Hi,
Thanks for feedback, I'll try code from alowhum first.

@alowhum
Thanks for the input and example.
I'll test your code now.

@alowhum
yes, tried to use loops but no luck so far.

I have one loop with viarable

#define NUMBER_OF_RELAYS 8 // Total number of attached relays

which then is used

void before() { 
  for (int sensor=1, pin=RELAY_0; sensor<=NUMBER_OF_RELAYS;sensor++, pin++) {
    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);   
    // Set relay to last known state (using eeprom storage) 
    digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);
  }
}

but how to use it i.e. for

Bounce debouncer

Maybe you can explain.
Thanks

@mfalkvidd said in Help to optimize my sketch:

maintainability

Hi,
yes, I'd like to optimize readability/maintainability of that code. RAM or flash size does not mater currently.
I want to learn more how to use loops and #define parameters for more transparency.

Hi,

I've wrote some bad code and I'm sure that someone here can help me to optimize it. I'm still begginer.

Goal:

Serial gateway for Domoticz system without any wireless nodes
running on Arduino Mega 2560
8 relays with digital input buttons
8 digital input for door contact (currently 3 implemented)
temperature sensord on 1 wire in future

Hi,

I'm working on gas meter using In-Z61 reed sensor - it's dedicated for gas meters.

My node is build based on https://www.mysensors.org/hardware/ac-dc-ssd-relay
My controller is Domo: v3.8258
My gateway is Arduino UNO shield

Data is send over to Domo as designed
One full rotare of gas meter 00.000 [m3] -> 00.010 [m3] is one impuls triggered by reed sensor.

This is working - after one rotare i got value send to Domo:

The issue is that after some while the counter still increments - no actual meter movement is done
Below is debug - pulse was 100 and was changed to 101.

pulsecount:100
TSP:MSG:SEND 8-8-0-0 s=1,c=1,t=24,pt=5,l=4,sg=0,ft=0,st=ok:100
volume:0.100
TSP:MSG:SEND 8-8-0-0 s=1,c=1,t=35,pt=7,l=5,sg=0,ft=0,st=ok:0.100
TSP:MSG:READ 7-7-255 s=255,c=3,t=7,pt=0,l=0,sg=0:
TSP:MSG:BC
TSP:MSG:READ 7-7-255 s=255,c=3,t=7,pt=0,l=0,sg=0:

l/min:0.03
TSP:MSG:SEND 8-8-0-0 s=1,c=1,t=34,pt=7,l=5,sg=0,ft=0,st=ok:0.03
pulsecount:101
TSP:MSG:SEND 8-8-0-0 s=1,c=1,t=24,pt=5,l=4,sg=0,ft=0,st=ok:101
volume:0.101
TSP:MSG:SEND 8-8-0-0 s=1,c=1,t=35,pt=7,l=5,sg=0,ft=0,st=ok:0.101
TSP:MSG:READ 7-7-255 s=255,c=3,t=7,pt=0,l=0,sg=0:
TSP:MSG:BC
pulsecount:101

As a sketch I use modified version of PulseWaterMeter - https://www.mysensors.org/build/pulse_water

I changed presentation:

 present(CHILD_ID, S_GAS);

and added node temp sensor:

present(CHILD_DSB_ID, S_TEMP);

It looks like some kind of bouncing effect, but have no idea why counter increments itself.

Help me out to make the code more clear and free of errors.

code below:

 *
 * DESCRIPTION
 * Use this sensor to measure volume and flow of your house watermeter.
 * You need to set the correct pulsefactor of your meter (pulses per m3).
 * The sensor starts by fetching current volume reading from gateway (VAR 1).
 * Reports both volume and flow back to gateway.
 *
 * Unfortunately millis() won't increment when the Arduino is in
 * sleepmode. So we cannot make this sensor sleep if we also want
 * to calculate/report flow.

 * DESCRIPTION
 * Use this sensor to measure volume and flow of your house watermeter.
 * You need to set the correct pulsefactor of your meter (pulses per m3).
 * The sensor starts by fetching current volume reading from gateway (VAR 1).
 * Reports both volume and flow back to gateway.
 *
 * Unfortunately millis() won't increment when the Arduino is in
 * sleepmode. So we cannot make this sensor sleep if we also want
 * to calculate/report flow.

Hi,

so my node is sending data every 3 seconds

TSP:MSG:SEND 7-7-0-0 s=1,c=1,t=24,pt=5,l=4,sg=0,ft=0,st=ok:2
volume:0.002
TSP:MSG:SEND 7-7-0-0 s=1,c=1,t=35,pt=7,l=5,sg=0,ft=0,st=ok:0.002

Domoticz see the updated vaule, but not in Devices

Debug looks perfect..., but cannot see the node in Domoticz i Devices tab
I can see the node under Hardware -> MySensorsGateway only:

I want to test gas meter IN-Z61.
