EARU WiFi DIN Rail Relay 63A – Tuya Switch with Energy Metering

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.

Does the EAKCB-TM work with Home Assistant?

Yes, via the LocalTuya integration. This requires some technical configuration. For a fully local and simpler Home Assistant integration without the cloud, check out the MOES A5 (Zigbee) .

What does the device do after a power outage?

The EAKCB-TM has an adjustable power failure memory: choose from always on, always off, or remember the previous state.

Does the device also work when there is WiFi interference?

The local physical switch on the device always works, even without internet. Automations and app control require an active Wi-Fi connection.

What is the difference with the MOES A5?

The EAKCB-TM works via Wi-Fi and doesn't require a Zigbee hub – ideal for easy setup. The MOES A5 works via Zigbee, integrates fully locally and cloud-free with Home Assistant via Zigbee2MQTT, and also functions as a Zigbee router.
