TV Wake Over Wi-Fi

Why power and wake behavior varies by TV model.

Supported Devices Known Limitations Roku Power

Quick Answer

Some TVs cannot wake over Wi-Fi because they stop listening on the network when asleep. Wake support depends on the TV platform, model, firmware, standby settings, power-saving mode, and whether the TV keeps Wi-Fi or Ethernet active during sleep.

Last updated: May 7, 2026.

Why Wake Fails

Cause Effect
Wi-Fi turns off during sleep The app cannot reach the TV until it is manually turned on
Network standby disabled The TV ignores wake commands while asleep
Power-saving mode The TV saves power by reducing network availability
Platform limitation The TV API may not expose wake control to network remotes
HDMI-CEC chain Streaming device power may depend on the TV or receiver

What to Check

  1. Turn on the TV manually and verify normal remote controls work.
  2. Check TV settings for Quick Start, Network Standby, Mobile Device Control, Wake on LAN, or similar options.
  3. Keep the TV and iPhone on the same trusted network.
  4. If available, use Ethernet for more reliable standby wake behavior.
  5. Check the supported devices table for platform-specific notes.

Wake Over Wi-Fi FAQ

Does Ethernet help?

Sometimes. Some TVs keep Ethernet active more reliably than Wi-Fi during standby, but it still depends on TV settings and firmware.

Can app launching work if wake does not?

Yes. App launching can work while the TV is awake even if wake from sleep is limited.

Why did wake work before but stop after an update?

TV firmware updates can change standby, network, and power behavior.

Common questions

Why cannot some TVs wake over Wi-Fi?

When a TV sleeps, it may turn off Wi-Fi or stop listening for network remote commands. Wake support depends on model, firmware, network standby, and power-saving settings.

Can Remote Control for TV force a sleeping TV to wake?

No. The app can only use wake or power behavior exposed by the TV platform and the current network state.

What settings should I check?

Check network standby, quick start, mobile device control, wake over LAN, HDMI-CEC, and power-saving settings if your TV provides them.
