Custom Sensors on Astrion
Learn how to display custom sensors and binary sensors on your Astrion Remote using RosCard — practical patterns, workarounds, and step‑by‑step examples.
Can RosCard display custom sensors or binary sensors on Astrion?
Yes — but not as a dedicated "sensor card," and not automatically for every sensor type. RosCard's official card set is focused on control (lights, climate, covers, media, scenes), not generic read‑only display.
How sensors can appear on Astrion today
-
Switch / Light / Cover cards can be bound to any entity that
supports
turn_on/turn_off, includingswitch.my_custom_switchorinput_boolean.virtual_sensor - Scene cards can trigger scripts or automations that react to sensor values, effectively turning sensor state into actions on the remote
- Weather and Media cards already show dynamic, real‑time data (temperature, playback state) — demonstrating that RosCard can render multi‑state data
Practical pattern for custom sensors
Common Pattern:
- Keep your custom/binary sensors in HA as usual
- Create automations/scripts that react to those sensors
- Bind RosCard scene/switch/light cards to those scripts/helpers
- Use the RosCard cards on Astrion to see derived state and trigger actions
Example scenario: Hallway Motion Sensor
- HA has
binary_sensor.hallway_motion - Create an
input_boolean.hallway_occupiedhelper - Automation: motion detected → turn helper ON; no motion for 2 min → turn helper OFF
- Bind a RosCard Switch card to
input_boolean.hallway_occupied - Astrion shows the state and can trigger actions based on it
Limitations
- There is no officially documented "Sensor" or "Binary Sensor" card type in the current RosCard card list
- RosCard cards are primarily designed for control actions, not just passive read‑only displays
- For richer, read‑only dashboards of many sensors, users typically rely on standard Lovelace in HA and view those on Astrion via WebView or other rendering paths, rather than pure RosCard
Workaround: Using WebView
If you need to display a large number of sensors or complex dashboards, you can create a standard Lovelace dashboard in Home Assistant with all your sensor cards, then access it on Astrion via the WebView feature. This is not "RosCard-only" but provides a practical way to view rich sensor data on the remote.
💡 Best Practice: Use RosCard's control‑oriented cards (Switch, Light, Scene) to represent sensor-derived states where you need both visibility and action. For passive monitoring of many sensors, consider using WebView with a standard HA dashboard.
