Smart Switching via WiFi – Up to 63A ⚡ The EARU Electric EAKCB-TM is a compact, smart DIN-rail switch that remotely controls loads up to 63A via your existing Wi-Fi network. From electric boilers and charging stations to air conditioning units and heavy-duty heating systems, switch, monitor, and secure them directly from the Tuya Smart or Smart Life apps , or via voice control with Amazon Alexa and Google Assistant. In addition to switching, the EAKCB-TM offers comprehensive real-time energy measurement : current, voltage, power, and kWh consumption are continuously visible in the app. Five adjustable safety thresholds automatically protect your system in the event of overcurrent, overvoltage, undervoltage, overload, and overheating. 💡 Compare it to the MOES A5? The EARU EAKCB-TM works over Wi-Fi (Tuya) and doesn't require a Zigbee coordinator. The MOES A5 works over Zigbee and fully integrates locally with Home Assistant via Zigbee2MQTT. Choose Wi-Fi for easy app control without a hub; choose Zigbee for maximum local control. ✅ Key Features & Benefits 63A suitable – Switches heavy loads such as boilers, charging stations, air conditioners and electric heaters Real-time energy measurement – Continuous insight into current (A), voltage (V), power (W) and total consumption (kWh) 5 adjustable protection thresholds – Automatic shutdown for overcurrent, overvoltage, undervoltage, overload and overheating WiFi 2.4GHz (Tuya) – No additional hub or coordinator needed; works directly through your home network Timer & Schedules – Adjustable on/off times, countdown timers, and repeating schedules Voice Control – Fully compatible with Amazon Alexa and Google Assistant Power failure memory – Remembers the last setting after power recovery (adjustable) 1P+N design – Switches only the phase wire (L); neutral wire runs continuously CE certified – Approved for use in Europe DIN Rail Mounting – Fits standard 35mm DIN rail 100,000+ switching cycles – Long mechanical lifespan Local physical switch – Manually operable without app or internet 🔌 Compatibility Platform Support Tuya Smart / Smart Life ✅ Fully supported (native) Amazon Alexa ✅ Via Tuya integration Google Home / Assistant ✅ Via Tuya integration Home Assistant ⚠️ Via LocalTuya integration (not native) Apple HomeKit ❌ Not supported Homey / Homey Pro ⚠️ Via Tuya cloud connection ⚠️ Home Assistant users: The EAKCB-TM works via the LocalTuya integration and requires some technical configuration. Want a completely local, cloud-free solution? Then consider the MOES A5 (Zigbee) . 🏠 Practical Example: Smart Charging Station Control The EAKCB-TM is installed on the charging station group in the meter cupboard. In the Tuya Smart app, you can set a daily schedule: turn on at 11 PM, turn off at 7 AM. A current limit of 32A is set – automatic shutdown if exceeded. Monitor your exact charging consumption per session and month via the energy dashboard in the app. In case of abnormal temperature, the device switches off automatically and you will receive a notification on your smartphone. 🔧 Adjustable Security Thresholds Security Adjustable range Action in case of exceedance Flood 1A – 63A Auto power off Overload (power) 1 kW – 26 kW Auto power off Overvoltage 220V – 265V Auto power off Undervoltage 76V – 240V Auto power off Overheating 40°C – 150°C Auto power off 🔄 EARU EAKCB-TM vs. MOES A5 – WiFi or Zigbee? Characteristic EARU EAKCB-TM (WiFi) MOES A5 (Zigbee) Protocol WiFi 2.4GHz (Tuya) Zigbee 3.0 Hub required ❌ No ✅ Zigbee coordinator Current capacity Up to 63A Up to 63A Energy measurement ✅ kWh, V, A, W ✅ kWh, V, A, W Home Assistant ⚠️ Via LocalTuya ✅ Native Zigbee2MQTT/ZHA Local/Cloud-Free ⚠️ LocalTuya configuration required ✅ Completely local Voice control ✅ Alexa & Google direct ✅ Via Zigbee hub Network repeater ❌ No ✅ Zigbee router Ideal for Simple WiFi setup without a hub Maximum local control with Home Assistant ⚙️ Technical Specifications Specification Value Model EAKCB-TM Brand EARU Electric Protocol WiFi 2.4GHz (b/g/n) – 5GHz not supported App Tuya Smart / Smart Life Poles 1P+N Current capacity 1 – 63A Nominal voltage 220V AC Working voltage AC 90 – 280V, 50/60Hz Switching capacity 6 kA Assembly DIN rail 35mm Dimensions 81 x 19 x 67 mm Certification CE Working temperature -20°C to +70°C Mechanical lifespan 100,000+ switching cycles Power failure memory ✅ Yes (adjustable) Short-circuit protection ❌ No (use separate security machine) ⚠️ Points of attention No short-circuit protection – Always combine with a traditional fuse or circuit breaker for short-circuit protection Phase wire only (L) – The neutral wire (N) runs continuously WiFi 2.4GHz only – 5GHz networks are not supported Installation by electrician recommended – Due to the high power (up to 63A) Home Assistant via LocalTuya – Requires technical configuration; for easier integration: choose the MOES A5 (Zigbee) IP20 – Only suitable for closed meter cupboard or installation housing ❓ Frequently Asked Questions (
