As more and more people are using HA, it would be good to see an official Home Assistant integration.

I might tweak this slightly. The community maintained HA plugin works fine, it’s limited by the absence of a local API. I want to poll at least every 30 seconds, which likely isn’t scalable in server infrastructure without a subscription.
For the avoidance of doubt, I will not entertain paying for a subscription to access this data.
Matter version 1.3 added EVSEs. Adding standards compliant Matter support to the E2 would add support for every modern home automation system - without the additional cost of per-platform support resources.

Also came to see if there is local home assistant support for EvNex. ( 2025 September).
The big question is, can this data be retrieved over Bluetooth, personally I use a CT clamp to measure the power locally and the api is good enough for controlling the functions.
