Relays
Relays provide the Switching capability within Sensa Nomad. Currently we support the following:
Waveshare ESP32-S3-ETH-8DI-8RO
This model and the -C variant are our recommended relays. They offer physical switch connectivity for those rare emergencies where your Sensa Nomad system is not running. The main difference between this model and the -C variant is the RS485 connectivity.
Waveshare ESP32-S3-ETH-8DI-8RO-C
This model and the non -C variant are our recommended relays. They offer physical switch connectivity for those rare emergencies where your Sensa Nomad system is not running. The main difference between this model and the non -C variant is the CAN connectivity. This model is useful if connecting to a CAN bus, maybe a Roamer or Fogstar battery, both of which support both Bluetooth and CAN bus connection for BMS monitoring.
Shelly Pro 4PM V1
A four-circuit mains relay for a DIN rail, which also measures the power each circuit is using. On the Switches tab each circuit is a tile showing its live draw in watts, and Sensa raises an alarm if a circuit overheats or overloads.
Shelly Pro 4PM V2
The newer hardware version of the Pro 4PM. Sensa adds and shows it exactly as the V1.
Shelly 1 Gen4
A single-circuit relay that switches one circuit on and off, without measuring power.
Shelly 1 Mini Gen4
A compact single-circuit relay that switches one circuit on and off, without measuring power.
Shelly 1PM Gen4
A single-circuit relay that also measures the power the circuit is using.
Shelly 1PM Mini Gen3
A compact single-circuit relay that also measures the power the circuit is using.
Shelly 1PM Mini Gen4
A compact single-circuit relay that also measures the power the circuit is using.
Every Shelly needs its device password turned off and a fixed address on your router before you add it. See each model's page.
