The Tedee integration lets you connect your Tedee smart lock to Nowistay so that unique PIN codes are automatically generated for every guest booking. No more coordinating key handoffs, hiding lockboxes, or manually programming access codes. Nowistay creates, updates, and removes the guest code for you.
Each guest receives a temporary code that only works during their stay, from check-in to check-out. If a booking changes, the code validity window is updated. If a booking is cancelled or moved back to pending, the code is revoked.
Important: only one smart lock can be assigned per property. If you use multiple lock brands, such as Tedee, Nuki, igloohome, or TTLock, you need to choose one smart lock provider per property.
Before connecting Tedee to Nowistay, make sure you have:
If the keypad is not paired, or if the lock cannot be reached remotely, Nowistay will not be able to create, update, or delete PIN codes reliably.
Open the Tedee app and check that the lock you want to use is installed, paired with its keypad, and visible in your account. If you manage several locks, give each lock a clear name, such as the property name or unit number. This makes the assignment step much easier inside Nowistay.
You can also create a manual test PIN in Tedee first to confirm that the keypad works correctly. Once the integration is connected, Nowistay will create the guest PINs automatically.
Go to Integrations from your Nowistay dashboard. Under the Smart locks section, find the Tedee card and click Connect.

Tedee uses a secure OAuth connection. This means you do not need to copy a client ID, secret, API key, or password into Nowistay. Instead, Nowistay redirects you to Tedee, where you sign in and approve the connection.

If the authorization succeeds, your Tedee account name appears as connected. If you cancel the authorization, close the Tedee page, or use an account that does not have access to the lock, simply restart the connection from the Tedee drawer.
Once connected, the drawer shows the Lock assignments section with the list of eligible properties.
For each property you want to equip with Tedee access:
Important: each property can only have one active smart lock assignment at a time, regardless of the brand. If the property already has a Nuki, igloohome, or TTLock lock assigned, remove it first before assigning a Tedee lock.
To change the assigned lock later, select a different lock from the dropdown. To remove an assignment, click Remove.

Once a Tedee lock is assigned to a property, Nowistay handles the code lifecycle automatically:
For each lock, you can choose how many days before check-in Nowistay should generate and send the code to the lock. This setting appears below the lock selector, labeled Generate codes X days before arrival.
You can set any value between 1 and 14 days. The default is 5 days.
Examples:
If the code cannot be generated on the scheduled day, for example because the lock, keypad, or bridge is temporarily offline, Nowistay will automatically retry every hour until the code is successfully created, up to midnight on the check-in day in the property timezone.
The access margin controls how much extra time the code is valid before check-in and after check-out. This setting appears below the generation timing, labeled Access margin.
You can set any value between 0 and 240 minutes, which is 4 hours. The default is 30 minutes.
The margin is applied symmetrically: the same duration is added before check-in and after check-out.
Examples:
The code validity window is based on the check-in and check-out times set for the booking. Nowistay uses the property timezone and checks:
Negotiated times are capped to reasonable limits so a guest code cannot be extended too far outside the planned stay.
If Nowistay cannot generate a Tedee PIN, the system keeps retrying every hour:
The generated PIN is automatically available in your automated guest messages through the {{smartlock_code}} variable. The legacy {{nuki_code}} variable also works for backward compatibility.
For example, you can create a check-in message that includes:
Your door code is {{smartlock_code}}. It will be active from check-in to check-out. Enter the code on the Tedee keypad to unlock the door.
This way, your guests receive their access code automatically without you needing to copy it from Tedee.
By default, Nowistay generates a random 6-digit PIN for each booking. You can also choose to use the last 6 digits of the guest phone number, which can make the code easier for guests to remember.
To change this setting, open the Tedee settings for the property and look for the Code source dropdown. You have two options:
Tedee PINs must follow Tedee rules: they must be numeric, contain 5 to 8 digits, include at least 3 different digits, and cannot be a simple ascending or descending sequence such as 123456 or 654321. Nowistay uses 6-digit codes. If the guest phone number is missing, too short, already used, or rejected by Tedee rules, Nowistay automatically falls back to a random code.
If you need to disconnect your Tedee account, open the Tedee panel from Integrations and click Disconnect next to your connected account name.
Disconnecting will:
Active codes for current guests remain valid until they expire naturally or are removed by the normal booking lifecycle.
Check that the lock is visible in the Tedee account you connected, that your account has owner or administrator access, and that the lock is online. Also make sure the keypad is paired and the lock can be managed remotely.
Only properties using Nowistay PMS and an active AI Assistant subscription appear in the smart lock assignment list. If a property is connected through a direct OTA integration or another PMS connector, it will not appear.
Make sure the booking is confirmed, the lock assignment is active, and the code generation date has arrived. If Tedee is temporarily unreachable, Nowistay retries automatically and sends an email alert if the issue continues until the evening before check-in.
Restart the connection from the Tedee drawer and sign in with the Tedee account that owns or administers the lock. If your browser blocks popups or redirects, allow the Tedee sign-in page and try again.
