What's New in Solar Spotter
1.8.2
June 10, 2026
NEW — Battery Bluetooth (BETA). Pair your battery's built-in monitor over Bluetooth and the app reads your live state-of-charge directly — no more guessing the %. The sundown projection and sunrise check now anchor on a real reading. The app sees what's pushing in (solar, your DC-DC, or both) and what your fridge or other gear is pulling out — so the day's plan stays honest whether you're driving in or parked up. Built for batteries that use a JBD or JK monitor (BMS) — like LiTime, Fogstar, iTechworld, Power Queen, Photonic Universe, KickAss and Supervolt. Confirmed on iTechworld; we're verifying more. If yours doesn't connect, tap "Report a Bluetooth issue" and we'll get on it. This update also sharpens the free Solar Day so it reads the rest of your day — not the hours already gone — and makes Bluetooth reconnect to your battery quietly in the background. Plus the usual under-the-hood polish from real-world field testing.
