Wifi Car Battery Monitor With Shelly UNi for Only $12

Wifi Car Battery Monitor With Shelly UNi for Only $12USD

After having a battery tender stop working and ruining a $300 car battery, i went on the hunt for a wifi solution that will notifiy me if there are any problems with the charger, while a car is in storage. I know you can always disconnect a cars battery, but with some models access to the battery is a pain, especially if you want to close doors that will only open with an electronic release. This allows me to leave the cars with a trickle charger and if anything happens, this will send a notification to my phone when the battery voltage drops below a threshold. It also allows me to quickly check the state of charge on a few cars in a couple of seconds. I have been using this on a car for just over a month and shelly infrastructure seems rock solid. Very impressed.

The shelly is a really powerful device and this use is probabaly on its more basic side. But it definitely does what i needed.
