The Enel X JuiceBox 40 v2 EV Charger Main Circuit Board to replace your failed one. The v2 is the one in a plastic case vs the v1 which has a metal case.
Even though JuiceBox sold out to Enel X, who then went out of business and move application support to VoltiE Power Up app, your EV charger will still function in stand alone mode or you can choose to connect it to the VoltiE Power Up app.
VoltiE Power Up app does not support time of day charging so no big advantage over stand alone mode.
