After successfully using WIFI with my Cerbo GX for about a year, I decided to install a Victron GX LTE 4G-E device with SIM card as a backup internet connection for the Cerbo GX. However, whenever there is no active data subscription for the GX LTE 4G-E SIM card, the Cerbo GX fails to use the available WIFI and VRM sends no data alarm even when there is active WIFI internet. VRM starts receiving data only when I load data into the GX LTE 4G-E SIM card again.
How can I achieve my goal of having Cerbo GX use WIFI internet as default and only using the GX LTE 4G-E connection when there is no WIFI internet? Right now, it is partially doing the opposite of this.
