XIAO 7.5" ePaper Panel - Home Assistant Dashboard

Sorry for the newb question, but I just got my TRMNL OG kit. I was able to use the guide on the Wiki and I can get the HA dashboard to work while I am at home. Does anyone know how I can get it to work if I want put this at my desk at work (different network than my house)? I’m looking to use a dashboard to have weather/forecast, time/date, state of some sensors that I can monitor while I am at work. TIA.
