Motion sensor "crashing" other sensors

[Nalith]

Hi

I am having a strange issue where my multi-sensor device seems to stop checking my DHT22 sensor values (TEMP and HUM) when the I set the motion sensors interrupt mode to CHANGE ("motion.setInterruptMode(CHANGE);". The unit does not actually freeze as the interrupt sensors still work but the battery and DHT22 sensor just seem to stop reading and sending data through. I have even tried specifically setting the setReportIntervalMinutes value on each of the sensors. When I set the setInterruptMode back to default then this problem seems to go away. I have lowered all timeouts and sleep intervals for testing.

Below are the logs:

Thanks for reporting this issue, I'll try to reproduce and I'll come back to you should I have any further question.

[Nalith]

Thanks. Love the NodeManager solution btw. I have logged a post of the mysensors forum (https://forum.mysensors.org/topic/9873/nodemanager-motion-door-interrupt-sensor-stopping-dht22-from-reading-value-after-a-while) with my source code, should I close that thread?

[Nalith]

Some more additional information, if I add setReportIntervalMinutes after nodeManager.loop() it seems to sort out the problem, been running for 12 hours without any issue, will keen an eye on it and update you accordingly.

[user2684]

Hi, feel free to keep the thread on the forum there, somebody could always come out with a solution, who knows :) Can you share the sketch you are using? I'll try to reproduce it tomorrow. Thanks!

[Nalith]

I have attached a copy of the sketch that I was having a issue with:

My Setup:

• Arduino Pro Mini 3.3v
• HC-SR501 Passive Infrared Sensor (PIR) (PIN 2)
• Reed Switch for Door Sensor (PIN 3)
• DHT22 Temp/Hum Sensor (PIN 4)
• DS1302 Real Time Clock (As a test)
• NRF24L01+ with Capacitors
• MySensors 2.3.0 release
• NodeManager (Latest Development Branch)
• Home Assistant (Controller)

If you toggle the door sensor a couple of times or have the motion sensor go off a couple of times it will eventually stop running the DHT sensor loop. Interrupts still work fine but not the stuff that is timer based if that makes sense?

Test.zip

[user2684]

I think the issue is related to an interrupt-based sensor combined with other sensors reporting periodically on a sleeping board. The thing is, every time an interrupt occurs, there is no way without being time-aware to know how much time has been spent on sleeping which may lead to these situations. However, I see you are using an RTC which is also enabled on your sketch but I cannot see any log related to it. Any chance sharing the logs while using the RTC? thanks

[Nalith]

Thanks for the effort you are putting into assisting with this. I had eventually tried adding a RTC to see if that resolved the problem however it did not, all that it did was rectify the sleep time so it resumes sleep for only the remaining time and not from the original sleep time.

I have since used a different Arduino Pro Mini board only connecting a DHT22 sensor and a push button to simulate the door switch, the report and sleep interval have been configured to 30 seconds for testing. The loop works correctly without any issues however as soon as I toggle the door sensor a few times while its sleeping it seems to forget that there is a door sensor connected and does not execute the DHT22 loop when it executes the NodeManager loop (See line 116/117 in log files). I had initially thought if I reset the report at the end of the loop however it does not seem to resolve the issue. It's almost as if NodeManager internally forgets that there is a DHT22 sensor attached and just does an empty loop, all interrupts still work like a charm. A single open/close during the sleep cycle seems to work however if there are q few consecutive interrupts it seems to break. Please find attached the source + log. Let me know if you need any additional info.

Apologies, just noticed you had asked for logs/source code for when I was using the RTC module, I have already removed that from my sketch as it did not resolve the issue but could wire it back up and send through the logs if it would help resolve the issue. Please let me know if the sketch + logs sent through are not sufficient?

[user2684]

@Nalith sorry for the delay, I was finally able to find some time to run a similar test but unfortunately I couldn't reproduce the issue. I had a DHT22 sensor and a motion sensor with a configuration similar to yours. I started without power manager first and got this:

So as you can see it is working but the humidity was missing in this case. This is because there is a isnan() test in Child::_setValueNumber() and a DHT sensor if unable to poll a measure returns nan. My guess is it has something to do with power manager, maybe 1s of sleep before polling the sensor is not enough (which is anyhow weird since we sleep for getMinimumSamplingPeriod() before invoking readSensor() in the DHT class).
I'll keep this open as a bug but outside the v1.8 queue for now.
Thanks!

Thanks for all your help, will keep you posted too if I manage to narrow it down more.

Have not managed to narrow this down and don't seem to be getting the issue anymore so will close this bug for now.
