SwitchBot Device Help

Does anyone know why, since my phone has gone in for repair, my switchbot curtains and Bots have stopped work, if I go into Switchbot app in Home Assistant devices, and click on the Curtain or Bot driver, it opens but is greyed out, and says unavailable, this is very important to me as I’m disable, and some movements are very painful. I was thinking about use Node Red, as I have a SwitchBot Hub, but can’t get the API Token, as phone is not available.
