Not sure if you can see what you need to see there, not home now but can take more photos later or explain if needed.
Basically just take your control output to the first ssr then loop over from this to the second. If using additional switches, place them in the output from ssr. Would advise using double pole switches

That's very neat. What model SSR's are they? Not seen that style before.

They're crydom. Got them from rs components. Not cheap but really good quality

Could the Smartpid be made to work with a "Tilt"?

Yes, But ;)

the tilt is a lightblue bean based solution which uses b/tooth ble to pass messages to a smart phone. while the smartpid is wifi enabled, so a direct link isnt straight forward, but you can use both to sync with an online server iot or mqtp..

However there are now a few esp8266+accelerometer tilt versions with full wifi capacity

It arrived today , thanks for the speedy dispatch Davide . Just waiting on heatsinks and ssr's to land and find a suitable box ill attempt to knock something up , ive no idea what im doing tho , your box looks well complicated :shock:

It doesn't need to be that complicated. Just lots of wires in mine as I used switches for elements and pump and because I use 3 separate 13a supplies for the 3 heating elements in my setup

Sorry for delay in answering…very busy with the live streaming session yesterday (nice experience indeed..)

I see some doubts about connections and usage of the smart box…I try to give you some hints, some other materials on both manuals (user and install&config)

The key word I would like to transfer is : FLEXIBILITY

In the brewing application you can manage two independent process/channels : the mash process (with all automation steps) and the HLT process (simple PID temperature control)
On top of this you can manage the pump/stirrer

This from LOGICAL point of view…the nice things is that you can assign PHYSICAL resources to each channel/process so basically have total flexibility in your setup and wiring

Some example
The elecric mash heater can be controlled by
-SSR on the SSR port
-SSR on DC1 or DC2 port
-Direct control with mechanical relay (up to 10A)

If you have a gas valve you can connect
-direct to DC1 if is 12V valve
-Via mechanical relay if is 220V

The pump as well
-direct drive 12V 1A (solar project, topsflow)
-mechanical relay if is 220V (march pump..)

Below some schema…just few example

Single vessel BIAB . electric heating and 220v pump

Image

Dual vessel (MASH+HLT) all electric +220V pump

Image

Dual vessels , gas heating for mash , electric heating for HLT

Image

Endless possibility !

Hope you like it 

Nothing is complicated with smartPID ...


Have a look to above schema…just wiring in the proper way leveraging the flexibility of configuration
Read also the manuals…
And if you have any concern post your setup (gas/electric..220v/12v…single/dual vessel) and I draw a schema for you !

I have already answered this question somewhere…
Apart form technicalities on how to make smartpid talk to tiltometer ….what is the concept behind ?

What is the service logic? The workflow? How could tiltometer influence the smarPID process ???

This gives me the opportunity to announce you that I have put in roadmap for the smart thermostat the profile management: possibility to define ramp/soak etc..for the fermentation control !

One quick question, my HLT has 2 elements in it. In order to control both elements at the same time, is it ok to split the SSR 12v switching feed and connect up 2 seperate SSR's (one for each element)?
You can manage 2 heating elements with both options
1) put in series or parallel the heaters and drive via HLT channel + 1 SSR , assuming SSR has enough “power”
2) use two SSRs and drive in parallel with SSR (or DC1/DC2) output
what you can’t do is to have different logic/behaviour of the two heating element on the same channel (ie MASH OR HLT)

im sorry if this is a stipid question , but i cant make out via the diagrams. I ran 2 elements off one plug and an stc before until it melted my plug and socket , how can i run 2 elements the same time with this?

What wattage are the elements?
I use 2 X 2.4 kW but have to use one supply for each.
Max for a 13a supply is about 3kw

i had suspected you used more than one feed , but it doesnt show in the arzaman's graphics wiring diagrams. The elements im using now are 3kw led ones

Then you either need a supply for each if using 13a (still pushing it if you ask me) or a dedicated circuit for your brewing, probably 32a
