Tap Electric for Homey
Your EV charger, now part of your smart home.
Bring your Tap Electric–connected charger into Homey and turn it into a fully-fledged smart device. Authorize a session with a single tap, get notified the moment someone holds an RFID to the charger, and let Homey’s smart charging take the wheel: top up on solar surplus, follow dynamic energy prices, or run overnight on a schedule — all without lifting a finger.
Whether you have a Peblar, Alfen, Easee, Wallbox or any other Tap-supported charger, this app makes your EV as natural to automate as the lights, the thermostat or the blinds.
What you get
Charger device
Pair your charger as a Homey EV device — one per connector. The tile shows live charging state, an authorized-session toggle (uses a configurable default RFID), a power slider that integrates with Homey’s smart-charging engine (dynamic prices, solar surplus, schedules), kWh totals, and live wattage. Underneath: standard OCPP `SetChargingProfile` with optional `ChangeConfiguration` fallback per vendor.
1. Install the app and add the API key
Install Tap Electric from the Homey app store, then:
-
Open the app’s settings (mobile app: More → Apps → Tap Electric → *Configure app).
-
In a browser, log in at https://app.tapelectric.app, open Account → API management, click Create API key and copy the value (Tap only shows it once).
-
Paste the key on the API key tab in the app settings and click Save and test. The app verifies the key against Tap and automatically registers a webhook so the token presented trigger fires in realtime.
2. Add your charge cards (RFIDs)
Tap encrypts the token identifiers it returns over its API, so the app cannot discover your physical RFID UIDs on your behalf — add them once, manually:
-
Open the Charge cards tab.
-
Read the UID off the back of your card, or scan it with a USB RFID reader / NFC-enabled phone. Most home users have a 7- or 10-byte hex UID like `04A1B2C3D4E590`.
-
Give it a friendly name (e.g. Husband’s card) and click Add.
These tags now show up in the autocomplete of the Authorize flow card and feed the Default RFID device setting (see step 3).
The “Recent swipes” panel on the same page is informational. Those identifiers are OCPI/encrypted tokens — they are not usable as an OCPP idTag. Use the raw card UID.
3. Pair the charger as a Homey device
In the Homey app, Add device → Tap Electric → Charger. The discovery list shows every connector across every charger your API key sees; multi-select to pair them all in one go. Once paired, open the device settings to set:
-
Phase setup — 1-phase 230 V or 3-phase 230 V. Drives the W ↔ A conversion for the power slider.
-
Default RFID — used by the Session Authorized toggle on the tile. Leave empty to disable start-from-tile; the Authorize flow card still works.
