That's a nice meter and I may buy one buy even though my Fluke gives me all the precision I need.
For me: I plan for and know my battery status before bedtime. So short of a very rare battery failure I have no desire for a voltmeter to be viewed from the bed. And observing the voltage to the millivolt level is not meaningful due to various DC draws that run and vary day or night.
Some said equipment that uses DC and varies in my rig: refer, hot water, furnace, AC/heat pump, thermostat. In addition there are other draws like: smoke detector, CO2 detector, light control circuits, the Trimetric, solar controller and there is more... Not to mention any outside lights that are left on for safety... Even the inverter/charged has a DC draw with/without AC available.
That said it could be useful to learn those typical draws and observe that the voltage drop/rise at night doesn't exceed the norm. But not for me in bed, if something makes we wonder about a problem I'll get my as* out of bed and look at the Trimetric which tells me voltage, amps and SOC.
My take and my style.
However, from an educational perspective great thread, thanks Mex.
