CanZE is now available in the Google Play Store. Once installed that way, updates will come to you a tiny bit slower, but fully automated. We will maintain a weekly release schedule as long as features are changed or added as frequently as they are now. When we’re confident that the updates in the Play Store come through fast enough, we might close the download page here.
We were able to shed a lot of code that was no longer necessary, meaning easier to maintain, and less error prone. We hope to have added again a bit of stability.
Also, we have gained a lot of information about the Zoe this week, straight from Renault. Consequently, we also now know that a few things in CanZE are simply wrong. Friction braking is far smarter in the car than we anticipated, and that code needs to be rewritten. The information came in too late to make to this weeks release, just know that the friction braking bars are not correct for now JUST made it in time for today’s release.
Also, the firmware screen was unfortunately picking up a wrong field. This has been corrected, but of course we need to work on reference versions again based on your input. Please do report newer versions if you see them in your car.
Today I have spoken with a Renault specialist and to make a long story short: my definition of friction braking is WRONG. In normal operation, the brake system is entirely “fly by wire” and does not perform friction braking as CanZE reports. I will fix this, but I doubt it will make this weekend-release. Long story short, Zoe uses far more motor braking than anticipated. To be continued.
The weekly build we have coming up for you is mostly one of serious un-cluttering. We have moved all experimental and playground stuff out of the way and to a new screen. This can be accessed through the “three dots” menu, just next to the settings. Developers now have each have their own playground. Go there at your own risk!
A very nice enhancement is that time-plots are now saved, so their data is not lost when switching screens.
The driving screen now displays a real time kWh/km. I’ve been running this for a few drives and I’d say it is more pressing than the raw kW in the dash. Quite the eye opener!
For the UK drivers, there is now a “Miles” tick in the settings screen, and it already works for the text based screens.
Maybe somewhat boring but still worthy news is that we have significantly stabilized and speed up ELM again. And as we’re getting more confident about CanZE restoring order when things go wrong, there is now an option in the setting screen to change the log level, enabling you to get rid of those blasted warnings popping up. For the daring, builder people, the Due based hardware is getting more integrated too and is VERY responsive. See Bob’s blog post below this one.
We discovered that Firmware versions can be dependant on the hardware version of certain components. We’re not ready to take up that challenge for several reasons. Just know that the dealer might be right if he tells you that really no, there is no update for your car while CanZE says there is.
We have exciting features in this weekly release. Most are a bit under the hood, but you will notice them anyway.
ELM327 stability has improved a bit and it is a little bit faster too. As I mentioned last week, we’re shaving and modifying there in tiny steps. It might be a tad more talkative when things go wrong.
Behaviour when CanZE goes out of focus has improved a lot we believe. In essence, CanZE is paused and communication with the ELM or other device is stopped.
A few timed graphs have been added on request, i.e. state of charge over time.
The driving screen now has a function where you can add the distance to destination, and CanZE will update you on the expected distance available in the battery on arrival. You can also choose to double the distance to destination when planning for a round trip. Just tap the “distance to destination” line to get a pop-up.
A feature that we really like is that the last values that were requested from the car are now retained so you can open all the screens even when not connected and they are showing real information.
Stay tuned and don’t forget to report issues, or requests on gitub.
