Using the Card

Using the Protocol Wizard Card

The included Protocol Wizard Card is your main tool for exploring and configuring devices.

How to Add the Card

1. Edit a dashboard → + Add Card
2. Search for "Protocol Wizard Card"
3. Select your device from the list (device_id from editor)
4. The UI of the card will be specific to the protocol (Modbus/SNMP.etc.) of the device selected for control
5. Done!

Probe and control any register or OID in real-time with the included card

What the Card Does

• Shows current device & protocol (auto-detected from hub). This needs to filled in order to be able to communicate with a device
• Read: Probe any register/OID instantly
• Write: Test values (only on writable registers/OIDs)
• Raw mode: See HEX, ASCII, binary output
• Table view: For SNMP walk — see full OID + value table
• Create entities: Add permanent sensors/numbers/selects from discovered values

Tips

• Use auto for register type when discovering — card detects holding/input/coil/discrete
• For writes → always select holding or coil (auto is read-only safe)
• Long SNMP results → use the multi-line textarea or tranform into a table view
• Favorite OIDs/registers → save them as entities in the integration

The card is live — changes apply instantly, no restarts.
