Getting ready to do a water run with my Brew_Pi Spark. It will be running a commercial glass door cooler with a 200 watt heater added. Pictures soon to follow. Any first run pointers and or settings that I should be changing ?? This build was reasonably easy as I have been in process control for a lot of years. Thanks in advance !!
I think the default settings should be a good start for that setup.
One you have some data and can share a graph we can fine tune.

Wanted to set the IP in the BrewPi server using this from the setup instructionsâŚ
Using âsudo nano /etc/network/interfacesâ
auto lo
iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
auto wlan0
iface wlan0 inet static
address 192.168.0.6
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 8.8.8.8
wpa-ssid âYOUR_SSIDâ
wpa-psk âYOUR_PASSPHRASEâ
Changing to my static address of 192.168.50.9 and of course my SSID and passphrase.
I think it is ctlr x and them Y to save. Stop and restart using
âsudo service networking stopâ
âsudo service networking startâ
After doing this the IP address still comes back as 192.168.50.219 coming from my router.
Not a show stopper to do a water run (tonight, I hope) but would like it to be static.
Any thoughts on what Iâm doing wrong ?? Thanks
I recommend leaving the IP on automatic from DHCP and configuring a static lease on your router.
That will be much easier to handle if youâre router configuration changes.
Okay, Iâll have to investigate static lease on my ASUS routerâŚ
Checked it out and will give it a try. Looks to be easy on this router.
Thanks for the quick reply !!

So, water run went without a hitch. Control was very tight within ~ 1/2 deg F. Doing beer this weekend. Having not used Brew-Pi I came up with a question⌠In between runs of beer do others shutdown the Raspberry Pi server and Brew-Pi ??? Or is there an idle mode that it can be set to ?? What do others do ???
If you set the mode to OFF and stop the current brew, thatâs no cooling/heating and no data logging.

Jep, just stop the current brew. I turn off the Pi in between but be sure to shut it down properly instead of pulling the plug - it can corrupt your SD card!

I have another question⌠I think I read somewhere that the outputs are good for a certain mA output. I have these relays that I would like to use a Brew-Pi output to turn on the lights in the cooler. So will these work ??
Only 20 mA. I highly recommend using SSRs instead of mechanical relays. If you are using mechanical relays, you should also use a diode to protect against back EMF that could damage the output.

Today question⌠Running the first beer batch and holding temps perfectly !!! Using my beer profile âNew England IPAâ and seems to be running it. Question is on the top under the Brew Pi logo it says fermenting âTESTâ. Shouldnât is say New England IPA ??
Otherwise, running great !!!
It seems you didnât start a new brew. Where is says âtestâ is where you can choose to stop or start a (new) brew. You could do that now if you wanted.
By the way, in the temperature profile, you donât have to set a temperature each day but you can choose longer period!
You can do something like 68 degs for 3 days ?? I wasnât aware of that. No big deal with the fermenting name, Iâll remember to start a new brew next time. Thanks for the help !!
So here I am 2 days in⌠Iâm thinking this looks real good ?? My error at the start, day â0â had no temperature value. since then, I think it is working as it should. Any comments / suggestions ???
The profile is a combination of points. It will interpolate between them. You can also enter 1d2h.
Not sure what you mean⌠1d2h as the display of the graphed data ??
