MySensors on Apple AirTags?

Apparently, they are based on nrf52, and can be flashed.

So we could run MySensors on them otoh, there are cheaper ways to get nrf52 devices.

That's a great idea.

I would really like to get OTA working here as it's freezing outside and I have to go there to update the software in the greenhouse control system. So please, can we have a 'how to' step-by-step guide to OTA? Please? S.

https://github.com/sandeepmistry/arduino-nRF5 Install this and find libraries for whatever sensors you have on that board. @basaksts said in nRF5 Multi Sensor Board (12-14€): Also I need an bootloader No, you really don't. You need ST-Link, or J-Link SWD programmer/debugger. Connect it to SWDIO, SWCLK, 3.3V and GND and program it using Arduino IDE.

I am new in this forum and I have a question regarding mysensors and iobroker. I did not work with mysensors up to now. Since some weeks I use iobroker installed on a raspberrypi. Now I want to integrate my 433 Mhz doorbell in iobroker. I know, that there is an adapter for mysensors in iobroker. My question is: Is it possible to get a notification in iobroker if someone is pressing the button on my doorbell? As I understood, I have to connect the receiver to an arduino nano and connect the arduino to my rasberrypi on which iobroker is running.

It's an awfully convoluted way of doing things but suspect your error lies in misunderstanding calculations mixing ints and floats and something screwy with your resistor bridge - It is always worth checking the bridge with a multimeter and raw voltage to verify the expectation. If you have 3v at the top of your voltage divider, you should be getting 0.9593v applied on the ADC pin which will be read as 892 against the 1.1v internal reference. The easiest way I found was to define a multiplier needed to derive the raw voltage, in this case (((R1+R2)x1.1)/R2) - For your resistor arrangement the max you can read is 3.4404v before exceeding the 1.1v internal reference. To reverse the ADC reading of 892 to raw voltage is (892x3.4404)/1023 = 2.9984 v. Perhaps this is a simpler way to do it float MULTIPLIER= (((1000+470)*1.1)/470);//Resistor bridge values in k and Vref int sensorValue = analogRead(BATTERY_SENSE_PIN); float batteryV = (sensorValue * MULTIPLIER)/1023.0; //Note the trailing decimal point on the 1023 for calculations involving floats

I had the same problem with "Emakefun LGT-RF-Nano für Arduino Nano V 3,0 RF-NANO LGT8F328P Integrieren NRF24l01 + Micro USB Nano Bord mit Antenne Interface" Using the default Compiler the Serial Messages were not working properly. I used this https://github.com/nulllaborg/arduino_nulllab Board Package and it worked(at least the serial issue). The rest I still need to test. I hope this helps some hours of trouble.

@isded from what is explained in this page it seems it is based on the Semtech SX1278 : https://www.makerfabs.com/sx1278-lora-module-433m-10km-ra-02.html
