It's a bright LED readout that shows voltage and temperature, cost me about $10 on Aliexpress.
I had one wired to the battery as an extra, fused and switched.

I added an auxiliary battery to my 12V system.
I can monitor my main 12V battery through a device plugged into the lighter socket. I needed a way to monitor the aux battery as well.
I wanted to keep an eye on my auxiliary 12V battery, so I installed this device: Vgate Battery Assistant Tester BLE4.0 Not all that useful, but...
I can only offer my own experience. My 2012 Prius Plug-in had a 4.4 kwh battery that Gave me 20 kms of EV range when it was new. When I sold it...
I don't think that's legal anywhere.
I'm no physicist, but I think it's possible to block UV rays without using dark tints.
I expect that a firmware update may be available as protocols change
I've never heard of a solar panel charge controller that needed an external power source. I'm sure the circuitry incorporates some sort of buck...
I'm using the paid version of Car Scanner, but I'm sure it only shows information for sensors that exist on the car. I'm not sure that every car...
I think you'd have to get pretty far into the technical weeds to find the true answer, but it seems to go against common sense to have the solar...
None of which describes maintaining the charge level of the 12V battery with the solar roof.
I don't see how the solar charging system would need to drain the 12V system. The solar panel likely feeds into the hybrid battery charging...
It's not up to chance how it works.
I haven't found any evidence that the solar roof charges the 12V battery. That means the 12V battery can drop in voltage to a level that disables...
It wouldn't help you if your battery went flat while your car was parked inside. If I didn't know better, I'd say Toyota has contrived to drive...
I wouldn't assume that. I think it's for charging the hybrid battery. But it would be much more useful for that purpose.
But telling you it's worthless is helping you. Anything else is just enabling a bad choice.
