If the air conditioner or home electronics device has an infrared (IR) remote controller, yes.
For air conditioners, we have 2 levels of support.
A) We prepare a database of IR signals for manufacturers, air conditioner models and you pick which one is installed in your room. We'll provide a way to filter the list so that you don't have to go through the loooong list. After you pick a model, you can control the air conditioner from the app.
B) You press a button on the remote controller, Remo app "learns" that IR signal, and creates a button in the app to resend it.
We'll at least provide B for all electronics devices (including TVs or others) that have IR remote controllers.
If the air conditioner, or your electronics device doesn't have an IR remote controller, no, but we'll cover you when the "Nature Remo Power Plug" is ready.
