    @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...

    @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.

    @parachutesj this is the way SSRs work. I do not think you can test them without a load
  • 12V supply for Wemos D1 mini & 2812 LEDs

    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

    I use Abloy EL582 and with that you can either set it to be open as long as 12V is applied, or closed as long as 12V is applied. Simple as that. I control my doors with a KNX switch. If you go with a lock like this and have the door closed when no power is applied be ware that you need a key to open in from inside in case of fire.

    @Vasil-Vasilev yes, you need to select which frequency (433 or 868 MHz) when you buy the radio module.

    Have you seen the thread on here about fake HLK modules? It could be that you had a batch of the dodgy ones.

    @hek Thanks hek, it was indeed the problem.

    @Patrik-Söderström - I made some more tests but with the same conclusion... still lurking in the back of my head what to do but no good answer so far. I dont want to use RpI even if its a good sollution. Its way to expensive compared to my normal projects. Maybe install a real waterflow meter somewhere... not that expensive in that link AWI posted... dont know if it can handle a normal household flow though.

    @GertSanders Hi. I'm not in front of my eagle stuff but you can extract it from this: https://learn.adafruit.com/adafruit-rfm69hcw-and-rfm96-rfm95-rfm98-lora-packet-padio-breakouts/downloads Side note: RFM95W and RFM69HCW shares the same footprint whereas RFM69HW has a different pinout. So for my long range nodes, i prefer RFM95W/69HCW footprint, more versatile imho :) As tbowmo said LORA is a spec. On my side i plan to use RFM95W for its features and longer range, in raw radio mode as we're using with mysensors. So it could offer more flexibility maybe, if i need repeaters etc.. I started something (a lib) a while ago but not finished, and now i'm trying to refactor rfm69 lib, then rfm95 if not already done. If you don't find your wish in the link above, i can send you/help you with some stuff i have done. I hope this helps, a bit :)
