We've updated the ZAP firmware to support more than just P1 meters. The latest version now also works with inverters and EV chargers, see Compatible Devices.
Firmware | Purchase date | Capabilities |
1.2.1 | Before November 28 | ✅ P1 meters ❌ Inverters |
1.6.20+ | November 28 and later | ✅ P1 meters |
If you bought your ZAP before November 28, 2025 and want to connect a compatible inverter or EV charger, contact us at [email protected].
If you only use the ZAP as a P1 meter reader, no update needed — your ZAP will continue working just fine.
If you bought your ZAP on or after November 28, 2025, you're already on the latest firmware — no action needed.
