Dolphin EON 100

[josgaming]

Hello,
I bought a Dolphin EON 100 pool cleaner that uses the Maytronics One app instead of MyDolphin.
Is compatibility with this model planned for the near future?
Thanks

[elad-bar]

can you pls try now with the latest version and report back?

thank you

Integration setup looks successful but no pool robot is detected. The robot is properly associated to my Maytronics One account.

I connected with my emaiil address which has both a MyDolphin Plus account and a Maytronics One account. The integration connects successfully but the EON 100 is not detected. The robot is only linked to the Maytronics One account. It seems the integration connects to MyDolphin Plus but cannot reach the Maytronics One API to find the robot."

i changed a bit the snippet provided by @yumlevi to test the authentication with otp so it will support Maytornics One, please run it and tell me whether it works,
if it does work, i can release a version of the integration for you to test for Maytronics One app.

If the test script worked, the next step is to test the Home Assistant integration branch that adds Maytronics One support:

https://github.com/sh00t2kill/dolphin-robot/tree/maytronics-one-support

Manual install steps:

1. Download the branch as a ZIP file from GitHub.
2. Extract the ZIP file on your computer.
3. In Home Assistant, go to Settings -> Devices & services and remove the existing MyDolphin Plus integration entry.
4. Using File Editor, Samba, SSH, or another file access method, go to your Home Assistant config folder.
5. Back up and then remove the existing folder:
   custom_components/mydolphin_plus
6. Restart Home Assistant.
7. From the extracted ZIP, copy:
   custom_components/mydolphin_plus
   into your Home Assistant config folder, so the final path is:
   config/custom_components/mydolphin_plus
8. Restart Home Assistant again.
9. Go to Settings -> Devices & services -> Add integration.
10. Add MyDolphin Plus.
11. When asked which app you use, choose Maytronics One.
12. Enter your email and complete the OTP flow.

Please let me know whether setup completes and whether the robot/entities load correctly.

Thank you.
"Authentication works and refresh token works. However the robot is not detected — Sernum is None and I get ROBOT_SERIAL_IS_EMPTY, even though my EON 100 is properly associated to my Maytronics One account in the app. The robot is not the issue as it shows correctly in the Maytronics One app with the same email address .

I cannot test the manual install as I don't have easy access to my HA file system. I'll wait for the official HACS release. Thanks for your work !

[elad-bar]

If you are getting this error, no need to continue to the beta branch it will not work as well,
Will check more and get back with script adjustment

[elad-bar]

i had a meeting today with Maytronics, it seems that we need to use bit different endpoints, will get the details soon, hopefully the week after next week i will get to work on it.

[josgaming]

Thank you very much for your help !

[sebagsm]

the main problem is the shitty Maytronics One app. it keeps logging out, and it also unpairs the robot from the account.

[elad-bar]

I will try forward the complaint to the team in Maytronics, since the dissociation from the app is something thay happens to you, i'm concerned that the integration will not be helpful for you,
Since it relies on the fact you have paired device to the account

thanks :) if you need some testing for your addon just let me know
