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

Great product very good quality ideal for curtains works perfectly well. I recommend
