Plan a two-screen solar monitoring setup

Give the two devices different jobs

The Sunstead host reads supported equipment and maintains local history. A satellite screen opens the host’s dashboard in a browser over the local network. The screen displays the information; it does not need to become another collector for the same equipment.

This distinction matters when choosing hardware. A tablet in the kitchen and a display beside the equipment can show the same host. Connecting a second reader to a communications port may create a separate compatibility problem and is not part of adding a browser screen.

Sketch the path before buying hardware

Draw the host near its equipment connection, then the network path to the second screen. Identify whether the screen will use Wi-Fi or Ethernet and whether its location has reliable connectivity. Include its own power supply and mounting needs.

Test viewing before granting administration

Open the local address shown by Sunstead on the second device. Confirm current timestamps and the same equipment identities. Test ordinary viewing first so access and connectivity problems stay separate.

Local administrator pairing is only for a screen that should administer the installation. In Remote & displays, a current administrator can generate a one-use pairing code that expires after five minutes. Do not pair a publicly accessible wall screen as an administrator merely to make the page easier to open.

Plan for screen behavior

Check browser zoom, portrait versus landscape layout, display sleep and the distance from which someone will read the values. Test touch targets with the actual device. A screen that looks impressive at arm’s length may be unreadable across a room.

Decide what should happen after the tablet restarts or the Wi-Fi briefly disappears. Browser startup and kiosk behavior belong to the screen’s operating system; do not assume every tablet can automatically reopen an authenticated session in the same way.

The Raspberry Pi remote-access documentation provides background on local addressing and host discovery. Use the address actually displayed by your installation rather than copying a generic example.

Use a two-screen acceptance check

• Both screens reach the same host and identify the same equipment.
• Reading timestamps advance on both.
• The intended screen remains readable at its normal distance.
• Viewing and administrator permissions match each screen’s role.
• A reconnect is distinguishable from a frozen page.
• The host remains useful when the satellite is turned off.

Record the screen’s bookmark and network name in the handover. If only the satellite stops working later, compare it with the host before changing equipment settings. That comparison is the main diagnostic advantage of having two independent views.
