Intro

Anyone near a wall panel or tablet with Always-On Display on can open Settings. To stop people from changing settings, you can set up an admin code.
The admin code makes a device harder to change, but it isn’t a complete lock. For a device in a shared or public space, like a reception, a holiday rental or a home with guests, also:
  • Set it up as a control panel, so it can’t change the accessories or open the property’s admin settings. See Control Panels and Device Groups.
  • Lock the tablet to Zendo, so nobody can open other apps or the tablet’s own settings. On an iPad or iPhone, use Guided Access.
  • Keep it on its own network, for example a separate VLAN, so no other devices can reach it.

​
Set, change or remove it

  1. Tap
  2. Tap “Settings”
  3. Tap “Device Settings”
  4. Tap “Admin Code”
  5. Tap “Set Code”, choose 4, 6 or 8 digits, then enter the code twice.
To change or remove it, do the same and tap “Change Code” or “Remove Code”. You’ll need the code to open Settings first. You can also set it from your hub. See Set or remove a code from your hub.

​
Good to know

  • Wrong codes: after a few wrong tries, the keypad waits a little before the next one, up to a minute.
  • One property only: a device with an admin code can’t join another property.
  • Always-On Display can’t be turned off while a code is set.
  • Not the screen lock: the screen lock PIN covers the whole screen. The admin code only covers Settings.
  • See which devices have one: if an installer set up Zendo at your property, “Control Panels” shows whether each device has an admin code, even while the device is offline. See Check a device’s details.

​
Forgot the admin code?

Your hub keeps a copy of the code to help you regain access to a device, even while the device is offline.
  1. Sign in to Home Assistant as an administrator.
  2. Go to Developer Tools > Actions.
  3. Run zendo.managed_device_admin_code_get.
  4. The code is admin_code in the response.
If status is unknown, Home Assistant doesn’t have the code.
  1. Create an Advanced Flow.
  2. Add Get admin code of Zendo device and pick the device.
  3. Log the code from the card tag (e.g. by creating a timeline event).
  4. Start the flow.
If your hub doesn’t have the code and your device is online, you can set a new code from your hub. If your wall panel is offline, please contact your installer to reset the code. For phones and tablets, please reinstall Zendo.

​
Set or remove a code from your hub

You can set a code from your hub for all the devices that are online. Setting a code replaces the old one.
As an administrator, run zendo.managed_device_admin_code_configure. Put the code in quotes:
To remove the code, use remove: true instead of code:
Use Set admin code for Zendo device or Remove admin code from Zendo device in a flow. Pick one device, a device group, or All devices.
