I'm looking for the cheapest possible 4g router / data only sim card combination possible but I need to figure out how much data I will require to use solar Assistant, pv pro, and whatever updates the solark may decide to pull. It's an off grid property about an hour away. I can probably do the updates from my phone hotspot when I'm there if I can opt to not have them download automatically and can easily switch networks when I'm ready to update. I'm assuming just monitoring data will be a pretty small amount. I might eventually add a security camera later but for the sake of this experiment I want to keep expansion creep to a minimum.
