The motorhome that would not start in April
A motorhome has two batteries and they fail differently. The house bank gets emptied by something that switched on; the chassis battery by things that never switch off, over months, with nobody looking.
-
The only battery fault that gets hot
A charger that stops announces itself in a day. A charger that never stops takes a season and costs the bank. The current beside the voltage splits one alert into two very different afternoons.

Your hub went offline. Was it the power or the internet?
A hub cannot report its own death, so both failures arrive as the same silence. Four ways to tell them apart after the fact, and the wiring that stops the question being ambiguous in the first place.
-
Why the hub goes offline every time you pull out of a site
Usually it is only the campground Wi-Fi falling behind you. Occasionally it is a socket switched with the ignition, which makes every drive a blind gap and every winter a write-off. A two-minute test tells you which.
-
A sensor went quiet, and the card already knows why
Out of range, out of battery, or somebody picked it up: three causes, one symptom, three different Saturdays. Every clue that separates them is already on the sensor’s own card, in the last frames before it stopped.
-
The part nobody sells you
A sensor tells the hub. The hub has to tell you, and that second part is the one that quietly does not work. How to get a connection to your RV, including the storage case where it is hardest and matters most.
-
The coin cell problem
A sensor that has run out of battery does not tell you it has run out of battery. Why coin cells fail in the cold, why lithium matters, and why last-seen is a reading in its own right.
-
Freeze protection for an RV you are not standing in
A burst line is a five figure repair that announces itself hours after the temperature crossed the line. Monitoring does not stop the freeze. It buys you the hours.
-
Checking on a stored camper without driving there
Off season, the rig sits somewhere you are not. The two questions worth answering remotely are whether it is getting too cold and whether something is still running.
-
Three reasons the furnace quits, and only one needs a technician
Propane, battery or a fault: the interior temperature says the heat stopped and cannot say which. The readings that can are ones you probably already have, and they decide whether your morning is a fill, a plug-in or a phone call.
