It looks like the most common Arduino solution for temperatures above 125C is to use a K type thermocouple with glass insulated wires and a circuit that converts the thermocouple output to I2C. Will SmartPID support something like this to allow control in high temperature applications?

You are right for BBQ and high temperature you muste use a thermocouple with and amplifier
In order to connect to smartpid you need a conversion to 1-wire protocolo...
here is the solution

One of the key characteristic of SmartPID is the flexibility and versatility trough HW set up SmartPID can be adapted to mange different applications

below some example to illustrater the flexibilty


Single channel - PID (on/off) control mode - heating + pump

SmartPID reads temperature from 1 probe and drive the heating element in order to get the setup temeprature

Possible heating output configurations

SSR for electric heating [PID+PWM control algorithm]
220V AC relay for electric heating [ON/OFF algorithm]
Direct solenoid valve drive for GAS heating [ON/OFF algorithm]
Manually drive the PUMP (soft switch) with tow possible configurations

220V AC realy pump drive
12V DC direct pump drive


DUAL channel - PID (on/off) control mode - heating (gas or electric)

SmartPID reads temperature from 2 probe and drive 2 heating element idipendently in order to get 2 different set up temperature

Possible heating output configurations

1 x SSR for electric heating [PID+PWM control algorithm]
1 x 12V direct solenoid valve drive for GAS heating [ON/OFF algorithm]
Manually drive the PUMP (soft switch) with tow possible configurations

220V AC realy pump drive
12V DC direct pump drive


DUAL channel – ON/OFF control mode – thermostatic

SmartPID reads temperature from 1 probe and drive one heating element and one cooling element in order to keep temperature stable (fermentation chamber)

Possible heating output configurations

220V AC relay for electric heating [ON/OFF algoritm]
220V AC relay for electric heating [ON/OFF control algorithm]


so as you can see the possibility of configuration are really endless !

staty tuned

Happy to announce after 2 weeks from SmartPID launching that the second application on top of the SmartPID platform is nearly ready and is completely dedicated to home brewing process automation

What is new and different compared to the standard basic application (smart thermostat)?
Substantially Smart Home Brewing App adds to a standard temperature control features all the process automation and workflow to manage all typical steps for beer making. We have customized vertically the SW for the specific application leveraging all the basic features available on the platform
Each vertical application has off course it’s own set of data, process parameter and configuration and so is the smart home brewing app that execute all process steps according to in memory “recipe”and controls HW resources (heating elements, pump/stirrer, buzzer ) in automatic way

These are main characteristic of the smart HB application

• Single vessel (BIAB/RIMS) or two vessel (MASH + HLT) process management

• Electric heating (PID/PWM) or Gas Fired heating (ON/OFF)

• Recirculating pump or motorized mixer management

• NTC/DSB18B20 temperature probe

• Internal or external (in recirculating circuit) temp probe position

• Step Mash management (mash in/out and 6 step mash)

• Boil management with overboil and power control (electric only)

• Hop addition alarms

• Whirlpool management (hot or cold)

• Cooling management

• Full recipe management (new / edit /clone /delete)

• Mash profile

• Boil duration and hop addition time

• 10 possible recipe in memory

• Delay start for brew day programming

Off course the brewing application benefit of all common features

• Log of all process data locally in the EEPROM

• Push of process data via wifi to thingspeak server

• Download of process data via USB (CSV format)

• Web visualization of process data

• SamrtPID dedicated smartphone app for data visualization (android only)

If this is not enough the development roadmap foresse other uniques functions in particular the possibility to define the process parameter and recipe via web or smartphone interface and upload via wifi to the controller.
Even if it’s very easy to configure smartPID via local menu the possibility to have a web user area with all parameters and recipe as well all the log data of previous brew day we believe is a real plus. In order to simplify the recipe process from definition to run mode also import of mash and boil profile from major SW like Beersmith is in feasibility stage

In next posts we try to show a real case of set up and cabling for BIAB equipments and a video with complete overview of the functions trough the EMULATOR

It does look really interesting. Have signed up for the mailing list. At the right price, I'd be keen to order one for use with my Grainfather.

I'm working with a local beta tester to engineer SmartPID for a plug and play GF retrofit ..just unplugging the STC200 and connecting smartPID and you can benefit of full process automation (including pump) , recipe management, wifi connection and brew day data loging..etc

stay tuned

[Bridgey23]

Sounds good. Will be interested to see how it compares to the GF upgraded controller. Both functionality and price wise. As I was looking at purchasing that when it's released.

 

[arzaman]

SmartPID is not a simple controller or thermostat, is more an “open platform” powerful and flexible where the resources and I/O can be used for different applications, different environments and integration. My idea is to develop an ecosystem of “vertical” applications on top of a common set of features

the first two applications developed for homebrewer are

smart thermostat (or basic application) that is the base line for any thermal regulated process . Can be used and adapted where it's need a PID control or perform a retrofit o simple thermostat with something more advanced. Typical example is fermentation chamber

Smart homebrewing app that is focused on all brewing process automation from mashing to boilng from hop addition to whirlpool and cooling including recipe management

other applications you want to see on smartPID?

Working to a plug-n-play and easy retrofit solution to upgrade original grinfather controller with Smartpid and need some suggestions and ideas from GF community

The idea is to keep the original case and switches, just removing STC200 and rewiring Smartpid in order to get full process automation, recipe management, wifi data log, OLED graphical display, USB, etcetc.. and basically there a two options

1) connect heating element to relay 1 , connect pump to relay 2 in parallel to switch, connect temperature probe to one of the two control channel. Just two wires for pump and a screw driver !

You can benefit all the smart PID automation feature (including pump cycle automation) but the temperature control during step mash will be performed ON/OFF (with hysteresis) since is not advisable to use PID /PWM algorithm with mechanical relay output
Also during boil you lose the nice feature to control power via PWM 0-100%

2) insert in the case a solid state relay (10A minimum) to control heating elements, pump control and temperature probe as option 1

Little bit of extra work and a need of suitable SSR with heat sink to fit in the small spare space inside the case but you can benefit full PID + PWM solution either in mashing or in boiling

there is also a 3rd option more invasive that need to work on the base of GF separating 2 heating element now in series in order to control them separately (500W by PID during mashing, 1500 W by relay during mash in/out and boil)

what option do you prefer ? Any other suggestion ?

 

[arzaman]

Finally succeeded in retrofit the original GF controller with smartPID using the original wiring , connected heating element to relay1 and pump to relay2 (in parallel to manual switch). It’s not suggested to use PID algorithm with relay.. better to use ON/OFF algorithm with hysteresis but anyway you can benefit all the advanced features

as soon as I can I will post a full tutorial for upgrade and a brewday with the autmatic process control

[zeggie]

Ok, looks fine and all but what is the price going to be?

 

[SBOB]

Ok, looks fine and all but what is the price going to be?

especially considering the fancy new (plug and play, fully supported, app store app interfaced) grainfather controller is $199

 

[bus680]

This is just what I am after. If it goes into production I'll buy. From what I have seen so far looks really good. Great work mate.

 

[arzaman]

SmartPID is not specifically designed as GF controller replacement and is more a general purpose home brewing and process automation controller applicable in any brew rig as well as other applications (fermentation chamber just as an example) but I would just run a proof of concept of the retrofit and honestly is quite simple (in option one with no SSR) and maybe is good altermative.

I didn't run a full feature comparison with the new controller upgrade from GF (I see just some video preview) and for sure I expect they did a great job either on the HW and the SW also become they come after a series of other aftermarket controllers...so they have time to study

If someone is capable to add aslo a SSR (option 2) the gain in feature and functions from the original STC200 is really great
any idea or suggestions how to do ???


About costs...I can say will be cheaper…

enjoy

I can't believe I haven't seen this thread before. I reckon there is a heap of scope for this product.

All the electric brewery builds with numerous PID controllers and timers mounted to the front, hard switches, lights and such which take up a lot of room on the panel necessitating a large box. One of these could do away with multiple controllers and feed a couple of SSRs. On top of that the brew could be monitored and controlled from one's phone instead of a dicky set of menus. AND it logs data so you could literally check your ramps times and profiles during or after a brew. Winner.

Your kinds words reward me of all effort , investment and uncountable hours (night and day) spent to develop the product
Indeed I try to summarize many years of homebrewing experience, diy systems in something professionally engineered and productized

now running last mile..the hard one..to go live

stay tuned

arzaman, can this be used to control 2 vessels from a single power source? i.e. heats up the HERMS and when the HERMS switches off due to PID control it then immediately switches over the the HLT.

Not sure about your set up but with the smart thermostat app you have two independent PID channels

ie you use two sensors and two outputs (realy , SSR..) to control two set up point and process

hope this help your application

In the hombrewing application one channel is used for mashing/boiling etc with full automation and 2nd channel is used to control an heating element for the sparge water

this is an example of setup

hope this help and fits your application

[peteru]

I think the question is more along the lines if you can control total power consumption by having the two loads work in mutually exclusive mode.

For example, the SmartPID is connected to a 10A power source and has two 10A loads. You want to only run load A, or only load B at the same time, but never both A and B at the same time because that would cause overload on the source circuit.

Looks like it is now up and running.

Hi guys

I see that the breaking news is faster than me !

Yes smartPID is finally starts a crowdfunding campaign on INDIEGOGO
It has been very complex and demanding but at the end smartPID is now live



I see already some pledge from Aussie and traffic from the forum and your community and thanks to all early adopter and backers but now the most important think is to spread the news to reach the maximum number of people.
I have chosen the hard way “all or nothing” to reach a certain volume and MoQ to keep production cost and consequently price affordable and next days I will start some mkt campaign but the success of the campaign depends greatly on you and the world of mouth is the key..I kindly ask you to engage your homebrewing, DIY enthusiasts, makers friends an let them know about the campaing

sure of your support I will update regularly
