Ok, I was thinking that I could ask the state of the message S_LIGHT at every wake up,
and if it changes, do my IR sending ...
But it seems to not work.
I guess for this, the problem is on the controller side, after send the command, without acknowledge , it give up and let the state of the button unchanged.

Always on means power supply, This sensor must also get temperature, so I don't want to put it anywhere ...

anyway thanks for you help

Yes I know that for sleep mode,
I also choose the relay sample to test purpose, I will not put a relay !
Instead of switching a relay on or off, I want to send an IR code.

Because I'm running on batterys, I do not want my node to always call gw.process() ! It will drain the battery quite full !

That's why I was trying to do :

void loop(){
gw.process();
gw.sleep(10000); //10s sleep
}

and what I was expecting :
if a message was send from my controlelr (jeedom) during the sleep time,
the gw.process() will retrive this missing message ... but it doesn't.

How to do such function ? (save battery and receive message, even asynchronously)

Thanks.

Hi all !

First message here !
I'm very enjoing play with mysensors to build my own Home Automation devices !

I have a question about creating a node powered on battery and sending IR codes !

That means, I would like my sensor sleep for a while, and they get the status of the message.
I don't need in this case a fast responce (few seconds is ok here).

So First, I take the sample of the Relay, add a gw.sleep(10000) after process...
but it doesn't work : after the sleep, the message was not received. (If I change state from my controller)
I also try to reduce to 1s, but it's the same
after gw.process, I try to call
digitalWrite(RELAY_1, gw.loadState(1)?RELAY_ON:RELAY_OFF);
same here : the state was not received

Someone has a idea to do this ?
(I mean receive a message from Gateway and sleep to keep battery) ?

Kytrix.
