Thanks for the screen shots.

I have no idea what the source of the issues were. My settings were fine, but I would get a device is busy error when trying to pass it.

It doesn't really matter to me as I will be running it as a KVM based guest when it is actually in use. The Virtualbox/VMware setup was only for testing.

You might have memory issues. Too many proggys running at one time.

What host OS are you using? Mine's on Win7 64 bit.

Hi

Firstly thanks for all the brilliant work with this. I've been looking at BrewPi for a while and collecting the various components but had been hanging out on the shield as it's the most expensive part and I'd enjoy seeing how it all works by putting it together myself.

I'm not sure if this has already been answered as this thread is so long but I have already purchased 2 fotek SSRs and am not quite sure how to wire them up instead of the 2 channel relay board. I know people have questioned the reliability of these devices but I'd like to try them as I have them in hand.

Also I presume it's possible to se up the system with the basic configuration on page 1 of this thread then add the LCD and rotary encoder as per the instructions on page 118 at a later time?

Yeah you can hook up the ssr in the same way. But id recommend using at least a diode to prevent any voltage from leaking. I have had a number of foteks fail in me in some weird ways and I just don't trust them.

Sorry to sound stupid but what do I connect to each SSR?

I can see the relay has a 5v, ground and 2 connections from the arduino. I presume I need one connection of the arduino to each SSR then the 5v? What about the ground?

Your fridge/heater seem to be cycling on way too often and your beer/fridge temps look like their fluctuating a ton. Thats why the fridge temp is banging up and down because its trying to figure out what temp to set your fridge to to keep the beer line flat, and 35F and 70F are just its lower and upper limits. The limits are set by the PID maximum and its default is 18F(I think) so if your beer setting is 60F, the warmest your fridge will ever try to get is 78F, and the coldest is 42F.

Keeping the PID Maximum small(like 10F) is good for keeping the fridge from overshooting, but it also restricts you if your trying to cold crash. When i want to chill something really fast i set it to something like 30F so when i set my beer to to stay at 33F it can get the fridge way down to 0F to speed up the chilling.
Thanks - I hadn't yet got my thermo-well, but just did and got it installed.

Default Actuator not kicking on

All,

I installed everything per the guide and confirmed I am able to control the actuator by switching from inverted to not inverted on the PIN type.

However, when I do something as simple as set the fridge constant temp to 30 (currently at 55), nothing happens.

Thoughts?

Default HOWTO - Make a BrewPi Fermentation Controller For Cheap

The software won't let you go lower than 32f which is freezing. It's a safety measure to keep you from ruining your beer…
