ebuild is sad to announce its closure - it has become too time and resource intensive to develop, manage and maintain.

However, ebuild will remain on-line in archive mode (ie no posting facilties) for several weeks so that users can use it as an information resource.

> What I use when I can't get hold of 1Wire 'stuff'

Just stick an ESP-01 in to do this if you can afford the £4. You can write a simple UDP interrogation to read the thermometers from the Pi. If you get stuck then ping me an email or we can swap contact details (one of the committers on the firmware is this guy called TerryE -- no coincidence).

Could I make a half decent solar monitor from it?

Nick, short Q. Long answer and not for here. Ping me a PM and we can hook up by email, Skype, whatever. I'd enjoy that :)

My RPi (that runs www.earth.org.uk, my mail, DNS and many other things) is off-grid with PV.

My Pi, which runs my monitoring system, is powered by the grid.
I think with all the sensors and add ons it uses about 4W, so 35 kWh.
That is split 17:7 between Standard Rate at 18p/kWh and Night Rate at 8p/kWh.
£4.4 plus £0.84
£5.24/year
Is it worth doing any different?

It depends how you measure "worth".

I am continuing to experiment chipping away with drawing less from the grid (eg supplying more microgenerated power locally) and it's eye-opening actually doing it for several years in a row, even in a tiny way, rather than just waving hands and speculating.

I wonder if choosing different food stuffs could save more, bit like changing your car (not that you have one).
Some foods take less imported energy to process and store. It would be an interesting bit of hand waving.

So I also attempt to save carbon in what I eat and stuff I buy, and how and where I travel.

Just for example, both my business partner and I could have gone to Shenzhen to get our plastics made, and one of had to realistically, but I did without and let him go much I would have enjoyed it.

You can't just do one thing such as switching to eco dishwasher tablets and think that all your eco sins are absolved! B^>

Equally many of the bits of home energy storage are easy, but some are expensive and/or take lots of space and/or continuing attention...

I have one of the original RPI's, I got most of the way through designing a hinge automation system amongst other bits but work got so busy it has slipped. Reading this is giving me a kick to get it going. Oh and I'm a complete first timer using any of this stuff and code!
