Growth has slowed down a bit but that doesn’t mean we’re not baffled to find our app on so many devices! This week we broke through CanZE being installed on 9000 devices. Google’s definition is: “The number of active devices that the app is installed on. An active device is one that has been turned on at least once in the previous 30 days”.
Quick update. Last week saw a huge 3.4% uptake of users, or more precisely, “devices that have been turned on in the last 30 days and have CanZE installed”. This is twice the usual uptake in a month! As a result, we’ve handily past 8.000 users. I have not taken the effort to investigate if there is a specific reason such as a review in a popular channel, but in any case: Thank you!
Allow me to also do a mild vent. Reviews on the Google Play are very often super positive which we of course appreciate a lot, but now and then somebody slips in a 1 point rating with a “It doesn’t work with my car” review. No details, and never a response to a reply (which we always do). I checked, and Google Play does a notification on the device if a reply by the developer is issued. It’s a very frustrating endeavor. So, if you ever run into an issue, please report it on github: we do take pride in ironing out kinks! Feel free though to direct praise to Google Play 😉
Speaking of kinks: almost a full week with zero crashes now. Fingers crossed.
Thank you “Silent Energy”
While we’re certainly not done untangling the ZOE ZE50 and new ZE40 (together called ZOE Ph2), we’re pretty confident we’ve cracked the basics fairly well.
ZOE Ph2 is a significantly different car than the old models and required additional code to access the car’s computers. We had to make changes in the CanSee dongle and the ELM327 (KONNWEI) dongle driver has much improved, also performance wise. And once again, lots and lots and lots of testing in cold winter nights on driveways, city streets and even road trips. While all this was going we’ve also been doing some internal refactoring to facilitate the different models in a less cluttered way, together with an improved process to do our research, read, finding the fields we need to make CanZE do it’s thing. All this despite the modest outside looking the same, so maybe we’re more impressed than you are!
Having said all that, our short term effort is clawing back on decreased stability that was introduced by all the code changes made in the last few months. Crashlytics which anonymously provides post-mortem information is a huge help and as I write this, all known crashes are tackled either in the current production release or ready for the next release, so please do update if you haven’t already. You, the thousands of end users are the heroes doing the cold harsh field testing. Thank you for that.
So what’s the speculative part? Well, with the Twingo EV now on the market we’ve had a bit of time to take a look and we can possibly make it work. This is not a promise: history taught us we couldn’t make the ZE50 work until enthusiastic and knowledgeable team members actually owning these cars were co-developing. But with above changes and already one enthusiastic tester in the field, we might just crack it. Still, it’s a tough cookie with slower research cycles. But who knows? If it works we could maybe add say a Twizy the same way? Even more speculation!
- looks like we have solidly past 6200 users. A user is defined as having the app installed on at least one device running under it’s account, for somewhere in the last month. It is not a run metric.
- Guess what I have on my driveway now on loan for a full week. Watch this space……..
- I have understood that most TPMS functions are available on the ZE50 natively. Would it be prudent to disable them for a ZE50? Or asked differently, is there anything a ZE50 needs regarding TPMS that is NOT already natively in the car and that we offer today for the earlier models?
Anyone who has played with the Research facility, or any log file really, knows the results can be massive and hard to process.
Massimo Ceraolo made a small post-processor that splits up the data per field, timestamped from start-of log. The output files (one per field) are pretty easy to convert into plots with Excel or other programs.
Thank you all for installing and running no less than 5000 CanZE instances on Android! A humbling number for a total amateur project.
In the next release you will notice some UI changes.
- All screens will now have an Android style “Home” button, a left pointing arrow left of the title.
- The main menu will no longer display the settings icon in the title. In line with conventions Settings has moved to the Three-dots menu.
- The OK and Cancel buttons in the Settings screen are removed. Either pressing the Android return button at the bottom of the screen or the new “Home” button left of the title will save the settings and return to the menu screen. However, you can still Cancel using the Three-dots menu.
- “Please wait” type of messages are being gradually replaced with a blue spinner, i.e. when opening the setting or when fetching all data.
This draws CanZE a little bit more into Android UI conventions and should make using it slightly more intuitive.
We have an exciting new release coming up in a few days. Next to the inevitable bug fixes, we have a few new features we think you will love.
- In the technical section, there is now a separate screen for the 12 volt battery. You can monitor here the voltage of the battery over time. Maybe we need to add current later. We’re not entirely happy about the color coded status lines, indicating charging and car status, but it was a needed compromise at this moment to show the changes in time.
- We have slightly modified the consumption screen. We removed the capacity in Ah from the upper graph and replaced it with the SOC percentage from the lower graph. In the lower graph, we added a gradient representing the difference between real distance traveled and the change in the range indicator. It starts in the middle and will go up (red) if the range indicator decreases more than the distance traveled, or down (green) if it decreases less. We believe it is much more useful because it indicates if your initial planning, whatever that was, is still on track. If you love the old version, it has moved to the experimental section. We might depreciate it later though.
- There is an experimental option to make a raw dump of all the frames we use. We need both your help and this activity to check out reports we’re getting about weird values when CanZE is used on Q90 and R90 cars.
Stay tuned and feedback, as always, is much appreciated.
