I've followed in the footsteps of giants, porting the cmd2jura into an ESPHome component. I have then almost fully reverse engineered my Jura machine. I used ESPHome to create automations to step through the menu, make changes, dump and compare to baselines of EEPROM and RAM. From the results, I was able to create closed loop automations for my Impressa X9.
I am able to:
- read/re-write the brew counters
- re-map the buttons to different products and add new products
- dedicated decaf product buttons
- double brew of milk based beverages
- edit the recipes and preferences
- change the power on/power off schedules
- change auto power down timers.
- know which lights are on/flashing
- know when beans are out, water is low, trays are removed

all in home assistant - and also of course I can brew coffees and power on/off with a voice assistant.

There is even an EEPROM/RAM explorer web interface that documents/decodes the regions of RAM/EEPROM I've figured out which allows sending the UART commands directly.

I would like to support other machines - alas I don't have other machines or the time. This hyperfocus is also waning. The integration does everything I need at this point.

I’m trying to get a better picture of how well EVSE manufacturers actually support their hardware in Canada after the sale—particularly when the problem involves firmware, configuration, cloud services, OCPP, replacement parts, or engineering-level technical support.

This came up because I’m currently dealing with an Autel MaxiCharger that appears to have a firmware/control issue. I’ve been able to gather fairly detailed diagnostics, and Autel initially escalated the issue to L2 support. After learning that I acquired the charger second-hand, however, their response shifted to warranty eligibility rather than answering the technical questions I was asking.

I’m not trying to turn this into an Autel-only thread, though. I’d like to understand whether this is common across the Canadian EV charging industry.

If you own, operate, install or service EV chargers in Canada, I’d be interested in hearing about your experience with manufacturers such as Autel, FLO, Grizzl-E/United Chargers, ChargePoint, Wallbox, Emporia, ABB, SWTCH-supported equipment, Tesla, Eaton, Siemens, EVBox, Webasto, Bosch, or others.

Useful details would include:

-Manufacturer and model

-Residential or commercial installation

-Approximate age of the equipment

-Whether you were the original purchaser

-Whether it was privately purchased or installed through a rebate/grant/incentive program

-What failed or what assistance you needed

-Whether first-line support could actually troubleshoot the problem

-Whether you were able to reach engineering/L2 support

-Availability of firmware updates or firmware recovery

-Availability of replacement parts

-Whether the charger could be locally configured without the manufacturer's cloud

-OCPP interoperability/support, if applicable

-Whether support continued after the warranty expired

-Whether support continued after ownership of the charger changed

-How long resolution took

-Whether the manufacturer ultimately fixed the problem, replaced the charger, or left it unresolved

Positive experiences are just as useful as negative ones.

I’m particularly interested in cases involving infrastructure that received Canadian public funding or incentives. Canada has spent substantial public money encouraging EV charging deployment, and I’m looking into whether those programs adequately consider the long-term supportability and service life of the equipment, rather than simply whether a charger gets installed.

I may use the overall findings to support questions or submissions to Canadian government agencies about EVSE lifecycle requirements, repairability, firmware support and manufacturer accountability.

If you’re comfortable with your experience being quoted later, please say so. Otherwise I’ll treat comments as background only. Please don’t post serial numbers, addresses, account information, API credentials, or anything else personally identifying.

I’d especially like to hear from installers and commercial charging-site operators who have had to support multiple brands over several years. Which manufacturers are still responsive once the installation is complete—and which ones become difficult to work with?
