Problem controlling my Set Top Box via universal remote controller
I have a question to ask pertaining to my project to transform my house into a smart home. I have this Smart home all in one universal controller: Broadlink RM Pro. My universal controller is compatible with IR & RF capabilities with dual IR band (meaning it reads and transmits 33-43 KHz & 44-60 KHz) , which I was able to learn and control all of my remotes (eg my LG TV, DVD player, fans, radio, standing Light) in my living room, and get all of them to work, except my Starhub Set Top Box. FYI this entire post was only about attempting to learn the On/Off function of the box.
Upon a few researches & experiments, I learnt that my Set Top Box's remote control: CA276 emits regular IR frequency, and my universal controller had been able to learn and replicate the IR code. However, after attempting to turn on the Set Top Box via my universal controller, it still doesn't work no matter what. I thought that the signal could be a combination of codes and I trield to save the codes while long pressing the on/off button of the CA276.
I suspected the IR line of sight could be blocked or too far away, so I moved my universal controller directly in front of the Set Top Box. Still doesn't work. (Attempted to control my other devices and they still work perfectly)
I thought the Set Top Box malfunctioned as it coudn't read any remotes anymore so I restarted the box, tried to use the CA276 to turn on. It still worked perfectly.
If anyone knows what am I missing here please help to educate me. I doubt that the IR frequency is encrypted cause it's just an ordinary remote and my universal remote controller had been able to receive and emit the signal, but the Set Top Box just couldn't react.
Thanks in advance for your comments and advice.
P.S: I am using a Starhub set top box DCI82SHB, CA276 remote.
