Hmm here’s the screen shot from this morning, the fridge without a beer in, just set to stay at 4.5 c
Capture of my greenpi
There are a couple of things to note..
The beer sensor trace dropped out and didn’t restart.
The Temperature box is Blanked
When enabling the room temperature the graph doesn’t rescale and won’t go full scale even when refreshed.
This was captured using safari on my mac and I couldn’t see how to manipulate the graph, unlike when I looked at the Green BrewPi interface using my iPad, I could manipulate the graph to my hearts content, pinch, drag etc it worked fine, .. too much bias towards mobile devices ?
Tonight it’ll beTime for me to track down that commented out line in the Beer-chart.js file to re enable the range selector bars and possibly look to see why the beer sensor isn’t re enabled !
After looking through the code for the arduino the beer sensor will only get restarted if its in mode is beer (profile or constant) hmm i’d still like it to restart and log the beer temp ! Although maybe thats my autistic side coming out, if it’s stopped when it was going, get it going again even though it’s not really needed, I think i might have to see if I can live with that one…Although what if you want to log in the off state to see what heat gets generated by the yeast activity ? Maybe i’m pondering too much on the inconsequential !
Just updated my GreenPi system with the rev c shield to the latest 0.3 version.
At first I did an update/upgrade to the system and then installed the update tools and ran the update script. this worked well, although when it asked for a username to pop changes to my system I was slightly fused. I just hit enter and let it go. the script updated the software on the Pi and when it had finished I then reflashed the Leonardo to the latest firmware. After a restart my usual web interface appeared as the update script had preserved my changes to index page and beer panel, the downside was I still was using google docs for the brewing profile, so I Decided to run the install script in the tools directory. Nice new interface then appeared compete with the new localised Beer profile, Nice, really nice, a lot of effort has gone in , but my simple changes to show the system name was now gone, I thought this was going to be incorporated into the code base a while ago but hay ho, easily put back, probably my fault for not being vocal enough as I’ve been absent from the Brewpi forums for a while, but it does mean i’ll have to spend some time and effort to GIT and try and incorporate my changes, it probably won’t happen, family life & all that…
hmmm where was he code to put the zoom sliders back onto that graph?
My first impressions are that its oscillating a bit in Fridge mode, should I leave it or reset to defaults ? I’ll leave it overnight to see what happens… if its still oscillating then I’ll blat it …
Well that was a successful Brewday. The coin was tossed and A Black IPA was made .. The brew didn’t quite go as planned what I Thought was a 1/2 bag of crystal Malt was Biscuit Malt so I subbed Black Malt into the mash instead !
Recirculating the Black IPA
After listening to a Beersmith podcast on American IPA I decided to keep the mash temperature down to 64.5 and mash for slightly longer so the OG came out at 1.066, Slightly lower than the estimated 1.072 but hopefully it’ll be nice and light…
Sunday was transfer day / dry hop time for the Aussie Citra. Dry hopped with 21g of Citra i’ll leave it for 3 or 4 days and then Keg it ! OG 1.050 and at the time of transfer into the Secondary it had dropped to 1.010, so it’s 5.2% and i’m looking forward to it.
Since i’ve introduced the second fridge into my BrewShed, I seem to have had nothing but trouble with the BrewPi’s ! My latest woes have been with what is normally my rock solid Black Pi system ! The beer sensor has started to disconnect I’ve tried two during my latest brew and both have disconnected at random intervals. The GreenPi system also keeps disappearing from the network…
I hink the newest fridge addition is the most likely culprit and might be in need some extra suppression …..
4 drop outs into idle mode
Hey after posting on @BrewPi forum it looks like I found a Bug in the update temperature code
This morning I managed to get 20 bottles full with 7.82 % Bastogne/Trappist Ale, the rest went in to the Keg. OG 1.080, FG 1.020….
Looking forward to tasting this in 3 or 4 weeks time.
Yesterday there was a nice new REV C BrewPi shield kit waiting for me when I got in from Work. Elco was kind enough to also send me a bare Rev B Shield PCB to build up, which, once I manage to get it up to our Technical Support Services SMD facilities and build it, I plan to hack around and play with on the mega2560 and the I2C displays Piccies to follow when my phone is charged
Yesterdays #BrewDay didn’t go without it’s problems ! I need to sort out the mesh in the bottom of the Mashtun, either that or get another Stainless Steel mash Tun with a better fitting False bottom ! The grist came past the edges of the mesh and blocked the copper tube filter plus the Weight of 9Kg of malt didn’t help ! Then in the Last 1/2 of the boil the thermal trip on the boiler kept cutting out so boil was at 88c… In the end the contents were dumped back into the mash tun and the boiler bottom was removed and the trip bypassed The boil then resumed…
Took longer than anticipated but lets hope the Trappist/Bastogne ale comes out ok
OG of the Bastogne 1.080 which is pretty close to the design value of the Beersmith recipe
Now what temperature should i throttle it down to ? don’t want too much of that banana in there …
I had planned to have a brewday on this Bank Holiday Monday, but instead I’m having a Social Day… Something has aggravated the old Back. The recipe was to be this..
Although Since I was having trouble getting the Bastogne Yeast, I had to settle for
White Labs WLP500 – Trappist Ale Yeast
Once in the FV I was going to keep a tight control on the temperature as it’s rumoured to a bit unwieldy , we’ll see …
Thats if the yeast is Ok as it’s been stored in the fridge for 3 weeks whilst waiting for Orange Peel !! Hopefully i’ll get to it later in the week or next weekend
I have also been tweaking the BrewPi web code to show me which system I am looking at. I have changed the hostname of each system, found in /etc/hostname and also not forgetting to change it in /etc/hosts .. I have two RaspberryPi controller BrewPi’s, one in a green Case and the other in a Black case so naturally they’re greenpi and blackpi I changed line 29 in the beer-panel.php to
<span id=”beername”><?php echo gethostname();?> Is Fermenting: <?php echo $beerName;?></span>
and also changed the index.php line 39 to be
<title><?php echo gethostname();?> reporting for duty!</title>
