Thanks for the info.I only purchased it once and have it on two watches
Hi, yep the Bluetooth connection to the Tesla is a bit fiddly sometimes. I've constantly been trying to improve it. A big part of the issue is that by default Watt Key runs in the background and tries to automatically connect to your Tesla. Big issue with this is that Android's Wear OS aggressively kills apps running in the background to save power. This is a great feature but is a real pain for Watt Key trying to auto connect. In practice I usually have my phone auto connecting and unlocking the Tesla so I added a feature to Watt Key to turn off the auto connect in the settings menu of Watt Key. When I want to use Watt Key specifically, I open it manually on my watch and it works very reliably.Hi. I'm interested in Watt Key. However, I've seen mentions of where the phone bluetooth connection with the car is sometimes unreliable, and so they need to keep the keycard with them as a backup. Is that a situation where the NFC key function in Watt Time is useful? Are there any plans of adding the NFC key function to Watt Key? The rest of the functions of Watt Time sound great, but I really dislike the lag with the API and I sometimes park in an area with no internet connection. Thanks!
Watt Time and Watt Key are stand alone apps, they don't require the other to work. Watt Time purely uses an internet connection to talk to the Tesla servers which in turn then talk to your car. Watt Key talks directly to your car over Bluetooth. Biggest difference being the internet based Tesla API has many, many features whereas the Bluetooth protocol only supports basic functions like lock/unlock, open frunk/trunk/chargeport etc.Also, am I going to be waking up my car with watt key/time randomly connecting? I have tessie already using my api. I dont want a bunch of apps waking the car up randomly. Thanks!
I'm glad you like the app. Yes v4.1 is currently the latest version. I'm not sure the companies renting out the Tesla's would like people adding their watch as a Bluetooth key, as if you ever found that Tesla on the street (after having rented it out) and assuming they didn't delete the key you added from the Locks menu then you'd be able to unlock that car and drive away.Watt keyyy! I was sold in a second. I literally stopped at the costco omw to the business trip just to upgraded my watch to galaxy watch 5 to try and use this app.
This would be perfect when im renting out the tesla or renting a tesla from hertz or others when im in different city.
There was one time i rented MY in vancouver and they only give you card key. It was such a hassle locking unlocking and starting the vehicle. (i was so used to at just getting in and start the vehicle without using the card key) everytime when i was in a rental i had to dig out the key to open the door and place the card to start the vehicle.
Im actually heading to the airport for the business trip and i have a tesla MY booked so im going to try this.
And like i said if you advertise this to those renters on turo and people renting from hertz in canada it would sell really well.
One thing though i tried to look up the instruction on the website. Its definitely not enough information...
It would nice if you could give some detail instruction on each features on watt key and the conditions for it to work.
I was wondering to be able to use the auto unlock and locking do you have to set the watch as a priority bluetooth device or do you even have to add the watch on bluetooth device list?
Because when i authorized it it was connected and i was able to use the buttons even when it wasnt on the bluetooth device it was only showing up on lock list.
I will be picking up my rental Tesla in couple hours i will check it out if it works and the features i could use and keep you updated as well.
Thanks for the awesome app!
Ps. On my watch watt key shows version 4.1 is this the latest version?
I'll add NFC to Watt Key in the next update as a backup feature that's off by default. Just need to test it won't clash with Watt Time also running an NFC key. Whoops! I can add a confirmation to that command so it asks first before executing it (the frunk and trunk commands can ask for a confirmation before opening also - check the settings menu).Just downloaded Watt Key for my M3LR seems to be working great! Agree it would be awesome to have nfc in Watt Key as a backup.
Is there any way to remove certain buttons so I don't accidentally press it? (I.e unlatch drivers door). As I've just accidentally pressed it and had to go out to close the door
Planning to purely use my watch as an offline key when I go park somewhere for cycling, and to quickly unlock charger as I'm heading out the door - will see how practical it is compared to using my key fob.
If you have it paired to your phone no. If you are out of range of your phone and want to use it then yes you need internet. Watt Time goes through the internet where as Watt Key is more like a phone key and local bluetooth.Does watt time require lte on the watch to use?
You need to scan your key card in order to authorize addition of your watch as a bluetooth key, just like you did with your phone. Your watch will then show up in the list of keys.I just purchased watt key and I'm not able to pair my watch as a key. I followed the instructions on your site and I'm getting a notification on my watch saying watt time nfc authorized. However, my car doesn't recognize the watch. It just stays at the screen asking to scan behind cupholder. My watch is a fossil gen 3 explorist on wear os 2.
The watch needs to be scanned before the key. It doesn't recognize the watch so it never asks for the key.You need to scan your key card in order to authorize addition of your watch as a bluetooth key, just like you did with your phone. Your watch will then show up in the list of keys.
From the Watt Key developer's website:The watch needs to be scanned before the key. It doesn't recognize the watch so it never asks for the key.
How to Connect to Your Tesla
When you first open Watt Key it’ll present you with a small tutorial on how to do this. Once you follow this tutorial or skip it you’ll be presented with a request to allow the app to use Location/Bluetooth permissions. You must accept this request so Watt Key can access the watch’s Bluetooth. After accepting you’ll see a list appear and your watch will begin scanning Bluetooth for nearby Tesla’s.
If you’re near your Tesla you should see it come up on this list. Tesla’s are listed by their Bluetooth name given to them by Tesla. This Bluetooth name is a representation (SHA1) of the Tesla’s VIN. If there’s multiple Tesla’s around you it may be difficult to figure out which is yours. To help you can look at the signal strength indicator listed for each Tesla, the one with the strongest signal should be the Tesla you’re standing closest to. You can also manually enter your Tesla’s VIN so Watt Key can connect directly to it.
Once you’ve pressed on your Tesla or manually entered the VIN, Watt Key will generate a cryptographic key that it’ll use to authorize itself with your car. On completion it’ll start connecting to your Tesla and request to be added to your Tesla as a key. Your Tesla requires you to authorize this by swiping your NFC key card on either the door pillar or on the center console. Watt Key will prompt you to do this when the Tesla asks for permission. After swiping your key your watch will now be added as a key in the Locks section of the Car menu!
That's your problem we use the watch Bluetooth for connecting not watch nfc. Watch shouldn't have to touch anything only tesla that touches is the keycard.The watch needs to be scanned before the key. It doesn't recognize the watch so it never asks for the key.
The developers website states watt key uses BT but watt time uses NFC. I bought watt time for the additional functions.That's your problem we use the watch Bluetooth for connecting not watch nfc. Watch shouldn't have to touch anything only tesla that touches is the keycard.
