Just tested and this works great on macOS with Plash [1] by Sindre Sorhus. I couldn't find too many URL parameters to control it, but the FAQ does mention an ?obs parameter to hide the interface by default and ?weather=... to choose the weather. This URL in Plash works as described:

    https://loficities.com/tokyo/?obs&weather=leaves

Good to know it works with Plash! Thanks for sharing the setup.
