10-20A bluetooth smart charger recommendations

I have an old single stage charger in my RV. I want to replace it with a 3 or 4 stage charger. I only have one Group 31 battery, so a charger in the 10-20 amp range should be plenty good.

If at all possible I’d like bluetooth monitoring so I don’t have to whip out the old multimeter every time I want to check my batteries.

Any recommendations?
