Awesome project!

Added an update.

@mfalkvidd do you know the answer to this?

Welcome @aliansari. I hope MySensors gives you as much you as it has given many others.

There are also a lot of circuits using 555 timers and some old CMOS or TTL chips that easily create the oscilation you need. It draws a bit more power when the piezo is active. But for me that's worth it, because it gets rid of the complication in the code.
And is you have a bad MySensors radio connection, MySensors will keep executing code that might interrupt code. Which is annoying for applications like this, because it will interfere with your piezo sound. That's why I prefer a hardware solution or an active piezo buzzer. The ones that have a range from 3.3V to 24V are usually very load at 24V. They can be driven with a simple fet.

At least that's how I look at electronics now, don't jump to a software solution when some old skool electronics make your life easier.

But I love the project!

So almost time to create a 3rd gateway? :) I'm switching over to RFM69 for now, due to it's high range. Although it's significantly slower than NRF. So Curious about the performance of CC1101 any stats on power consumption?

I have no experience with inclusion mode as Domoticz doesn't support it (I believe). What happens if you just use a cat < gateway_dev? Does the gateway respond to nodes?

For me personal, because MySensors has much more capabilities that most haven't used yet. So to me, I haven't found an alternative that comes close to MySensors.

The only thing is. For the easy stuff you don't have to program at all when using esp with HA. But that goes over Wifi and to me that is a No-no.

Not sure why but when I checked it it had limitations. And I don't want my sensors and such running over a Wifi network.

@monte thank you for that one. Although almost 2.5 times the price it's cheaper than other European options.

@nschurando I don't understand why they do it for inexpensive parts as well. Allthough they said it was a measurements against shops like Aliexpress that are too competive for the EU shops.

It won't help as Aliexpress will find a way to bypass the rules. They will built some centers in Europe.

For shops like PCBWays and JLPCB I don't see that happen. So it's sad for us makers.

Merry Christmas all!

Not sure if you need to erase the eeprom from the node. As the key is stored within the encryption chip when you sign it - this is somewhat of a guess, based upon my understanding of signing.
Erasing the GW eeprom wouldn't be a bad idea. Because that's where the administration probably is stored. As far as I know other nodes are not influenced event when they are repeaters. As repeaters don't even know wetter the other nodes are signed.

Hope my 50 cents help out.

Probably best to post the debug and put the out come through the log parser. I myself have no experience with signing. Not sure but I believe I vaguely remember the gateway needs to be signed as well.

I actually write a non MS sketch first - well for the more complicated things - and when that works I add MS code. That way you can be sure that everything works fine before you enable MS on your node.

@Arvie_Mamayson It was fixed a couple of weeks ago. I just tested and works for me

You'd have to implement the serial protocol. But in all honesty why would you put in all that effort while Domoticz and Home Assistent already do it and support many more type of different protocols?

@ben999 Yes I have 3 gateways 1 nfrf and 1 rm for production. And 1 nrf gw for test. The test gw is on a separare PI

I might run a 4th gw. Also an rfm on the test machine.

@ben999 Thank you for the offer, but honestly I have been hand soldering SMD for the last few days true a magnifying glass. And I cursed a lot lol.

I will have two networks. NRF for inside the house and RFM for the outside.

I'm curious however how it will work out. So keeping an eye on this log.

What is the mount size of those capacitors. 0805 with a magnifying glass is kinda doable. But I don't think I can do smaller without having to buy a digital microscope

PJON is really Cool. But not always very practical. But the whole eco system is well thought off. I was much impressed when I read about it.
