Build a circuit for multiple voltage measurements and publish on website

I have a lot of batteries I have to monitor the voltage on. Rather then check every battery every hour I’d like to automate this. I’d like a circuit to attach to each battery that can read the voltage and send the result to a web page. There will be wi-fi in the area. The sender must be able to transmit 200 meters. To cut costs one possibility is to send the voltage to a receiver (or several receivers) and then send the result to a web page.

I need to measure from 11- 15 volt at steps at 0.1 voltage steps. Every sender must have an ID so I can identify the battery with low voltage. The voltage source for the sender will be the same battery as it’s monitoring. It is important to minimize the current used for the sender so the sender is not responsible for tapping the battery.
