ACNet

Troubleshooting

Start from the message in the app. A missing reply is not proof that a device is offline.

Updated 5 October 2026

Missing devices or names

  1. Confirm Local Network is allowed for ACNet.
  2. Check the range under Scan options. Only that range is contacted.
  3. Try Thorough or Gentle if devices answer late.
  4. Read Details on the scan for what was attempted.
  5. Open the device. A name appears only when the device reported one or you set a label. A type appears only when the device stated what it is.

What the result means

Sleeping phones, firewalls and guest or client-isolated networks often stay silent. ACNet retries a silent host once. A host that stays silent is not listed.

Denied permissions

  1. Local Network: Settings › Privacy & Security › Local Network.
  2. Notifications: the iOS Settings app, only if you chose notifications for a rule.
  3. Background App Refresh: Settings › General › Background App Refresh, for all apps and for ACNet.
  4. Location is optional and is read once, only when you tap the place action in a profile.

What the result means

Settings › Permissions in ACNet shows each state and where iOS lets you change it.

Profile does not match

  1. A similar range is only a suggestion. Tap This network is … to confirm.
  2. If several profiles fit, automation pauses until you choose.
  3. On an IPv4-only network, confirm again after the connection changes. Confirmation lasts at most 12 hours.

What the result means

Rules do not run on an unconfirmed network. The rule state Waiting names the action that resolves it.

Notifications and background checks

  1. Open the rule and check delivery: list only sends no notification.
  2. Allow notifications for ACNet if you chose them.
  3. Turn off Low Power Mode if you expect Background App Refresh.
  4. Open ACNet again if you force-quit it. Background checks stay stopped until then.
  5. After a restart, checks wait until the iPhone has been unlocked once.

What the result means

The profile shows when iOS last ran a background check and what it did. That is not a promise of the next run. A check that iOS ends early is recorded as interrupted and reports no changes. If the gateway is silent too, the check is network unavailable and is not counted as the device failing.
