- 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.

I was expecting to see one of those BT battery voltage monitors... Clever solution!
Yeah, I know a few people that tried Bluetooth. But if something goes wrong. You don’t get a warning. This should be handy for anything that’s near wifi. Could set it to warn if a car needs to go on charge for example. I’ll buy a few more I think and put them in every car.
👍
Are you concerned with the power draw on the battery from the Uni?
Not really. The unit is so small, it won’t draw anywhere near as much as the frm or cas.
I did look up current draw a few months ago and a lot of people run them on very small batteries and small solar panels for gate controllers and it’s very minimal.
