After months of tinkering and late-night brainstorming, I’m thrilled to share my latest project: integrating a variety of smart devices into my camper van. The goal was to create a seamless, automated experience while on the road, and I’m excited to walk through some of the key components and lessons learned.
Home Location and Weather Tracking
One of the first challenges was accurately tracking the camper’s location and weather conditions. I utilized a Verizon MiFi hotspot with built-in GPS to pull NMEA data streams. By setting up a shell script, I can update Home Assistant’s current location every 30 minutes when the camper is away from home. This integration has been incredibly reliable and provides accurate weather data wherever we go.
Propane Tank Monitoring
Safety is paramount, especially with propane usage. I opted for Mopeka propane tank gauges, which are renowned for their accuracy. These sensors provide real-time updates on propane levels, which are crucial for ensuring we never run out while on the road.
Battery Monitoring
Power management is another critical aspect of camper life. I set up a PZEM-017 energy monitor to track battery usage. While it currently doesn’t distinguish between charging and discharging, it’s been a reliable tool for monitoring overall consumption. I’m planning to upgrade this system soon to include direction detection.
Awning Automation
The awning control system has been a favorite feature. Using a Zooz Zen53 motorized switch and tilt sensor, I ensured that the awning can only be operated when the stairs are down and someone is present. This adds an extra layer of safety and convenience.
Lighting and Switches
I replaced traditional toggle switches with momentary switches for a cleaner look and better control. By integrating these with Shelly devices and Tasmota firmware, I’ve been able to create custom tap actions for lighting and fans. It’s been amazing to see how these small changes have significantly improved usability.
HVAC Control
Combining a Z-Wave thermostat with a line-voltage AC unit has been a game-changer. Using an Aeotec heavy-duty switch and a Xiaomi e-ink sensor, I’ve created a unified system that allows me to control both heating and cooling from a single interface within Home Assistant.
Network Connectivity
Maintaining a stable network connection while traveling was a priority. By setting up a powerline connection from the house and using a USB-powered network switch with the MiFi hotspot, I’ve achieved consistent connectivity. A custom Tasmota script ensures the network switches seamlessly between home and cellular connections.
Voice Control and Automation
A HomePod Mini has been the cornerstone of voice control, providing seamless integration with Apple’s ecosystem. Pushing automations to our iPhones via Twilio has added another layer of convenience, such as automatically opening Apple Maps to the camper’s location with a simple voice command.
Challenges and Future Plans
While the project has been a success, there are areas for improvement. Replacing the PZEM-017 with a more advanced battery monitor and tasmotizing remaining Shelly devices are high on my list. I’m also looking forward to enhancing the camper’s dashboards for better visualizations.
This project has been a labor of love, filled with both triumphs and learning moments. It’s incredible to see how technology can transform something as simple as a camper van into a smart, connected home on wheels. If anyone has questions or suggestions, I’d love to hear from you!
