RE: Relay Node with Fallback feature, if network is lost or controller is failing...
Depending what's connected to a relay, I wouldn't make it go on or off depending on the controller state. It can lead to dangerous behaviour and it's prohibited by law in my country.
In all honesty I have my Sensors running for a long long time. It's stable and more reliable than anything else I have running in my home.
But like @eiten says yo could write a sketch that queries for a variable. But I think I'd go for a controller side solution. That would "ping" my node and send a nottfication to my phone whenever the node can't be reached.

RE: Relay Node with Fallback feature, if network is lost or controller is failing...
To my knowledge MySensors is a stateless connection, so you can not know when the connection is lost after the node has been initialized. Also when a node is connected to a repeater node, I was told you will get an ack from the repeater even if it fails to deliver the message.
I'm more curious to what you want to achieve, or what you've hooked up to that relay?

RE: What did you build today (Pictures) ?
@monte I had a gut feeling about it, since dimmable led bulbs like trailing edge. I'll keep looking for a good 220v led bulb dimmer schematic.

RE: What did you build today (Pictures) ?
As much as I love the 328 I think I should make the change to a different board for me they fit my needs as I try to keep the logic in my nodes as small as possible. I have one rule though: Manual first, for actuators my nodes need to support manual control.
Thanx for the schematics, I'll have a look at. Can you control led light bulbs with this schematics?

RE: What did you build today (Pictures) ?
@monte do you have a schematis for that dimmer? If so I'm interested in it

RE: Powering ESP8266 / NRF24L01 repeater through USB (improvement)
@Kokosnoot good solution. I remember the discussion in the early days of MySensors. I've powered the radio's for most of my sensors from the 3.3v regulator on the arduino board and for me that works perfect. But for my latest designs I decided to add a separate ams regulator for my radio's like the guys suggested in the beginning. Because you basically want the on board regulator to power the mcu only.

RE: Wall mounted 'mood light' v2
@adds666 I'm not sure but I believe Domoticz prresents it's dimmer values in steps from 5 to 100 I believe. It'd about 10 steps. That's why I'm not sure if you can add more patterns. Unless you indeed change it to a percentage. Hope it helps

RE: Balcony flower box irrigation
@pbw a gateway's function is to act as a gateway between the nodes and a controller. I don't think you will have all of the needed memory available to add logic to the gateway and you will make your solution very static.
You can implemented your own lightway controller, just have a look at the Serial API. But controllers like Domoticz are lightweight and the already over a browser based interface. And most of them are easy to setup creating a much more versatile and dynamic solution.

RE: MySensors Serial Gateway with USB 2.0
@DeepCore That is a need looking design. Did you consider using an alternative power supply other than usb? My Pi can't handle a lot of usb devices power wise, so I'm using a powered usb hub. But the wife doesn't like it, it's messy xd
