Hi everyone!
I would like to share with you all something that I have been working on for some time. It isn't my first project, but it is the first that I have shared in this way, and I must say that I am a little excited haha
BACKGROUND
A couple years ago I was at my local electronics store and they had a sale on some wall switches which were controllable using rf433. Each box had two switches as well as a hub that converted an infrared signal into rf433 which the individual switches were able to learn so they could be turned on and off. At that time I was playing around with Mysensors but had only made a couple relays, temp nodes and the like. I bought these at the time with the intention of using my Harmony Remote Hub to operate the switches. 3 years ago will finally moved into our new home, and while doing so we somehow misplaced the whole Harmony setup, so up until a couple months ago these switches gathered dust in the garage.
Fast forward to a couple months ago, and with the help of some awesome members here, I was able to build a Mysensors RF433 Hub wot control all 6 of my switches. I had used a little maths to work out the signals, and even though I had only had 3 of the switches enter use, they seemed to be working as they should; that was until a couple days ago when I noticed that my pool pump which was powered through one of my switches was turning on every day at 1pm, despite no scenes in my controller (Vera 3) doing so. Long story short (haha) I worked out that when my fish tank lights turned on at 1pm, that switches frequency must have been too similar to the pool pump!
So the last couple days I have been doing lots of searching, and hopefully a little learning. I was going to use the Candle Signal Hub, but ended up doing something on my own. I was lucky and found someone else on the internet who also had 6 plugs and had shared the code for each switch, which was very helpful!
It's probably time for me to stop rambling lol so first here are some pics:
The Switch
The Hub
Please excuse all the extra wires on the Nano; it stopped being recognised by all my computers so I had to program it using an FTDI adaptor.
Here is the sketch. I am certain that it could be tidied up a lot.

I would like to give my sincere thanks to everyone here. I may not post all that much, but I enjoy reading what others are doing and trying to learn from it, although much of it is still way over my head! To @hek I still remember how excited I was when I found MySensors all those years ago, and I thank you and your crew for keeping this great community going!
I am also certain that most of you won't get very much from this technical-wise; I just needed to share this for myself. Thank you all.
