Long thread here to get you started:
2.4 GHz routers should yield 150' indoor range and up to 300' outdoor range so extender not required.
It all depends on what type of walls or doors you have. I have a 2.4 Ghz router and I can't get internet in my garage and In-law apartment. My interior doors are solid wood and the wall from the house to the garage is block and there is also an internal block wall to get to the in-law apartment. The garage is about 50 ft. From the router and the in-law apartment 100 feet away. I have a range extender to have internet at the in-law apartment..
I personally have a regular EVSE without WIFI.. Bluelink provides all the info I need.
The Zencar has gone on to a new life at my girlfriend's house where I don't need the lifetime stats.
That's a good reason for it then..I wondered the same thing at first when I got my Zencar EVSE which did a great job with my Kona. But, over a few months, I realized that I wanted an easier way to track my monthly EV charging kWh so I could accurately account for my house electricity vs EV charging. The Zencar's fatal flaw was that its kWh counter would reset after a power outage which made it unhelpful for my purposes. So, then I bought a JuiceBox which has a lifetime kWh counter that I can take measurements from on the 1st of every month (irregardless of whether the power went out or not). We all have our different reasons.
