canze-icon-shadingIf you want to learn about your Renault ZOE electric vehicle, you’ve come to a good starting point. We will supply you with an app that displays driving stats and lots of interesting information about your car. All you need is a Bluetooth OBDII dongle or a super fast do-it-yourself build CanSee dongle, and an Android device. For a more detailed description of the app see the about or the screenshot page. There is a sister project for Apple iOS.

The app is available on Google Play store here.

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”.

If you have copied the code for the Node-Red implementation of the Renault API, be aware that the the kamereon_api key has changed. A few clever people figured out they are distributed using Google Firebase instead of in the code of the app, so decompiling is now useless. However, it’s pretty much all over the internet now, so here is a link to as far as I could quickly follow back.

BTW, there are now many more implementations for Node-Red.

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.

With the addition of the Ph2 and the new settings it’s fair to say we were not up to snuff when it comes to app stability. In December we significantly went over Google’s “bad behavior” benchmark when it comes to app crashes. As written earlier, we’ve been daily checking and meticulously cracking these and older lingering bugs and mostly updated weekly to avoid those from re-appearing. I am happy to announce that this weekend we lost the red “bad behavior in the last 30 days” tag.

We continue to trace and if anything possible fix each and every crash we get reported and release those fixes within a week of receipt. This is by far the most important reason for seeing recent updates in the play store and we appreciate you installing them to keep user experience as good as possible.

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!
