@tsunami My setup is max 50m radius and 433MHz standard power RFM69s so a small 1/4 wave whip works reliably even from a below ground pump chamber 10m away. Your 915MHz at 200m SHOULD work on 1/4 wave if obstacle free line of sight, but you could try a 2.4GHz Wifi router at one location and use a mobile at the other to test if you can see the router. I can see at least 3 neighbouring routers identified on my mobile from over 40m away through masonry, 10 on the laptop, so it's a simple enough test. If you can see the router on either, 915MHz should be rock solid with a simple whip and no need of directional antenna.

In the default wiring, D1 is the only unused pin that is easy to work with. D2 is used for CE so using it to blink a led as well will not work.

@skywatch @mfalkvidd Thank you for your comments. I am using Moteino R4 and RFM69 connected to hardware SPI pins. I tried the same pin with softSPI, but I could not get success. Now I have altered the ADE7763 Arduino library to update SPI settings on every call. And added code to update the only flag on ADE7763 interrupt(like we have in RFM69_new library). Seems all look somewhat ok. I think for RFM69 we use a default clock speed. for ADE7763: SPI_CLOCK_DIV4 Are you using pull up resistors on the CS lines to each device - that might be worth a try too.... Yes, I have

has this ever be tested ? Just ordered some boards and noticed that VCC of the PCB is wired to DIO5 instead of 3.3V of the RFM69HW module.

Thanks for your quick reply! The solution was indeed to put the ./configure parameters on the same line; I also changed to a serial gateway which is now correctly recognized in Domoticz. I did not need to change any pin definitions (yet). Yeah, the two capacitors clearly shown are indeed not very effective for the radio module, there is however another capacitor directly soldered to the radio, which is a bit hidden in the picture. Thanks again for your help!

@kalina, Thanks. So it will not work for my configuration. Wall switch (push button) is already installed. No possibilities to draw more electrical wires. Moreover, if i put the board near the light, i have just the Neutral and the return wire from the wall switch. No Live wire to power on the mysensors board. I think in my ase the best way is to manage everything in my garage in the electrical main board where all the wires are mapped. I can get L + N for mysensors power supply. And i can continue to reuse the original wall switch independently of the Mysensors board.

There are also other solutions that have I2C bus pins on the shield and if you are going to make a battery powered node, I'd suggest to use an I2C sensor as it will be much more battery friendly

I'm very interested by your setup. It has been a shame to have some low voltage power in order to measure power consumption I hope you can display something soon. Regards, Qq.

I had the same issue today with a RFM69HW connected to a Wemos D1 Mini. The above solution worked, thank you so much. I had no idea what was going on. I also have a RFM69W connected to a generic ESP12-E and with the same code I didn't need to reset. Seems to be hardware related.

@mfalkvidd oké, clear! Unfortunate. Guess a couple esp8266 couldn't hurt.

@gohan said in Arduino Pro Mini Shield for RFM69(H)W: If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it. thank you just what i thought . about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board. sorry about hijack this topic, i though i was on general discussion
