hi yef,
Have you considered the legal repercussions in overriding the landlords legal rights in this matter.?

Yes, its tottaly legal no laws will be broken .

 

Hi,
So asking the landlord to re-enable the disabled functions, is an easy solution.

Hello Eric,this is an intellectual challenge .
i promise to ask him for permission.

 

I reversed out the IR codes for some devices when I wanted to control them using Alexa. While my Alexa control method is no longer supported the way to reverse the codes is still applicable.

I used an D1 mini board based on the ESP8266. You can get these for a few bucks from many sources. They program over a USB cable, and are very well supported when it comes to libraries. You can tack on an IR receiver such as a TSOP4838 and when you point an IR transmitter at it the transmitted codes will appear in your debug window.

Once you have the codes in your pocket you can reuse whatever micro you used to make a controller.

This kind of thing has been done so many times you can just Google a solution.

 

Hello ErnieM,in every I2C component we have command manual so how can i get the command manual to know what kind of commands are there ?
Thanks.

 

IR != I2C Is this a new question?

Have you tried Google to get the manual?

 

Hello ErnieM ,I have found this manual shown bellow.
but it uses reverse engineering to get the codes for the commands.
he broadcasted the remote to the sensor.
Is there a way i could find the codes in some manual?
Its not something TV or AC manufaturers are publishing for their customers.
is there something i could do?
