↳ The grey tank is full, by the way.
A monitoring system that answers the questions that actually matter when a parking lot is your neighbourhood — no subscription, no cloud, no yacht prices.
LandYacht is a modular automation system for converted vehicles — vans, Sprinters, skoolies, buses. Built around a chip-sized brain and a network of cheap wireless sensor nodes, it answers the questions that actually matter when a parking lot is your neighborhood: how much battery do you have, is the water running out, and is this thing level enough that your coffee stays in the cup.
It runs entirely on hardware that costs less than a campsite with a shower. It requires neither a monthly subscription nor the spiritual surrender of connecting another thing to someone else's cloud. It does not care what kind of battery, solar charger, or life philosophy you arrived with.
For the growing army of van and bus dwellers who are nerdy enough to want real data but too broke and too stubborn to pay yacht prices for it.
Independent nodes cover every corner of the van. Each publishes to its own MQTT topic and is reachable over WiFi for firmware updates. Swap one out — the rest don't notice. The first three are running in a real bus today; the rest land one node at a time.
Every sensor node runs on the same board — one spare part covers the whole system.
The same sensor data appears wherever you need it. Each display runs independently — if one goes down, the rest keep running.
A $10 touchscreen mounted in the dash. Always on. Tanks, temperatures, battery, leveling — with a plain-English bubble level and one-tap calibration. Works with no internet and no phone.
Served straight from the brain over the van's own WiFi. Installable as a home screen app — no app store. Remote access from anywhere comes with the optional Pro tier.
Battery, tanks, and temperatures logged on the brain itself. 24-hour, week, and 30-day graphs right on the dashboard. Understanding the van as a system over time.
These aren't mockups — they're real screens from the cab display, pulled straight from the repo. Which is public now, so you can check.
At the center of LandYacht is one small board — the brain. No Pi, no cloud, no subscription: the whole nervous system runs on an $8 chip that sips half a watt. It doesn't join your network; it is the network.
Pro tier — optional
Want remote access from anywhere, or years of archives instead of a month? A Raspberry Pi can join as a passenger — Tailscale VPN, big storage, cameras someday. The core never depends on it.
The system is complete without it.
These are load-bearing. They define what LandYacht is and what it will never become.
Any node can fail, be replaced, or be skipped without touching anything else. Consolidation feels efficient until it breaks.
Change the hardware, keep the topic. Change the dashboard, keep the topic. The topic structure is the only interface that matters.
Every node is useful on its own. The fuel gauge works without the Pi. The cab display works without the web dashboard.
"VEHICLE LEVEL" not "pitch/roll". "SEALED" not "servo state: 0". The driver is not a developer.
Every component can be sourced independently. Every service can be replaced. The system outlives any single supplier.
The code is free forever under GPL v3. The name LandYacht is trademarked. Both things are true and compatible.
The code is on GitHub. The documentation is plain language. The hardware list is a $20 order. Start with one node, add the rest when you're ready.
