@KevinT yes in general subghz radios have better range than 2.4ghz. I might have farther nodes but for example, I have one rfm69cw at 55m from the GW and it's ok, with many obstacles on the path (7x rock walls, a part of the roof is metallic, metallic doors etc). This depends on many factors of course

The distance sensor is supported in the beta version of Domoticz

@gohan Yes, you are right, this is done by cnc router.

The send-function is used to send updates to the controller, in your case the physical-button-switch-change. Doing the send, does not control anything on the node itself.

Hi all, Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May. Hope this helps.

@Alphalove I highly recommend itead products, especially for those just getting into MySensors. They remove alot of the pitfalls that electronic noobs (such as myself) encounter when building their first sensor nodes. I used the RMini to build my first relay and it could not have been easier. Many of the troubleshooting problems posted on the forum have to do with setting up relays and these boards eliminate many of those issues. I also recommend the nano shield from itead to any entry level electronics noobs for setting up early sensor nodes who are not ready for intricate soldering. It provides a nRf socket and a power jack and breaks out all of the nano pins with individual power and ground headers. Just plug in a nano and nRf and program from USB and power the entire setup through a single jack - perfect for beginners.

@C.r.a.z.y. yeah.... those are VERY bouncy. are you interrupt triggering or just using a state change? post your code, let's make sure you have it de-bounced enough.
