No I do not, I have a pretty good feel for the amp hour draws of the devices I use. I wouldn't mind a nice BM but it is low on my priority list of items I need and a good one is pricey. I've been successful in just monitoring voltages for a ballpark SOC for the last few years.
The Victron android monitors software in float mode gives me a good representation of current draw during the daytime, as I have enough solar normally to cover all loads without drawing from the battery at all, so i get a live picture of current drawn. I can look at the watthours used overnight to get a good idea of amperage usage overnight and subtract that from my battery capacity to see how much I used. For example:
