Review on 🔋 Enhanced SchuLink+ Wireless Vehicle Battery Monitor - Displays Battery Charge Percentage by Antonio Rojas

Install this at home before moving to a remote RV. There was an error. The app (which has tried both iPad and Android) randomly says it can't connect and assumes I'm connected to a VPN or otherwise disconnected. You have to re-login almost every time you use the app. Other complaints I could live with if it were at least reliable: No indication of when the battery readings were taken ie if it's disabled - was it 5 minutes ago or 5 hours ago? When unplugged (which it seems to be most of the time) it shows the last charge percentage, i.e. 75%, but doesn't say what voltage. So 75% means 12.4V or 12.0V? We will first try to build a reliable voltage meter using RasPi or esp8266.
