Hi,

I am trying to build a battery driven door sensor using EasyPCB and a RFM69 radio.

The linked documentation says you should use a DC/DC step up booster, but here says the booster creates a lot of noise that disturbs the radio.

Do the newer EasyPCB revisions take this into account but the documentation has not been updated? Or should I attach a step up booster (those, maybe?) and hope for the best?

Thanks!

Hi,

I hope it's ok to open these types of posts here.

I would like to use openHab on an Raspberry Pie 4, I decided on a RFM69HCW (868MHz) transmitter because those seem to have a good range (Admittedly I don't need all that range because I life in a small flat, but it would be nice to be future-proof).

I figured I could build good and cheap (battery driven) sensors with some Arduino Pro Minis, EasyPCBs and other RFM69 transmitters.

Is this a good setup? Or should I change anything?

About attaching the RFM69HCW to the RPi4: This is probably the easiest way to attach the RFm69 to the Pie, right?

If I got the documentation here right then the mysensors library is all I need to run the RFM69 on the Pie, correct?

Thanks for the help!
