Feyree WIFI smart EV charger

Thanks Eduardo, i’ll try it…

Hi all, somehow I can’t find the information I need to setup local tuna. Where can I find Client ID, Secret, User ID and username in Tuya Smart app?

I have my freyee charger working in Tuya Smart app.

Hey Eduardo,
I’m looking to have a setup similar to yours. The charger you mention has the ct clamp and the 2 wires for dynamic load balancing. You can just ignore those and use a shelly EM instead?

45

Yes, forget about the dynamic load balancing from the charger as it’s pretty basic. I installed one for a friend (he doesn’t run HA) and it’s just “good enough”. Just use the Shelly EM with the automation and it’s much more powerful.

Great news then. Feyree has a lot of diferent models, I’m looking to buy this one
Do you know if there are significant differences between them regarding the API they use or it is mostly cosmetic changes?

47

That’s very similar to the wallbox I tested, the only difference I see is the bigger screen so I guess it’s a newer version. As far as software it should be similar, the only thing I can’t confirm is if it’s correctly identified by Tuya Local integration.

Hi, just seen this post and thinking about getting one of these chargers as my current charger has to stop the charge to adjust amps and I’d like some real-time charging metrics.

How are you doing with the charger a few months down the line?
Any issues?
Is the start/stop command still not working ?

I’m going to be using it mostly with an Intelligent EV charging tariff but have found my car doesn’t always get the stop commands (as my car doesn’t connect to WiFi and the signal isn’t great around here) so the start/stop would be great as a kill-switch if my car doesn’t stop charging after my electric price goes back up

Hi, I was thinking, since there is a lower limit on most wallboxes of 6A of current (which in a 3 phase 230V means around 4kW of power) and some wallboxes can operate both in single and three phase mode… Why don’t we add another thing to the automation with 2 2-pole contactors (say KA1 for L1 + N and KA2 for L2 + L3 - some wallboxes have them built in, saw Tera ones with this built in, but even externals would work), when the available power is less than 5kW it would:

  • stop the charge on the car and verify it stopped (if car is integrated)
  • stop the charge in the wallbox and verify it stopped
  • set the available power to the minimum possible (or 6A) for safety
  • turn both KA1 and KA2 off
  • turn only KA1 on
  • set the appropriate charging current (for single phase) for the available power
  • start charge for wallbox
  • start charge for car (if available)

As soon as 6-7kW or so of power is available again, then the reverse would happen.

I can try seeing if I can implement this in your automation, but I need someone’s help to test it.

What do you think?

51

I can confirm it works but I almost never use it in 3 phases mode. With one phase I can follow the solar power way more precisely and sooner in the morning as it only needs 1350w of sola power to match the power at 6A.
But be carefull, it’s probably not gonna go well if you turn phase 2 and 3 when phase 1 is running

Check my blueprint. The charger doesn’t need to stop, just apply a delay when scaling down the amps. That’s considered already in the automation and it’s working fine with the Feyree

53

Yes, that’s why for the 1 to 3 phase switch and back I’d stop the charge completely. I’ll try, thanks!

I’m also trying another brand of charger (dé depow) as it’s certified in my country instead of the feyree but still has tuta support.

I have the same charger with dynamic load balancing capability.

Integration with localtuya works great, but there doesn’t seem to be any option to set max load balancing current, only max charging current.

For example; you might have a 3x20A home fuse installation, so you’d want to limit your charger to 16-18A (so a bit of safety margin). Now without solar, you set this value once and forget it.

But if you wanted to use excess solar + grid power to charge your car as quickly as possible, you’d want that safety limit raised acording to solar production.

So for example, you have 10kW solar production + 13.8kW available from the grid and 2kW overall consumption, you then have a new limit of 21.8kW available to charge, so about 31A.

So, is it possible to implement setting dynamic charge current as well?

Can anyone confirm that this 6 A “hack” still works?
I’m looking for a portable 11 kW charger with Home Assistant “support” and 6 A. The Feyree charger sounds good, but the official data sheet says 8 A as the minimum charging current.
Also the tuya local device yaml contains the minimum value of 8 A:

range:
    min: 8

Also past releases had this value. I don’t know how you got 6 A :thinking: Maybe I’m looking at the wrong part of the code

HomeAssistant can take it to 6A, but not in Tuya app

Regarding the hidden 6 A:
I checked the Tuya data points and there is one for the display of the current. So the charger sends the correct 6 A, but on a different DP.
Created a pull request for this. The author of tuya-local added the DP as an attribute:

Should make things easier :slight_smile:

(cannot edit my previous post) this is the right configuration file for the feyree 3 phase charger:

Hy Markus, i’am exactly at the same point as you where here. Have you managed to come over it? Does you find the way to use the charger with entities in Home Assistant? Thanks.

não consegui configurar este carregador, consegue me ajudar ?
Ele apenas aparece como dispositivo desconhecido no tuya oficial e no local tuya ele não reconhece nenhuma entidade.
