thanks bud - yeah for less than 6k with everything I do think it has saved a hell of a lot of money. From what other people have said nearer 30k for my spec pre built!!!It really is looking good. And will represent a MASSIVE saving on a factory built unit. Especially given the spec you have built it to, as the shed manufacturers really start adding in cost when you start insulating them properly
Hi Neil,why are you using that system? Is it cost? I'd have thought its a lot of effort to do when there are a huge number of off the shelf solutions now?
I designed it all Neil from component parts - there is basically an arduino mega with a a piggyback w5100 network card, 2 8 ch relay cards for the lighting(and spare channels on them) and a 4ch Solid state relay card to control the heating. In each of the rooms is a DHT22 temp/humidity monitor and one also outside. I wrote all the software myself. The blynk app is free and just adds control vai IoT(internet of things). All the lights can be worked with physical switches in the each room and these feedback to the arduino to update the app in Blynk with the status of each switch. This keeps them in sync with the appKev,
looks like a cool system, where did you get the controller from?
[QUOTE="Big Phil, post: 230598, member: 194"
Did you not put a draw cable in the conduit?
no guys the PoE is just for the IP camera on the front of the shed there are 4 no PoE on the switch that I am using for the arduino etc The arduino has its own power supply you can just see it in the top right of the the picture earlierAssuming you are using the Poe to power the ardunio ?
Can you run it temporarily of an injector or dedicated PSU for a bit to eliminate Poe issues ?
Thanks Paul - think I have it sorted now just debugging software and trying find the other ends of cables the appear to marked up wrong for the wall switches - aaargh!!!My guess would be the arduino is dropping connection if its not used for a while? Might be worth trying adding a periodic ping request in the main loop every 5 mins or so?
