Can I use my phone as a remote if I don't have a smart TV?

Provided that you are willing to download an app—or purchase some physical hardware—you can certainly use your phone as a remote for a non-smart TV. If your phone has an IR (infrared) blaster, you're definitely in luck. If not, purchasing a separate IR blaster that connects to your phone is your only option.7 abr 2021

How can I use my phone as a remote for a non smart TV?

If you have a IR blaster in your phone, then you can control almost any TV though it can act like a TV remote. There is an app named “Peel Remote”, download it and use that. If your TV has a wifi connection, then using same app connect both, your mobile and TV to same wifi connection and use that app as a remote.
