 I forgot the password to my old HA instance, so I bought a nice, new, and shiny 128GB Samsung A2 card and used [balenaEtcher](https://www.balena.io/etcher/) to write the balena os to it. I then spent two days finding the right combination to get both [balena-homeassistant](https://github.com/balenalabs-incubator/balena-homeassistant) and [balena-rpiplay](https://github.com/rahul-thakoor/balena-rpiplay) working in tandem.
