Relay and Light Node

Marek Běluša

Hi, i try to combine Relay and Light node sketch. It works ok but i need put interupt or delay for light sensor reading only 1 read per minute. If i put sleep time to loop then it block comunication for realy and node repeater :-(

I found some examples only for 1.5 v nodes .........

Thanks for help!

My sketch:

/**

The MySensors Arduino library handles the wireless radio link and protocol
between your home built sensors/actuators and HA controller of choice.
The sensors forms a self healing radio network with optional repeaters. Each
repeater and gateway builds a routing tables in EEPROM which keeps track of the
network topology allowing messages to be routed to nodes.

Hi Marek,
What I've done in this situation is to introduce a time check instead of sleeping the node, since you need to keep it awake to listen for relay commands. I got my inspiration from Hek's RGB dimmer sketch.

My code was for a gas sensor:

unsigned long currentTime  = millis();
if (currentTime > lastTime + READ_DELAY_TIME) {
    lastTime = currentTime;
    readgassensor();
  }

READ_DELAY_TIME is set to 30000 so that it waits 30s between reads (in your case, increase that to get 1min intervals).

This is not a super-precise way of doing it, but it's simple enough for regular sensor reads and seems to work for me.

Hope that helps!

Hi!

Thanks for help, now it works perfect :-)
