Hardware

@Chester one is enough. They are connected to each other on the pcb. You can verify this by putting a multimeter in continuity mode or resistance mode and measure the resistance between the two ground pads. The resistance should be zero.

@micah I have had this happen to a couple of mine too. It only takes a few times before I learned never to apply 12v to the raw pin :grimacing: I have been able to revive all of my pro minis by soldering on a new capacitor here: [image: 1478302518407-upload-0e34ea93-e569-4bda-a128-01f155ebb85e]

great news :) with the new nrf modules there is no more range problem :) for the gatewane i use nrf24l01+pa+lna and for the sensor node nrf24l01+. now from every place in my small flat the connection is perfect :)

ok. Thanks. then i will keep it with the nrf24.

@mfalkvidd said: e Thanks v:) the instructions were great, now lets see if the child or the dog gets the first try :)

@mfalkvidd Tnaks, I saw that Adafruit had a library and code or this that should be ESP8266 certified ... I'll try. Thanks for quick support

Anyone? Any clues?

@t1m0 I suggest you post it in Troubleshooting. Let me ask you if I understand your question correctly - your PIR is triggered randomly?

@Alexandre-Magno Hi! Look here: https://www.arduino.cc/en/Main/ArduinoBoardProMini Check the documentation/schematics section.

Hi, on gateway I'm using a NRF24L01+PA+LNA and everything works fine if I use NRF24L01+ or SI24R1 on sensor side. If I replace NRF24L01+PA+LNA with something different (NRF24L01+ or SI24R1 module) the communication does not work...

I built a dimmer for my sons bedside lamp -> https://forum.mysensors.org/topic/4808/dimmable-led-actuator/15

@alexsh1 Hi Alex, I tested the Sanity check on the the Arduino sensor node, and status came back OK. However I could get this to work on the Raspberry Pi, seems like this function is not yet supported. At least I couldn't find any info on it using the "./configuration -h". I don't have a AMS1117 available so I can test that. I connected my Arduino Nano and NRF24L01+ to the Raspberry Pi via USB, that would really well. So I might just use this solution instead as I see little benefit of connecting the NRF24L01 directly to the GPIO pins on the Raspberry Pi. Next step is to start building some battery powered sensors that I can use, and get MyController setup properly.

@AWI said: @LastSamurai I can find a lot of these even on main stream sites Thanks a lot! My bad, I did look for KaKu (and overlooked the NL part ;) ).

@parachutesj this is the way SSRs work. I do not think you can test them without a load

Hi all, Thanks for the replies. Turns out my D1 was faulty, or becoming faulty. When I double-checked on the USB supply, it didn't work there either. Are they particularly static-sensitive? The output of the converter goes to the 5V & GND pins on the D1, and also to the 5V and GND connectors on the LEDs. I use pin D2 of the Wemos to send data to the LEDs, via a 470 ohm resistor. I specifically wanted to add the 12V to 5V converter because I plan to run these lights at the end of long wires (Xmas decorations), and was worried about voltage drop across the wires. Maybe it's a bit of overkill... when I checked, the lights work OK on 3.6V Cheers, Frank

@clio75 Just a warning. Just ignore it and be happy. ;)

@AWI said: e 5 volt is the refer Once again. Big thank you @AWI . As you understand I'm new to this battery thing and it's kind of driving me crazy :)
