Onn Roku TV Remote App for iPhone: Control It With No Pairing

Good news first: most Walmart onn. televisions run Roku, and Roku is the single easiest platform to control from a phone. Roku devices accept commands from apps on the same WiFi with no pairing step at all — no PIN, no Allow prompt, no account. If your iPhone and the TV share a network, you’re back in control in under a minute.

One check before you start: an onn. set is a Roku TV if it shows the Roku home grid (purple background, channel tiles). Walmart also sells onn. Google TV models and streaming boxes — a different platform with a different setup (covered here). This guide is for the Roku ones, which are still the majority of onn. TVs sold.

The free options first

You don’t strictly need a third-party app to control an onn. Roku TV:

The TV’s own buttons. Every onn. Roku TV keeps a small button on or under the panel — usually the bottom-center edge or the back-right corner. On many onn. models it’s a single button: a quick press powers on, and holding it cycles input. It’s enough to get something on tonight while you sort out a remote.
The official Roku app (free, from Apple). It has a remote built in, plus private listening through your headphones. It’s a larger, multi-purpose app that nudges you toward a Roku account, but it’s a genuinely honest, capable choice.

Both work. Where a dedicated remote app earns its place is speed and focus — it opens straight onto the D-pad instead of a home screen full of channel promos.

Controlling your onn. Roku TV from the iPhone

Put your iPhone on the same WiFi the onn. TV uses — the real network, not the guest one, with any VPN switched off.
Open Remote Pro and scan. Every Roku on the network shows up by name, so an onn. Roku TV usually appears as something like “onn. Roku TV”.
Tap it. That’s the entire setup. You’re immediately controlling the TV: D-pad, home, back, playback — and your iPhone keyboard for search boxes and sign-in fields, which beats hunting letters on an on-screen grid.
Volume, mute and power all work, because on an onn. Roku TV the Roku is the television. (That’s the difference from a Roku stick plugged into some other TV, where volume has to go out to that TV’s own hardware — here’s why.)

If the scan comes up empty

Almost always a network split — the phone landed on a different network than the TV (guest WiFi, a separate 2.4GHz/5GHz band name, or a brand-new router). Walk the checklist in order: Roku remote app can’t find your TV.

If the TV shows up but ignores the presses

The onn. appears in the scan, yet button taps bounce off? That Roku has app control switched off by policy. One setting fixes it — on the TV: Settings → System → Advanced system settings → Control by mobile apps → Network access → Default. Full walkthrough: the control-by-mobile-apps fix. (You’ll need some way to navigate there — the panel button or a found-one-last-time remote.)

Lost the onn.’s remote entirely?

If the remote is simply gone, the phone-as-remote route above is your fastest fix — no pairing means nothing to re-sync. The one hard case is a lost remote plus a WiFi change (new router, new house), where the TV isn’t on any network for an app to reach. The escape routes — Ethernet, or recreating the old network as a hotspot — are laid out in the lost Roku remote guide.

The same zero-pairing trick works on every other Roku-based brand too — if there’s a second set in the house, here’s the Sharp Roku TV remote app for iPhone walkthrough. Once you’re back in, Remote Pro also covers your Samsung, Fire TV and Android TV hardware from the same screen — handy if the onn. Roku TV isn’t the only set in the house.
