Solved. Issue with power supply. Added a capacidade to power source.

You should only include the relevant header file in the file Gestion_Porte.hpp, not Mysensors.h For example #include <core/MyTransport.h>

@nekitoss I used 3.3V pro mini with regulator removed and powered by Vin pin. Also removed leds from the pro mini. I used minicore bootloader. I used the small pir sensors and again removed the regulator to power directly from the pro mini outputs. After that sleep the node and trigger on interrupt. Send battery level once a day. Use inbuilt battery level monitor and not external components that constantly drain power to get battery level. 1.8V is 0% on the graph (not visible yet!) but I have had nodes working below 1.7V It's a matter of luck with that it seems. Hope this helps you on the right track. I'll try and help if you want. [image: 1697446591518-1ed.jpg] This is the latest image and still going strong after 18 months. Voltage is at 2.903V Here is photo of the test example - I need to make a case and produce more of them over winter..... [image: 1697446939496-20231016_095845.jpg] Here is the same build/code of a window sensor. Similar time frame but hardly triggered..... [image: 1697447658685-2ed.jpg]

Hi all, Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May. Hope this helps.

I'm afraid, the MYSbootloader is only available for the AVRs.

I deployed 5 sensebender nodes just after release in 2015, all with 2 AA batteries from ikea.1 died within a couple of years, because it was placed outdoors. But the rest kept going, and all have been going until this year. So 8 years of battery time on one set of batteries.. I think that is excellent battery life.. ;)

Thanks for the quick response. Yep! When I updated the IDE I forgot to modify the settings (915 MHz) in the new myconfig.h file. Doh! All good now.

Of possible interest: Here's a guy who is building an inexpensive open source ethernet controller for stepper motors: https://www.youtube.com/watch?v=80j7L1H61Hw If you listen to the end, it's revealed that there is now generous funding available which allows people to do this kind of open-source development as a full time job, which is what he is now doing. For that reason, I think there's a good chance he will complete his project within the allowed 6 months., and so by the deadline it will likely be nicely polished.

@skywatch said in Awesome tip: run LinuxFX instead of Windows!: @NeverDie Thanks - Interestingly they show a free version on their site still. Did they revert due to bad publicity? https://www.linuxfx.org/ I stopped following it, but I seem to recollect that the free version was noticeably missing things--otherwise, who'd buy the paid-for version? Anyway, its standing on Distro-watch has fallen considerably. It may seem unfair to niche distros, but I think it's generally better to stick with the more popular distros, unless you have good reason to choose otherwise.

Some humidity sensors are known to lose accuracy with age. For instance, the Si7021 is known to have this problem. If that matters to you, then the best choice is to pick sensors that have datasheets and which have specs as to their expected longevity or accuracy over time. Then buy from mouser/digikey to be certain you're getting the real thing rather than factory rejects or counterfeits. For extra insurance, I avoid electrolytic capacitors entirely whenever possible. I buy only 7XR rated ceramic capacitors that are overspec'd. The difference in price is small compared to a failure down the road.

@Matt Yes, the landscape there is incredible. Unfortunately, I mostly have to work when I'm there :) Where are you from?

No. For RFM69 you need Sensbender bootloader and external flash. Then it works.

Its seems to be working with this last sketch https://github.com/paolo-rendano/MySensors/blob/c01e14d0942de68126d67325a0687b1a6ce4fa16/examples/WaterMeterPulseSensor/WaterMeterPulseSensor.ino need some time to test it thanks

@monte thanks, did it!

@Dan-Mincu Hello I am looking for help because I have the same problem. Can you show me the code you use to set power down radio?

Same issue here. HA receives data from Ethernet Gateway for only a few minutes and then: DEBUG (MainThread) [mysensors.gateway_tcp] Connection lost with <_SelectorSocketTransport closing fd=42 read=idle write=<idle, bufsize=0>> I also have MYSController connected to the GW and it remains connected. There is an open issue as others are also having the same problem. Am wondering if anyone here is having success with Ethernet Gateway connected to HA.

The output of the display could also be sent over serial, but the whole idea is you can walk around with the doctor and improve your results as you go.
