A better day today. After switching my WIFI to a separate access point, up to now the WIFI is holding – I’m not convinced but for now all seems well. That has allowed me to spend a little more time with Blynk – and after chatting to the Node-Red node designer – and getting an update out of that, I now have Blynk server running on my Raspberry Pi2 – so between that and the Node-Red App I can now control stuff with a decent App – still some way to go with this but it’s starting to look useful.

As you can see in the picture – I have 4 RGB controls (suitably slowed down thank to the excellent Node-Red delay function), temperature and humidity monitoring and a couple of on-off buttons with feedback via LED. All working a treat.

Below you see the Node-Red code driving this – all very simple – the delay function is used to limit the rate of change for RGB and PWM as the App has a tendency to push stuff out very quickly.

Other than that it is all very simple – and when the designers get around to allowing more than one page per project, it’s going to get one hell of a lot more complicated

And with that – an early night I think.
