Here's the one you want: http://www.legrand.us/passandseymour/switches/manual-controllers/1276.aspx

Generally yes, but that is a momentary contact, double throw switch. Try a continuous contact (standard), single throw switch.

What happens if you disconnect the Pi from the Sainsmart and provide 5V power to only the relay board? Are your outlets on or off then when wired to NC? What about NO in that same scenario?

It looks like you wired the outlet relays to be normally closed (NC). Any particular reason you did that? It is probably the cause of your power up issue. Have you tried moving the wires for the outlets to the normally open (NO) terminals? Why are you triggering the SSRs with relays...

Presuming we are discussing CBP, no need to modify or add code for the PiFace. For 1-wire support when using a PiFace, however, you will need to get to one of the 3.3V pins (1 or 17) for power, pin 7 for GPIO4 data (or use a script to choose another GPIO for 1-wire), and one of the many ground...

The RasPi will pass 5V to the PiFace using pins 2 & 4 of the Pi's GPIO header. All you need to do to bring 5V to the Output terminal on the PiFace is to shunt the jumper at JP3 (lower right corner) on the PiFace, connect the PiFace to the RasPi and power the RasPi through its MicroUSB connector...

You don't need SSR's for the pumps, at least not for up to 2 pumps if you use a PiFace Digital. The purple wire to the kettle SSR in this PJ diagram posted above would connect to the 5V output (orange) terminal of the PiFace. The yellow wire to the SSR would connect to any of the eight...

Anne at Inkbird wrote me on October 16th to say it will be back in stock "... after one month." Given that they have launched several new products over the past month, I wouldn't be surprised if it takes a bit longer than that.

The other option for burner control would be customized Python code that handles the solenoid lockout logic based on input from a 1-wire temp sensor. See the CBP Github pages (Branch: Dev2.2) for very basic guidance on how to add a custom logic. You might also want to ask on the CBP Facebook...

The boards are essentially agnostic in that regard; the outputs can be used for a multitude of purposes that can accept 12v input, except of course for the 1-wire inputs. From what I can tell having run the software only in demo mode so far, is that you could use it to control a burner with a...

What I like about Kegconnection is that they allow you to customize your order when purchasing a draft tower. For example I want to replace the single tap 2.5" tower which came with my kegerator with a triple tap 3" tower, but I only need to purchase one new faucet at a great price...

Yes, however, Gembird is probably best used for fermentation control. Mash control is better done with the higher switching rate of a SSR, where you can vary the power more than just on/off. I believe CBP currently supports only the Dallas one-wire protocol for temp sensor input. The...

Presuming the GFCI is upstream of anything else in the panel and the panel is wall mounted away from any water source, i.e. where you mount a spa panel, I don't see why not.

I'm good with 26-pin and may grab a 40-pin as well. Have you finalized a BOM?

First off, are you sure your TFT is 800x400 and not 800x480? Secondly, is it connected through the HDMI port & USB or does it use a serial interface? Finally, have you edited /boot/config.txt? If it is a serial TFT you'll need to set HDMI_FORCE_HOTPLUG=1. If the resolution is really 800x400...

In.

Don't connect an SSR directly to a RasPi GPIO pin. You want to buffer the GPIO. The max current the Pi can handle on one pin is 16ma and the max total for all pins combined is 50ma. Depending on your SSR you are likely to exceed the capability of the Pi. Auber specs the Mager SSR they sell...

Thanks!

@SHvanBommel: What is the pitch of the various terminal connector pads on your board? It looks like the 1-wire pads are 5.08mm (twice the pitch of the pi header) and the 12V GPIO pads are 3.5mm. Is that correct?

In case that wasn't clear, click on the word 'UNIT'; it is a link to the panel where you can select which option, C or F. The link is not underlined until you click on it.
