It appears that Grizzl-E has streamlined the connection process considerably since we first tried using this unit, and we were eventually able to get our unit a firmware update and get it connected to the ChargeLab app.

Initially, Grizzl-E said its unit could work with either AmpUp or ChargeLab apps, but now it's only the latter. Unfortunately, it took months to get ours to connect. The promise of the Grizzl-E Smart is that it can theoretically pair with any EV charging app that uses the OCPP (Open Charge Point Protocol) 1.6 and, at $539, it's one of the cheapest smart units. Finicky app integration, thickest cable is the hardest to manipulate, changing output or Wi-Fi connection requires removing the faceplate.In no particular order, here are the best of the rest: Tesla Wall Connector EV Charger The ChargePoint app has the most nuanced cost tracking, allowing us to select from among dozens of possible rate plans from our local utility to pinpoint the actual cost down to the penny. It also gives the ability to set charging times to take advantage of variable-cost electricity during off-peak hours (most EVs also allow this to be configured in their settings menu). You can see charge-rate graphs and the charge time and total energy output during each charge. But ChargePoint's vehicle database isn't as comprehensive or up-to-date as the one from Juice Box.

Through the app, you can add your vehicle then the app tailors the percentage of the battery replenished and number of EPA miles added to your specific vehicle. Its Home Flex unit tested here integrates into the same app used to connect to the company's public units.
