Zigbee signal converter received in one week in grouped order. Seems to work properly and installed in seconds under Smartlife with my Zigbee hub. Alexa and Google skills are automatically installed.
No problem for the moment with my Zigbee network capable of transmitting the signal of a sensor fixed in a Letter box located plus 30 meters at the entrance of the property.

I buy 8 units but i only recived 7 units

perfect

This can be an inexpensive replacement of the original BRC1E52A7 wired controller connected to one of DAIKIN VRV indoor units, if you need to control it wirelessly. It connects via WiFi to Smart Life phone app and allows On/Off switching, remote control of a temperature, fan speed and mode selection.
It can be connected to Google home, but unfortunately only On/Off and fan speed options are available there. There is no temperature selection.
Be aware that it is not a complete replacement of BRC1E52A7, it doesn’t have all the advanced options needed for controlling outdoor unit etc., so I wouldn’t replace all original BRC1E52A7 controllers with it.
It also emits some annoying a ticking noise, not very loud, but noticeable. But it can probably be mitigated by fully integrating this unit into a wall. I didn’t finish the installation yet.

If it is set then it is actually quite good. The support is catastrophic, no response at all or assistance
