WIFI signal is very weak. The signal doesn't even penetrate a plastic battery box. However, I can see the Victron Battery Monitor 20 feet away. Ordered a stronger block (blue) with the same results. My house battery is less than 10 feet away, but neither device has a strong enough signal. Moved the sensor 7 feet to the starter battery and got the same results. The sensor connects to the solar charge if I leave the sensor on the starter battery box (plastic) and leave the engine bay hatch open. This renders the battery temperature sensor unusable. I like other Victron products but the battery sensors are not up to date.
