@v5x/web/solid provides a provider plus signal helpers backed by @v5x/web. 
import {
  V5Provider,
  createV5Connection,
  createV5Snapshot,
} from "@v5x/web/solid";

function DeviceButton() {
  const snapshot = createV5Snapshot();
  const connection = createV5Connection();

  return (
    <button
      onClick={() =>
        snapshot().connected ? connection.disconnect() : connection.connect()
      }
    >
      {snapshot().connected ? "Disconnect" : "Connect"}
    </button>
  );
}

export function App() {
  return (
    <V5Provider>
      <DeviceButton />
    </V5Provider>
  );
}
createV5Snapshot() mirrors the client snapshot into a Solid signal and automatically unsubscribes when its owner is cleaned up.
