSwitch call should be send('0111100010', 'dip') or node example 0111100010 dip for the example. Be sure to check the pulse length.

@R1CH-T: What’s the exact call you’re making to PiSwitch (or the CLI command for the example script)? Since you have the two rotary switches type, it should be send('44', 'rotary') / node example 44 rotary. And again, make sure your pulse length is set correctly.

If you’re not sure the whole thing works at all (as opposed to just not sending the right code), check with a LED in place of or in addition to the 433 MHz transmitter. It should flicker very quickly corresponding to the code being sent.

Thanks for the very quick response, Tom.
I'll review my methodology and report back.
I'll start from scratch and If and when I get it working, I'll make my notes into a how-to and link to it for you.

@tjanson I'm sending via the CLI ./send 01111 4 1. Thank you for the link, my plug model is exactly the "Type A: 10 pole DIP switches" !

I will try send('0111100010', 'dip') tonight, thank you for your help :)
