The light and fan operation well and the packaging was good.
Nevertheless, just like the other clients I notice the absence of the speaker yet indicated in the title.
It becomes a habit on aliexpress to send another product if the one ordered came up short.
However, it would suffice to warn via messaging

The product is low as I want, it protects from high voltage and current, it can be monitored remotely by wifi connection, you can make the settings through the application.

They are clear that battery not included or shipped with product. Aside from that, these are great physical switches that support single, double, and long press. Works well with tuya smartlife and you can easily build out your smart logic using tuya cloud intergrtion.

overall a good price with expected functionality

They work perfectly, Sonoff is a guarantee of quality. I will certainly buy others to integrate the home automation system at home

Fast delivery, individual packaging, the product is undamaged, as described.
