Introduction

The Sensa Control System supports many devices, most of which install the way the manufacturer describes. We only cover devices here that have a Sensa-specific install step.

Discovery

During the installation of the Nomad/Helm integration, the discovery phase will identify as many primary devices as possible. Often further configuration will be required in later stages of the installation, but our goal is to find as many as possible. If all your devices are not yet installed, you can always run a Reconfigure at any time to add/remove device changes.

Advanced

Our discovery will perform the following types of scanning:

• ESPHome HTTP probe — sweeps the configured subnet over HTTP (port 80 by default), filters by the ss- hostname prefix, fetches the root page, then reads the ESPHome SSE event stream to pull out device type, model, MAC and firmware version.

• DHCP cache lookup — queries Home Assistant's built-in DHCP watcher and matches MAC OUI prefixes to identify non-ESPHome devices like the Teltonika router.

• Static IP probe — TCP connects to well-known address/port pairs for devices that sit on their own subnet and won't show in DHCP (e.g. Starlink dish at 192.168.100.1:9200 via gRPC).

No mDNS/Zeroconf or SSDP sniffing — those are handled by HA's own discovery integrations, and we actively suppress the native ones for devices we already own (Teltonika, Starlink) to avoid duplicates.
