Troubleshooting

Hi @crazynight, welcome to the MySensors community! Seems like the node is unable to send messages to the gateway. If you are using the nrf24 radio, the cause of the communication problem is most likely insufficient/unstable power. If you haven't already, see https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common causes and how to troubleshoot them. It also contains a checklist of what information is most useful to post so people can assist you.

@strixx make sure you flash the correct bootloader for the crystal frequency of your pro mini (3.3V 8Mhz vs 5V 16MHz) and select the correct pro mini target in the Arduino IDE. Any errors will cause baudrate deviation in the serial bootloader communication, causing sync errors.

Well. It was the radio that caused this false triggers. The final placement of the node must be in a radio shaddow. I really "funny" thing is that I solved this problem by changing the radio. I had a NRF24L01+PA+LNA for better range. This was for future project (node in my greenhouse) which would need this node as a repeater for shore. But by replacing the radio to a "normal" NRF24L01+ made the problem go away. I did not change the location!

@mfalkvidd Hi, I manage to make an MQTT gateway with home assistant as controller . The serial from gateway i can see that the gateway send data out from MQTT, but the node still not receive anything 870503 TSF:MSG:READ,2-2-0,s=3,c=2,t=0,pt=0,l=0,sg=0: 870508 GWT:TPS:TOPIC=mygateway1-out/2/3/2/0/0,MSG SENT 870569 GWT:TPS:TOPIC=mygateway1-out/0/4/1/0/47,MSG SENT 870587 GWT:TPS:TOPIC=mygateway1-out/0/3/1/0/0,MSG SENT 871604 TSF:MSG:READ,2-2-0,s=3,c=2,t=0,pt=0,l=0,sg=0: 871609 GWT:TPS:TOPIC=mygateway1-out/2/3/2/0/0,MSG SENT 871670 GWT:TPS:TOPIC=mygateway1-out/0/4/1/0/47,MSG SENT 871687 GWT:TPS:TOPIC=mygateway1-out/0/3/1/0/0,MSG SENT

It's a air cleaner. I want to put a timer inside. The timer has four choices:1,2,3,4 hours to choose from. The problem I face is that I can't use IR remote to start the timer. Thanks for asking.

@mfalkvidd I took a glance at the embeddedadventures code on Github. They have a separate sketch for the samd21. Since I'm using a FeatherM0 could that be the reason why? I don't have the skills to decipher the differences. Once again I appreciate it! I added the serial print to the beginning of loop(). 15:37:58.624 -> At start of loop 15:37:58.624 -> At start of loop 15:37:58.624 -> At start of loop 15:37:58.624 -> At start of loop 15:37:58.624 -> At start of loop

@woeka Yeah you are right, i should change the code to 2 DS18B20's with eachone its own ID, thanks for the advise, also thanks for sharing your sketch.

I made some tries with 115200 and 38400 too... Results are the same! and using MySensors library 2.2.0, too! and using OpenHab too! While not connected to controllers... no NACK messages, every send messages got OK... and sensors don't lose gw connection (no continuos FPAR messages)... This is sensor log taken by Arduino IDE serial monitor (gw is connected to openhab): Two loop runs: in first loop one value reached gw (temperature one), 2nd and 3rd value had NACK. in 2nd loop no value reached gw (all have NACK). This behavior is quite usual, and it happens as soon as booted and while running for time.. Even initial presentation gets "NACK"...

@kimot said in Help with Lua: ' Thanks but it didnt help

@nagelc This seems to me the proper way to do it. Presentation of data on web/app should not modify the actual data from the node itself. For now HA is a no go for me until I get a chance to look at the HA mysensors code to see what it is doing.

@mfalkvidd OK I'll try that. But as expected, there is no suitable capacitor left over in my box.

Hmmm.... today I managed to connect this node to gateway. I just rebooted gateway...

All solved with the correct modules. NRF24L01+ instead of NRF24L01

@mvader MySensors currently does not support queuing commands.

@coconuts looks like the IRrecv library is present both in your sketch folder and in the libraries folder? IRrecv Should probably only exist in the libraries folder.

Thanks to both of you. I did solder it back. I will replace them just to be sure.
