Sure, I’ll leave you a link to download the MIK app.
MIK APP
You must have ADB running.
It’s a dashboard that can replace BYD’s Dlink, so I don’t recommend it.
It allows for a lot of customization for the car, but in my case, I only use it for MQTT.
You have to configure the app to start with the system.
The app is all in Chinese; you can use Google Lens to help.
Sorry, I don’t have any screenshots to upload right now. Go to the last configuration option and find the MQTT section. In my case, I started the tests by pointing the Home Assistant IP to the Mosquitto addon in HA locally. Once it was working, I opened a port on my router and sent it over the internet.
The app communicates when I turn the car on and off; during the trip, it doesn’t send information.
In HA, I created the sensors manually, using AI. The sensor template may vary depending on the car, but they review it with MQTT Explorer and adapt it.
Tips:
I have automations with a summary of each trip, a service notification when the mileage is reached, and a notification to charge it when the battery is at 25% or less, etc.
I’ll upload some images of the MIK app later.

Did you manage to make it send data periodically or it only sends on turn on and turn off? Also how did you enable it to autostart but not replace the bottom controls?
In the tablet’s settings, in the applications section, you can specify any app to run at startup. It’s a toggle switch; disabling it will cause the app to open automatically. That’s all that’s needed. MIK runs in the background. During MIK installation, you have to accept some permissions it requests. As far as I could tell, MQTT messages are sent when the car is turned on and has a connection, and also when it’s turned off. The app has the potential to send real-time data; it reads a lot of information from the car—speed, RPM, battery level, coordinates, etc.—but unfortunately, it doesn’t send it via MQTT. Were you able to install the app and configure MQTT? Regards
Thanks so much for this! Had to change some values around for my atto I wonder if it’s country/region specific in terms of how the mqtt messages are published but seems to be working now.
My only other problem is to get the BYD to connect to my home wifi instead of the phone when I start up and switch over the home wifi as soon as I get home and before I turn the car off. Any suggestions there would be greatly appreciated

I’m glad you tried it and it works for you!
In my case, when I start the car, it automatically connects to my home Wi-Fi, but I have an app on my phone that automates turning on the hotspot. So when I leave home, it switches from my home Wi-Fi to my phone’s hotspot.
The app is called Automate for Android.
Do you have a link to the integration you used?
Created an integration on smartcar.com (used free tier) created a second “authorised account” via BYD app as per smartcar instructions.
In HACS added smartcar and linked it.
I’m going to say if I can do it anyone can do it!
The free version on smartcar has some limits but I’ve achieved what I have been trying a year to achieve

But they’ve recently opened the free tier up to include webhooks which is a huge plus!
Ah nice! Unfortunately they don’t cover Australia. 
The values of smartcar will not be refreshed in home-assistant?
Yes but it seems on the free tier, not enough. Early days
Maybe I don’t understand your question, but of course they’ll be updated.
The docs explain better, but briefly:
- The integration allows for polling for updates every 6 hours
- If you enable webhooks, it will not poll for updates
- You can customize polling in either case (and disable the default polling if you’d like)
It’s all in the docs, but if it’s unclear, open an issue or PR and I’ll work with you to improve it!
ok. now its clear every 6 h hours. hmm thats less.
I’m working on a webhook integraion

Looks like someone has created an integration for A Better Route Planner. It’s still early, but seems cool.

How does this work exactly? Can you install the app on an Atto 3 to access data such as SoC etc.? I’m in Aus so hopefully it’s available to me
After using it (rate limited) for a few months, EVLinkHA using evlinkha.se has stopped working on Dec 10.
I get " EVLinkHA Vehicle Status Error : Unexpected error 503 when trying to fetch vehicle status." messages and it looks like https://evlinkha.se/ is no longer reachable.
That’s a shame as it was a great solution.
