Hi,
now I charge my PHEV with a fixed 10A charger with a dedicated plug that can support up to 16A.
I would like to change it to an EV charger that supports up to 16V and be able to integrate in HA so that I can module the load based on my solar production.
Does anyone know anything like that? And simple to integrate in HA.
Thanks
Marco
I recently bought a Technivolt 101 as it was very cheap.
But i miss interpreted the info i found on internet; it did not come with the mod interface i was hoping for; it required a MID power meter to interface with.
So i ended up adding an esp32 module, faking a MID meter, allowing me to manipulate the data as i see fit 
As result i charge my car only when my dynamic energy prices are negatif, or when i have solar surplus 
Hi,
You've not mentioned voltage, Type 1 or Type 2, but I've seem projects where a simple relay module is used to disconnect the pilot signal to the EV from the EVSE. Connect - charging, disconnect - not. The advantage here is the data signal is switched, not the charging current.
Another option for 240V 16A, is a Shelly 25A relay. Many devices may SAY they can handle high current, but can't. I've not (yet) tested the 25A relay with a 10A EVSE, but that's Monday's job to install for a Type 1 EVSE:
In the UK, the standard socket spec has been changed as sockets rated nominally 13A, can't handle CONTINUOUS 13A without excessive resistive heating (you sound like you have an IEC 60309). BS1363-2 or BS1363/EV are a new type specifically designed for continuous high-current use. If sockets can't carry the rated load for long periods, you can guess how well many switching devices work!
You can see the issue throughout automated kit - big socket, cheap relay, gets hot, risks fire.
Be careful out there!
Thank you for your answers, but I was looking more of an out-of-the-box solution and not DIY, because we are talking about potentially dangerous stuff.
I was thinking about a Type 2 EV Charger (max 3.7Kw 16A) that has an easy integration with HA.
On Amazon there are tons of them but I don't know if some can integrate easily to HA.
In the UK chargers after 2019 need to support a communications standard like OCSP (Open Smart Charging Protocol) by law. This is a widely used standard, but it may be better used pointing the EVSE at your energy provider directly so the provider can control charging when it is cheap.
The catch is that some cars don't just accept charging when the EVSE turns on. A friend has a new leased EV which is supposed to connect to the energy provider for charging control, but the car software is very broken. It is leased from their energy company, which gives a huge fail!
Some EVSE have cloud controls / phone apps that demand login details for the car, so they can control both the EVSE and the EV itself (also adds pre-conditioning and battery level). Yes, that does indeed sound like a huge hack, and a security mess to me! 
In the UK, a typical Type 2 would be 7.5kW (32A, 240VAC). 3.7kW 16A may suggest you are in Europe (231VAC). My experience is based on UK standards.
Basically, see what brands your local market sells and search this forum for an integration and others' experience.
BTW - After fitting a Ogemray SW40 to a 10A EVSE yesterday, all is working, tested, and my friend doesn't need to get up in the night to get cheap energy as the Shelly handles scheduling itself. I did check and test all terminals twice.
You might want to read this thread:
Where (geographically) do you intend to use charger? What's available and what works on your electrical system will depend on that, so if you mention your general location then someone with advice specific to your situation may have a better answer. E.g., I could tell you what I bought in the US, but that might not be at all helpful for you if you're on a different grid.
