@MrRobots that was exactly my first problem, and never find the cause. Just switched to an esp gateway with a good power source.

Then the second issue seems like the gw "banning" the network or a part of it after receiving something it wasn't prepared to. Just my speculation.
Does that last one seems like anything you have?

I recommend that you build a WiFi or Ethernet gateway and you will discard several causes in one shot. I had the same problems with the RPI gw and that helped a lot.
Could be problems with the gw service, wiring, but also the RPI2 power limit reached on the USB lane, the power supply not being enough specially if you added WiFi to the RPI, or the system being resource hungry at some moment.

Also for diagnosing I would stop some nodes and try. After solving the first point I had this problem. It happen to be a far node sending something weird to the gw due to the long distance.
You can stop the farther nodes or the ones of one kind. You could end with a working system excluding only one node, like in my case.

@alexsh1 Truly, but that's what it's meant to be.

@gohan +1 to that.

My father was electrician and tought me something. I'm programmer and I also do lots of database and network design and management... And I can assure you that combining skills needed for today's ha development is not trivial.

It's because microcontrollers language and flashing methods. If powerful and efficient ones that could run any Java or lua like language, loaded through simple Bluetooth were developed, the situation would radically change.

@gohan Yeah, but what is not that intiutive for me is why when load increases in the mosfets side, the ams regulator goes away.

Anyways, no one knows what max led strip length is this board good for?

@gohan As you suspected, it was 12v.

Mmmmm... How much have you pushed this board? I mean, in terms of load.
I just had one fail at me and I'm trying to understand what component may have been the weak link.

It was driving a 5m white stripe when it turned himself off and on again, but although the light was still on the node was down. I took it out and almost burned my hand. Not the mosfets, but the arduino and radio. Nothing seems bad (components good looking, arduino seems to start) but as soon as you apply 12v, even without load it starts the barbecue.

It seems that the mosfets are good to 4,2Ah if I understand it. So what would be the boards specs?

@mfalkvidd Look in the ide for language inspection errors.
Sometimes while crawling the sources vs decides you have some invalid code files or dependencies, then it changes the file types to avoid live dependency resolution loop.
Then you loose auto completion, error detection, navigation, etc.
Specially if you use resharper plug-in.

Libraries like mysensors confuses the ide.

@gohan +1 on vs+vsmicro.
I'm a be developer from is first version and I could only seriously start programming in Arduino when I found the plug-in.

Last week, also stumped into other free ide that reuses the vs distributable, while trying to get mysbootloader to compile. It seems a nice stand alone solution. I can't remember is name but I think visual micro comes from it.

@rejoe2 No, I didn't see this. Been out more than a year by an accident and I'm still getting used to all the changes.
Thanks!
