Overland Controller
|
||||
# Overland Controller
|
||||
|
||||
A modular ESP32 and Raspberry Pi Pico based monitoring and control system for overland vehicles, campers, trailers, van builds, and mobile power systems.
|
||||
Overland Controller is a local-first vehicle power and monitoring system designed for overland, camping, and off-grid vehicle use.
|
||||
|
||||
The project uses a distributed architecture consisting of:
|
||||
Current target vehicle:
|
||||
|
||||
* An ESP32 controller mounted near the battery and electrical system
|
||||
* A Raspberry Pi Pico 2 W dashboard mounted in the vehicle cabin
|
||||
* Local WiFi communication
|
||||
* Offline-first operation
|
||||
* Expandable sensor and relay support
|
||||
* Open JSON APIs for future integrations

||||
Firmware now uses generic identifiers:
|
||||
|
||||
Relays:
|
||||
|
||||
text id="4xvc8l" relay_1 relay_2
|
||||
|
||||
Temperature sensors:
|
||||
|
||||
text id="xq2e8v" temp_1 temp_2 temp_3 temp_4 temp_5 temp_6 temp_7 temp_8
|
||||
|
||||
Installation-specific names now belong in saved configuration.
|
||||
|
||||
### JSON Status API Improvements
|
||||
|
||||
Reworked status response format.
|
||||
|
||||
Changed from:
|
||||
|
||||
json id="k8l5yx" { "temps": { "outside": 72.0 } }
|
||||
|
||||
To:
|
||||
|
||||
json id="k3g0ey" { "temps": [ { "id": "temp_1", "name": "Outside", "temperature_f": 72.0 } ] }

|
||||
- WebUI is now the preferred initial configuration workflow.
|
||||
- Pico dashboard remains planned as the instant-on physical dashboard.
|
||||
- Built-in ESP32 relays are the current planned relay switching method for Starlink Mini and fridge.
|
||||
- BMS source now reports configured JBD BMS even when disconnected.
|
||||
|
||||
### Fixed
|
||||
|
||||
- Restored default NimBLE connection behavior after custom timeout caused BMS connection failures.

||||
- Trimmed WiFi credentials from setup inputs.
|
||||
- Improved WebUI organization by moving setup/configuration controls to the Config tab.

|
||||
### Known Notes
|
||||
|
||||
- BMS connection can still temporarily block the ESP32 while attempting BLE connection if the BMS is out of range.
|
||||
- WebUI BMS disable/enable controls are intended to make bench testing easier.
|
||||
- DS18B20 multi-probe final install should use a proper terminal/distribution board rather than temporary Wago wiring.

|
||||
See:
|
||||
Current rear enclosure target:
|
||||
|
||||
docs/api.md
|
||||
- ESP32 relay board
|
||||
- Compact fuse block
|
||||
- Ground bus
|
||||
- CAT6 keystone
|
||||
- DS18B20 terminal/distribution board
|
||||
- Built-in relay outputs for Starlink Mini and fridge

|
||||
Relay strategy:
|
||||
|
||||
## UART Status
|
||||
Battery positive -> fuse -> relay COM -> relay NO -> load positive
|
||||
Load negative -> ground bus
|
||||
|
||||
Partially complete.
|
||||
The built-in relays are currently planned for:
|
||||
|
||||
Current UART capabilities:
|
||||
- Starlink Mini
|
||||
- 12V fridge
|
||||
|
||||
- Status requests
|
||||
- Dashboard communications
|
||||
- Basic command support
|
||||
External automotive relays remain a future option for higher-current loads.
|
||||
|
||||
Missing goal:
|
||||
## Temperature Sensor Direction
|
||||
|
||||
UART should eventually expose every operation available through HTTP and serial.
|
||||
DS18B20 bus:
|
||||
|
||||
Target:
|
||||
ESP32 GPIO4 = data
|
||||
ESP32 3.3V = VCC
|
||||
ESP32 GND = ground
|
||||
|
||||
UART becomes the primary dashboard integration interface.
|
||||
Required:
|
||||
|
||||
---
|
||||
One 4.7k pull-up resistor between data and 3.3V
|
||||
|
||||
## Simulator Status
|
||||
Final install should use a terminal/distribution board.
|
||||
|
||||
Working.
|
||||
|
||||
Simulator provides:
|
||||
|
||||
- Fake ESP32 controller
|
||||
- Fake Pico dashboard
|
||||
- Test data generation
|
||||
- Protocol validation
|
||||

|
||||
|
||||

|
||||
- Generic hardware model
|
||||
- Generic API model
|
||||

|
||||
|
||||
- Overland vehicles
|
||||
- Campers
|
||||
- Trailers
|
||||
- RV electrical systems
|
||||
- Mobile command systems
|
||||

|
||||
HTTP API
|
||||
Lightweight embedded web dashboard
|
||||
WiFi AP recovery network
|
||||
|
||||
Pico 2 W:
|
||||
|
||||
Instant-on physical dashboard
|
||||
UART client
|
||||
Touchscreen UI
|
||||
Local control surface
|
||||
|
||||
Optional future Pi Zero 2 W:
|
||||
|
||||
Advanced web app
|
||||
Historical logging
|
||||
Graphs
|
||||
MQTT/Home Assistant bridge
|
||||
Advanced integrations
|
||||
|
||||
The base system should remain ESP32 + Pico.
|
||||
|
||||
A Pi Zero may be added later as an optional expansion module, not a required component.

Current:
|
||||
|
||||
ESP32 AP mode
|
||||
http://192.168.4.1
|
||||
- AP always available
|
||||
- STA attempts saved networks by priority
|
||||
- AP remains available even when STA is connected
|
||||
|
||||
Planned:
|
||||
Examples:
|
||||
|
||||
ESP32 AP + STA mode
|
||||
Priority 1: Starlink
|
||||
Priority 2: Home WiFi
|
||||
|
||||
Expected future behavior:
|
||||
## Next Recommended Work
|
||||
|
||||
AP always remains enabled
|
||||
ESP32 attempts to join configured WiFi networks
|
||||
Multiple saved networks are tried in priority order
|
||||
|
||||
Example network priority:
|
||||
|
||||
1. Starlink
|
||||
2. Home WiFi
|
||||
3. Shop WiFi
|
||||
|
||||
This allows:
|
||||
|
||||
- Direct connection when camping without Starlink
|
||||
- Phone access over Starlink at camp
|
||||
- Phone/laptop access over home WiFi in the driveway
|
||||
- Recovery access even when STA setup fails

## Recent Design Decisions
|
||||
|
||||
The onboard ESP32 relays may be acceptable for low-current loads such as:
|
||||
|
||||
Starlink Mini
|
||||
12V fridge
|
||||
small accessories
|
||||
|
||||
Reason:
|
||||
|
||||
- Starlink Mini current draw is modest
|
||||
- Typical 12V fridge current is modest
|
||||
- Smaller enclosure is a priority
|
||||
|
||||
External automotive relays remain recommended for higher-current loads or future expansion.
|
||||
|
||||
The current enclosure concept includes:
|
||||
|
||||
- ESP32 relay board
|
||||
- Small fuse block
|
||||
- Ground bus
|
||||
- CAT6 keystone
|
||||
- CAT5/CAT6 run to dash
|
||||
- 12V feed to dash
|
||||
- Buck converter in dash enclosure
|
||||
|
||||
The dash power plan is:
|
||||
|
||||
Rear fused 12V
|
||||
-> CAT5/CAT6 blue pair
|
||||
-> dash buck converter
|
||||
-> Pico VSYS
|
||||
1. Verify WebUI setup workflow after fresh flash.
|
||||
2. Clean up DS18B20 physical distribution hardware.
|
||||
3. Test 2-4 temperature probes after distribution board is installed.
|
||||
4. Start Pico dashboard MVP over UART.
|
||||
5. Add config backup/restore.
|
||||
6. Improve BMS out-of-range behavior without changing NimBLE connect timeout.

## Current Relay Switching Decision
|
||||
|
||||
For the current Starlink Mini and fridge use case, the built-in ESP32 relay board relays are the planned switching method.

Use positive-side switching:

## DS18B20 Final Install Direction
|

Temporary Wago wiring proved one probe, but final install should use a proper terminal/distribution board.
