Perfect integration for Home Automation
I now have a few Mercator Ikuu products and have been very impressed with the quality and integration. I don't use a Mercator hub for my devices as they are Zigbee compliant I'm able to use Zigbee2MQTT and integrate with Home Assistant very easily.
One thing to note, is this device appears as 2 x double GPO. So you will have GPO 1, switch 1 & 2, and GPO 2, switch 1 &2. Not an issue, just something to note when naming/configuring.
