We are due for some cold weather this week, so I wanted to see how the setup will work. I still have to add the sensors but wanted to test out the main boards. I also worked on the relay outlets, I did not want to take the end plugs off so I switched to outlet plugs. Currently working on the sensor hut.
  
Howard, how do you remote update the sketch to your OCS system?

Thanks Nino

In the usual way.  A PC attached to the Mega2560 USB connection.

There are TFTP bootloaders for the Mega2560.  I guess one could use that across IP (VPN, etc.) to flash the Mega2560 but I haven't gone down that path.  Nothing to do with the OCS and nothing stopping you except for the hassle AFAIK.

This isn't the only one but perhaps the most up to date?

I was also looking at the WifIOTA and ArduinoOTA, it also mentions the ariadne-bootloader.  I will take a look at it, just wondering if that would be an option in the future.
Thanks

From what I understand I'd have to add a control to the website to reset the Mega2560 to place it in firmware upload mode.  I suspect that would be easy.
