Equipment boasting a power handling capacity surpassing 2000 watts
In the world of remote monitoring and smart home automation, the Shelly Plus Uni module has emerged as a powerful and versatile tool for managing low-voltage systems, particularly for boat, van, and camper batteries.
The Shelly Plus Uni is a compact, affordable, and feature-rich WiFi-enabled device designed to deliver precise voltage measurement in two ranges (0-15 VDC and 0-30 VDC), making it perfect for monitoring battery voltage levels in various vehicle and boat installations [1].
To build a WiFi battery monitor using the Shelly Plus Uni, start by connecting appropriate sensors and inputs. This device works with various analog sensors for voltage and current measurement and also supports pulse counting to monitor energy usage or charging cycles [1]. You can use shunts or voltage dividers to safely scale the battery voltage signals into the Shelly's input range.
Once connected to your local network, the Shelly Plus Uni can relay battery data remotely, allowing you to check real-time battery voltage and state of charge via the Shelly app or integrate with home automation platforms [1]. By combining voltage data with pulse or current sensing, you can monitor how your batteries are being charged and discharged, helping you optimize battery use and extend battery life [2].
The Shelly Plus Uni also boasts a custom scripting feature, allowing you to set up custom alarms, thresholds, or data logging routines to trigger notifications or automate other smart home/boat/van functions based on battery status [1]. This feature enables you to set notifications if battery voltage drops below safe levels or exceeds specified thresholds, preventing deep discharge or overcharge remotely [2].
The Shelly Plus Uni can also integrate with other Shelly devices or smart home systems for advanced automation, such as turning off non-essential power loads automatically when the battery is low to preserve power [3]. Its robust design and flexible sensor interfaces make it broadly applicable for battery management in various vehicle and boat installations [1][3].
While a new all-in-one WiFi meter has been discovered, it has not been tested by the author of this article [4]. It is designed for 12V and 24V batteries and provides mobile alerts for any issues, but its specific measurements or monitoring functions are not specified [4].
To build the battery monitor, you will need the Shelly UNI, the Shelly Smart app, a temperature sensor, and cardboard for assembly [5]. A temperature sensor can be easily added to the WiFi battery monitor project and can be purchased from AliExpress or Amazon [5]. The Shelly UNI device also has multiple applications for converting equipment on a boat into smart devices and controlling them remotely [6]. Additionally, it can be used to build additional alarms and inventions [6].
In conclusion, the Shelly Plus Uni is an ideal solution for building a remote battery monitoring system for boats, vans, or campers. Its precise voltage measurement, WiFi connectivity, and custom scripting capabilities enable comprehensive battery management and automation remotely [1][3]. For those interested, a video demonstrates how to build a WiFi battery monitor using the Shelly UNI for less than 20 euros [7].

The Shelly Plus Uni can transform various gadgets and systems into smart home devices, extending its functionality beyond battery management [6]. This versatile technology makes it suitable for monitoring and controlling different low-voltage systems, not just vehicle and boat batteries [1]. With its custom scripting feature, it can be programmed to alert users if smart-home-devices exceed safe voltage levels or drop below desired thresholds [1].
