I connected a super affordable charging station to Home Assistant to enable Dynamic EV Charging with simple home automations that save me energy and time.
The surprising result is that the home automation I created is incredibly simple yet incredibly useful.
My smart hub (Home Assistant), is aware of my total home power consumption, and based on that and off-peak hours, it can automatically increase or decrease the charging speed of a connected EV. This change has a significant impact, but let me explain how I achieved this and what I used.

Few Words about the Charging Station
I bought the charging station above from AliExpress and I choose this exact brand and model Feyree, because it can integrate locally with my Home Assistant (remember that is my smart home hub).
And also because of the dynamic load balancing feature which actually allows changing of the charging current remotely without the need of disconnecting the EV changing the settings and connect again. And this is super important for maximum saving on time and energy.
The charging station cost me $222 US dollars because I used a $30 discount coupon (see the table above). Here are some other important features about this Charging Station.
- This device can charge any EV with Type2 connector, so yes it can charge your Tesla, Mercedes, Ford, Audi, Renault, Nissan, Hyundai, whatever,
- It supports charging from 6A to 32A on single-phase and there are also 16A and 32A three-phase versions that should work as well.
- It has an IP65 rating which means it can work in any weather conditions
- It comes with a 5m long very nice charging cable,
- some clamps
- And RFID cards that can be used to unlock charging if you mount the Charging Station somewhere on a public place.
Adding this Feyree Charging Station in Home Assistant can be a bit tricky as the Local Tuya custom integration have to be used, and because there are at least 4 different Local Tuya integrations I did the heavy lifting for you. I tested them all and I found the one that is working very well.
