Gas Meter
-
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 shieldData 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: TSP:MSG:BC 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.
