What we are actually building, and why
We built this because we kept driving back to check on the dog. Everything about how the product works follows from that, including the parts that look like missing features.
-
The temperature check you cannot make from a trailhead
A parked RV on a mild day can reach a hundred degrees inside an hour. This is the maths of that, and what monitoring does and does not solve.
-
Nobody at the office can reset your thermostat
Whether the pedestal still has power decides everything: the campground can fix one of these in five minutes with a breaker, and cannot touch the other. How to know which you have before the thermometer catches up.
-
Two thresholds and a clock
A rig at 82 and holding is a different animal from one that was at 74 twenty minutes ago. Nothing measures a slope, so two thresholds and the gap between them are how you read one.
-
How to tell the power went out
Six ways to know the pedestal died, what each one costs you in delay and false alarms, and the pairs that tell you what actually happened rather than just that something did.
-
104 volts, and nothing tripped
Surges get the attention and low voltage does the damage. What a sagging pedestal looks like on a chart, what a miswired one looks like on the first poll, and why the EMS rather than the alert is what protects the rig.
-
The charger stops, and you find out next spring
The converter, the solar and the alternator all fail the same way from the battery’s point of view. Why “alert when current goes negative” fires every night of your life, and the rule that works instead.
-
Set the floor where morning is soon enough
A battery threshold is a decision about when you want to be told, not about when the battery is unhappy, and almost everybody sets it too low the first time. Where the floor goes by chemistry, and the ten-second sum that turns a percentage into hours.
-
The generator started. The transfer switch did not.
Nothing we read knows a generator exists, so every method here is inference. One pairing still catches the expensive failure: the set ran for four hours and the coach was never connected to it.
-
The pedestal is fine and the rig is dead
Three readings, in order, and the answer is usually immediate: is the post alive, did the EMS choose this, and how much of the rig is still drawing. What they decide is which direction you walk.
