I will be buying a RV for travel soon and I will be using HA to control everything I can. But for now I have not purchased any hardware needed for the rv. With that said I would like to get HA all set up so that I only need to add the hardware in the rv and connect it to HA. Is there a way to virtually run HA and use virtual sensors and what not to make sure it all would work before actually buying and installing all the hardware? Thanks for the help in advance.
