I’ve been getting battery percentage on my ST-903 for several weeks now.
Awesome, thank you for the effort!
I had to delete and re-add them in Ruhavik.
I’m also using ST-901 and I don’t see the battery percentage yet.
Did you plan to implement battery percentage for all Sinotrack models?
Also, please consider adding the ST-903 explicitly. It works as an ST-904 but less guesswork is always better.
