Is 0.2.8 out now? My girlfriend wants my spark off the dresser and into the brew shed!
Itās done, together with a big update to the script and the update process.
I am just holding off release until morning so I can monitor it.

Iād love to know the connection between a software release and you keeping your brewpi spark on the dresser. I canāt imagine how they could possibly be related 
Well, Iāve been playing with the pi in our room because there is a TV there to hook it up to. I promised it would be out when the update came 
Isnāt your wife going to be upset that the spark has left the bedroom? 
hehehe 
On topic: new firmware is out!
Itās great that 2.9/2.10 were released a couple of days ago to fix some of the bugs but will the feature releases destined for 2.9 still be happening today or are you now behind on those? Iām not sure where else to go for updates in this respect. I think this was something Dean was getting at previously, there is nowhere for the layman brewer to go and see this info clearly. I purchased this mainly for the ability to be able to switch on the HLT and monitor it remotely, the fermentation chamber side Iāve been using the age old STCās for a long while but this device, I see as something new and special with many benefits as long as the software actually delivers.
Luck and Cheers.
I was thinking the same!
We bumped the version number earlier because of these bug fixes, PWM support is still part of the next feature release. Yes we are a bit behind.
I have already written a PWM actuator class and the unit tests to verify it works, but have not integrated it in the temperature control algorithms yet.
If you can read code, look here:
https://github.com/BrewPi/firmware/compare/develop...feature/pwm-actuators?expand=1
The class manages that even with infrequent and irregular updates, it still maintains the correct average duty cycle by adjusting the toggle moment for each period. Output of the unit tests looks like this:
*** Results running 100 periods and random 0-500 ms update intervals,with duty cycle 100 and period 10000 ***

My hands are tied at the moment, because tax reports are due at the end of the month. I hate accounting and I really want to jump back onto software development.

Fantastic update, Iām watching dutifully as I would like to use this as a full brewing controller!

Hi Elco,
Are we getting the features expected 2 weeks ago in the release that should be this weekend?
Cheers.
I take it thatās a no??
Yes, that is a no.
I can not devote my time to software development 100% of the time.
This week I had tax report deadlines and had to spend all my time bookkeeping. Matthew had a big deadline for his work at Spark, but should have more time in coming weeks.
I have worked 80 hours this week and thatās all I can do.
The required changes to the code to support mashing are big, it requires a complete refactoring of the temperature control algorithm. I have started doing this, but it is not ready for release and it will probably not be for 2 weeks.
I will have a lot more time to code this week and I will work as hard as I possibly can to implement PWM actuators, mashing and pave the way for multiple control loops.
If you think it is taking too long, I have no problem with taking the hardware back and giving a refund.

Whoa, donāt burn yourself out!! If itās not ready, then so be it. This isnāt a life and death situation.

Hang in thereā¦ weāre all looking forward to the new code, but understand things take time. As BeerGrylls says, donāt burn yourself out! Good things come to those that wait!

Iām in for the long run, you guys do great work. BeerGrylls you couldnāt have said it anybody, itās not life and deathā¦
These posts reflect the reason I started this threadā¦ We all want to help, buy products and support this great project. We are brewers and geeks after all.
But the issues arise when users either feel misled or confused by stated deadlines and features that get missed or simply through confusion by knowing what is going on.
Everyone is on your side @Elco! They just donāt always know what is going on all the time 
Good communication to your customers costs almost nothing and will gain you a lot. Keeping them in the dark then ranting at them when they ask for an update will do you no favours.
There has been no real communication on progress since a rough schedule was posted at the beginning of April. A quick note to explain you are behind but are still working towards it is just common courtesy for your customers/supporters.
This product is good and has the potential to be amazing and a market leader. If you are struggling with communication then maybe ask for help from the community instead of isolating them.
thatās barely over a month and they regularly post on the forums I think youāre just being impatient, their customer support and customer service seems to go way beyond that of other start up products Iāve experienced.
I think you need to cut them some slack and be patient, look and the developments that have happened over the last few years, brewpi is constantly evolving and just have confidence that theyāll come when they ready.

It was stated there would be releases every 2 weeks, I was just asking for an update as the releases didnāt happen and there were no communications on it. I donāt see how that is impatient or unreasonable in anyway. To be honest I couldnāt care if it takes a couple of months to get the next release, all Iām asking for is simple communication to that effect. Itās all about managing expectations.
