Roamer Gen 1
Roamer's first generation leisure batteries, such as the Roamer 12V 200Ah Xtreme. Sensa reads the battery's own management system over Bluetooth so you can see its charge and cells from the dashboard.
Sensa Connection Method
Bluetooth.
Installation
Install it following Roamer's instructions, within Bluetooth range of a Bluetooth proxy or the Sensa unit.
Configuration
There is no configuration necessary on the battery before adding to Sensa Nomad.
Adding to Sensa Nomad
Close the battery's phone app first, and disconnect anything else using its Bluetooth. The battery's management system allows only one Bluetooth connection at a time, so while another app or device is connected, Sensa cannot reach it.
Open Settings, choose the Devices tab, tick it under Discovered and press Add Selected Devices. If it is not there yet, press Scan.
See Adding devices for more.
What you see
Once the first reading arrives, the battery is named with its capacity, for example Roamer 200Ah Leisure Battery, and appears on the BMS tab of the Habitation dashboard with:
- State of charge
- Voltage, current and power
- Remaining capacity and cycle count
- Each cell's voltage, and the spread between them
- Battery and BMS temperatures
- Whether charging and discharging are allowed
Sensa reads the battery every 30 seconds.
Good to know
- One Bluetooth connection at a time. If the Roamer phone app is connected, Sensa cannot read the battery. Close the app and leave it closed. See Roamer Gen 1 battery readings drop to unavailable.
- No balancing readings. This battery has no active balancer, so balancing figures do not appear.
- It is watched for you. Cold-charging protection, Battery cell imbalance and Battery output turned off all work with it.
