different information

[Barna]

Hi,
Could you help me, what the problem is ?
The log and detailed data time-stamps are not some.
LOG:
2017-12-09 22:27:01.131 (mysensor_gate) Temp + Humidity (Udvar)
2017-12-09 22:27:01.131 (mysensor_gate) Temp + Humidity (Udvar)

2017-12-09 22:57:03.681 (mysensor_gate) Temp + Humidity (Udvar)

2017-12-09 23:05:00 56 0.8
2017-12-09 23:10:00 56 0.8

code:
unsigned long SLEEP_TIME = 900000;
send(msgTemp.set(DHT.temperature, 1));
send(msgHum.set(DHT.humidity, 1));
delay(SLEEP_TIME);

The node must send data by 15min, Domonicz receives it by 30min, detailed data contains 5min data.
Does the Domonicz feel 30min gap every 5min ?

thanks

@barna Domoticz always saves the data in 5 minutes summaries, regardless of at which frequency it is actually received.

I'm not sure I understand the part "Domonicz receives it by 30min". Regardless of what is finally stored, you should still see the values in the devices displayed correctly when a new data point arrives.

[Barna]

The 5min summaries was new for me, thanks the info.
But I do not understand if the node wakes up in every 15min, why the Domonicz receives data only by 30min only.

[manutremo]

@barna In order to do understand that we'd need to see the node and gateway logs, and the full sketch.

[Barna]

I have checked the node log, the Domonicz is correct, the node sends message every 30min, but why if 900000 = 15min ?

@barna I just noticed you are using delay() for the wait. It is recommended to use the mysensors function wait() instead of delay().

See here.

If using wait() doesn't fix it, the only option I can think of at this moment is if you were using a 8Mhz board but compiled the program for a 16MHz...

[Barna]

I have replaced the delay() by sleep() and every problem was resolved :)

[manutremo]

Yes, sleep is the equivalent to wait if you want to put the arduino to sleep. If it fixed it, wait should too.
