Smart EVSE via MQTT

Smart EVSE via MQTT ================== Bring your Smart EVSE-3 into Homey as a fully featured EV charger. This app connects to your MQTT broker, subscribes to the topics your Smart EVSE already publishes, and turns them into a rich Homey device you can view, control and automate - no cloud, no polling, no extra hardware. Everything stays on your local network: Homey talks to the broker, the broker talks to the Smart EVSE. You bring your own MQTT server (Mosquitto, the one built into Home Assistant, an add-on on your NAS - anything works). What you get ------------ - Native Homey EV charger: start and stop charging, set the target power, and flip between the Smart EVSE Normal, Smart, Solar, Pause and Off modes straight from the device tile. - Live measurements for charge power, energy charged this session, total energy charged, mains and EV currents per phase, mains import/export, and home battery current. - Charging state that actually reflects reality: "Charging", "Connected", "Charging Stopped" and friends, so the built-in "Started/Stopped charging" flow cards fire at the right moment. - RFID support: a flow trigger when a card is swiped and an action to simulate a swipe from a flow. - LED colour configuration for each mode (Off, Normal, Smart, Solar, Custom). - Live availability via MQTT LWT: the device turns unavailable the moment the Smart EVSE drops off the network, and comes back automatically. - Diagnostics at a glance: Wi-Fi SSID/BSSID/RSSI, ESP temperature, uptime, OCPP status and load balancing role. Setup ----- 1. In the Smart EVSE web UI, enable MQTT and point it at your broker. Note the topic prefix it uses (for example Smart EVSE/1234). 2. In Homey: Settings -> Apps -> Smart EVSE via MQTT -> Configure and enter your broker details (host, port, protocol, optional username/password). 3. Add Device -> Smart EVSE and fill in the same topic prefix. Homey will start receiving values immediately. Works with any Smart EVSE-3 firmware that has MQTT enabled.
