Picture

The EV Charger requires atleast firmware version 1.8.7 to have support of every expose of this external converter. You can check the firmware version by reading the swBuildId attribute in cluster genBasic, endpoint 10 after pairing, by using the Dev console in Zigbee2MQTT.

New firmware and firmware update guide can be found here: https://doc.clickup.com/9004130215/p/h/8cb07x7-30795/12688a97b1dfa55

As of now, the exposes total_active_energy and last_session_energy is not updated automatically as the attributes are not reportable.

The ev_status attribute is an enum which can be any of the following values:

ev_status
Unknown status: #status
Not connected
EV Connected
Ready to charge
Charging
Paused

Where #status is the bit coded integer recieved from the device.

The alarms attribute is an array which can hold any combination of the following values:

alarms
Welded relay(s)
Wrong voltage balance
RDC-DD DC Leakage
RDC-DD AC Leakage
Temperature error
Overvoltage alarm
Overcurrent alarm
Car communication error
Charger processing error
Critical overcurrent alarm

Installation

https://www.zigbee2mqtt.io/guide/configuration/more-config-options.html#external-converters

1. In your zigbee2mqtt data folder, next to the configuration.yaml file, add amina_s.js.
2. Open your Zigbee2MQTT addon Web UI, navigate to settings, then external converters
3. Click the '+' button, and type amina_s.js into the text box which appears.
4. Click submit and restart Zigbee2mqtt

Pairing

When Amina S is powered up it will start looking for networks to join. If it has been associated with a network it will try and find this network.

Amina S will for the first 5 minutes after power on event look for a network to join on all Zigbee channels in the 2.4GHz range intensively, and then gradually look for networks with less and less "eagerness". This means that the highest probability of finding a network will be the first 5 minutes after power on.

You can use the install code to facilitate the joining process.
