Sensors error

How would you call an error that occurs when the measure the same parameter at the same point by the same sensor type but get slightly different results and it is not noise, but maybe manufacturing defect or calibration, we don't know. Inherent sensor error?

@bjacobse Excellent! You're the first and only person I've ever met who knows anything about this very important topic. By "hydrofob", I assume you mean hydrophobic coating? If so, just how effective are they at preventing moisture intrusion, and which type or brand of hydrophobic coating is the best?

1.8.12 is OK, so no more problems for you either I hope.

@NeverDie Nah, I'm fine. It's always helpful to get opinions and views from others, especially if they are more experienced in the matter, if only to set one's own viewpoint straight. I'm grateful for all you guys replies, but I don't feel like bothering Microchip with this. Regarding Nordic - besides the circulating copies / clones (like the SI24R1), I guess it's also not helping that they are fabless, unlike Atmel / Microchip, in which case it seems totally reasonable that the various fabs may have slight marking variations. I just didn't expect that from those ATmegas which seem to have been produced in one and the same factory. But it's certainly a neat touch from Nordic to offer a free test.

PS: one downside will probably be not being able to wake up programmatically and double the node as a e.g. temperature / climate sensor, as I had in mind. Sorry for the confusion above, too little sleep in the last days (at least I hope that explains it ) Perhaps @Yveaux can help here on how to combine pin change interrupts and timer wake into a successful sleep() command? So far it looks like that would be possible with Low-Power lib, but this is not compiling in conjunction with MySensors 2.3.2.

@Sebex said in Next generation dust sensor for MySensors: @NeverDie could you share your Honeywell code, I have trouble getting it to work. An example will help me a lot t learn from! I made a library for that, I'm updating it to autodetect some various PM, CO2, Formaldehyde UART sensors but I'll find the old version for Honeywell only tomorrow if you want. If I forget, harass me by MP

@Boots33 Thanks a lot for the quick response. I now have my Nano running as a serial gateway and it is connected via a USB cable directly to my controller (Raspberry Pi 4 running Home Assistant / Hass.io). I added a local motion sensor to the Nano gateway HW and pasted the mysensors MotionSensor example code to the setup(), presentation() and loop() functions as well as to the definitions in the top of the GatewaySerial example code. I disabled the radio definitions as I currently have no radio capability in my gateway (not sure if this was necessary). In Home Assistant / Hass.io I updated the configuration.yaml with the following text (as described on the Home Assistant integration help): mysensors: gateways: - device: '/dev/ttyUSB0' And it works In Home Assistant Developer Tools under States I can now see my motion sensor go on and off by the flick of my hand. I had expected a bit more bumps on the road just to get this far, but wow - I am obviously walking in the foot prints of people who have worked hard to make it easy for the rest of us. I am sure I will hit bumps on the way when the radios have to send results to the gateway (thick concrete walls with lots of steel), but for now I will enjoy this big success. Thanks again Boots33

I got tired of twisting DuPont cabels to get from different programmers to different boards. This is an adapter that lets me connect the programmers I commonly use (Jlink-mini, BMP, STLink clone) with the boards I commonly program with straight through wires. I left a couple unpopulated for future in and out.
