Hey Rob, I managed to get Watt Key going faster than I thought. I've released a new update with the new end-to-end encryption command protocol if you'd like to update Watt Key and readd your vehicle. Watt Key requires your Tesla's VIN now for authentication so I've added a companion phone app...

Yep! Tesla has been rolling out the new end-to-end encryption to cars faster than they had told us they would. This new encryption is very different and much more complex than the previous implementation. I've been working on getting it into my apps in my spare time but it's going to take a...

Hi there, Unfortunately Tesla has started to make the move to the end-to-end encrypted commands faster than I had expected and as a result both of my apps (Watt Time and Watt Key) cannot send commands anymore. I will work on getting them both working again but it may take some time. Very sorry.

Hi all! You may notice an update to Watt Time today which will ask you to login again. This is because Watt Time now uses the official Tesla API and requires you to authorize Watt Time to access your Tesla's data. You'll first need to create a new account on my website and then link that account...

Yep. I've got a Galaxy Watch 6 and it's working well. Can you please double check you've got the latest version of Watt Time? Then go into the Settings menu in Watt Time and press the "Reset NFC key" button. After you see a message saying it successfully regenerated a new key can you try the...

Ah right! There's currently no way to disable this. Watt Key sends an automatic lock message as you walk away from your Tesla. I'm just fighting with Google over an update to Watt Key at the moment (they're being very picky about the design/look of watch apps). After I sort that out, I'll add an...

That's a very good question. I can't figure out how to do it on my Samsung Galaxy Watch 6. I think I've figure out how to clear the cache though: 1. Go into your watch's settings 2. Scroll down to "Apps" and tap on that 3. Tap on "App list" 4. Find "Google Play Store" and tap on it 5. Scroll...

Can you try to sign out and back into Google on your watch? That might reset things.

Google says that error is usually because the Google Play app cache is corrupted. Can you try turn your watch off and back on and see if that helps? Otherwise if you can go into the settings on your watch and see if you can clear the cache for Google Play.

Hi, no worries! Actually it's me that's sorry, as it turns out I had forgot to ask for fine location permission on newer WearOS versions. This location permission is required as the Tesla gets filtered out of the Bluetooth search results without it. If you open Google Play app on your watch and...

Thanks for attaching the logcat, very useful! It looks like Watt Key is successfully starting a BLE scan and results are coming in. Could you please download this app: nRF Connect for Mobile - Apps on Google Play Once you've got that app open do a BLE scan and see if your Tesla comes up, its...

Sorry I don't have the time 😥 Garmin watch development is quite different to Android development.

Sorry about that! Hmm just for the basics; are Bluetooth and Location services enabled? Did the app prompt you to give it access to Location when it first started to scan for your Tesla? You can double check its permissions in the "App" section of the watch settings. I'll have a look into it on...

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...

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...

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...

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...

Unfortunately I recently received an email from Google saying: So after all the effort of implementing Google Assistant it seems they won't allow it on Wear OS, despite it initially working and them then disabling it... :mad: Sorry about that. I'll keep tabs on this, hopefully Google pulls...

I'm glad the NFC is working better for you! The "More info" section doesn't live update while you're viewing it. It refreshes when you first open the app and then every 30 seconds it'll pull the latest data from the vehicle (as long as you're not in any sub menu), unless it falls asleep in which...

I'm glad Watt Time has been useful for you! Sorry about that problem with Watt Key. If you open the Watt Key app and try to open the frunk or trunk from there, does it work? I'll have a test with my Tesla and see if I can replicate the problem.

I think a few hours is a bit of an exaggeration. My Samsung Galaxy Watch 5 still lasts a whole day with Watt Key running constantly. Unfortunately the reality of having a constant Bluetooth detection running uses power and there's no way around it. The official Tesla app has to do this as well...

Nice, I'm glad it's working well for you! Sorry about that, would've broken it in my latest update. I'll fix it up and get a new update out ASAP.

Should be pretty immediate when you're close to your Tesla. If it's the first time connecting to your Tesla since you powered on your watch then you need to open up Watt Key first. It'll then start a low power scan to look for your Tesla to come into range. I added a force connect button (just...

Sorry about these issues! For the NFC error, it seems that Watt Time's cryptographic key wasn't correctly generated. If you uninstall and reinstall Watt Time it'll generate a new key and should fix this issue. You'll just need to add it to your Tesla again. When you mention getting the watch...

Hi all, I've just added Google Assistant shortcuts to Watt Time and Watt Key (English only currently). The shortcuts are live on Watt Time now (v5.4) and should be available on Watt Key soon (v3.3 - waiting for Google approval). Give it a go and let me know how it works for you! For me it keeps...

Annoyingly it doesn't show up on the Google Play Store phone app because it's a watch only app (this is what Google told me). So instead you need to search for Watt Key on the Google Play Store watch app or the Google Play Store website and get it from there.

Happy holidays everyone! I've just released updates for Watt Time and Watt Key. Watt Time: * Summon support is out of beta and ready to be used (thanks Tesla for giving NZ EAP for a month!) * Added fart and bioweapon defense mode commands (to protect yourself from the farts) Watt Key: * Added...

I'm glad you like the apps! Ah sorry about that issue. I'm currently doing a large overhall of Watt Key including an adjustment to make it only connect when you're very close to your car (instead of as soon as it gets signal). As it's quite a big change I'm having to do lots of testing but...

I just responded to you via email but I'll say it here for anyone having a similar issue. The NFC readers on the Tesla are tuned to only read from a very short distance, this is to avoid it accidentally reading an NFC tag, also a key card is quite easy to press directly up to the glass on the B...

I believe you can also remove and re add the tile. I'm currently working on fixing this! Hopefully I can push an update soon to fix it.

Hmm there does seem to be some odd delay between my app updating the tile and it actually updating, despite me telling it to force update. Glad a reset fixed it. I've found removing the tile and readding it works too. Sorry about it timing out still. I'll look into it tonight. The timeout is...

I've just released an update to Watt Time that allows you to add up to 7 functions to the tile now :) I've also made the app retry the connection to the Tesla servers much quicker so hopefully it'll wake the car and fetch data faster now. I also fixed a crash when using the summon "come to me"...

Unfortunately Google Play Store phone app won't show Watt Key as it's a watch only app. Search Watt Key on Google Play Store on your watch or in a browser on your computer and you should find it 😊

Cool 😊 No, there's no limitation. I think I just wanted to keep the tile realitively simple and clean. I'll add option to add more buttons and put it in the next app update.

Yep. If you hold down the button you want to change then it'll show a list of functions you can replace it with. Tesla double the open charge port functionality with the unlock charger functionality, so if you've got a charger plugged in and "open the chargeport" it'll unlock the charger.

Sorry about that. I'll have a dig into the code and see if I can spot anything that might be causing this. I've got a Samsung Galaxy Watch 4 too and I noticed I had to press the watch right on the center console and door pillar and hold it there steady for a good couple seconds for it to register.

Google Play can take a few days to roll out updates to all regions. Hopefully it'll come through soon. Sometimes I find uninstalling and installing again forces Google Play to look for the latest version.

Heads up to any users of Watt Time; I've just released v4.7 that now includes NFC support so you can add your watch as an NFC key to your Tesla. Simply go into the Locks section of the Car menu in your Tesla, click the "+" button and then place your watch on the center console so your car can...

Yep! I don't have FSD myself though so I'll need to find someone to beta test it for me.

Nope, they're both standalone apps. Watt Key uses the Tesla's Bluetooth protocol, whereas Watt Time uses Tesla's API (which requires internet access and for Tesla's servers to be up and running). The Bluetooth protocol can only do the most basic functions: unlock/lock, open frunk, open/close...

The only time Watt Time will wake your car is when you first open the app, if you left the app open it would only continue to pull data from it while it was still awake. Tesla recently updated their API to include a latest cached data endpoint so I can get the latest data for the car without...

Hmm interesting! Thanks for letting me know. I'll look into it and try get it fixed asap :)

Cool, glad it's working well for you! For some reason on the Google Play app it shows as incompatible, but the Google Play watch app and Google Play in the web browser doesn't have this issue. I'm currently talking with Google to get it fixed. If anyone gets this issue either open Google Play...

Yep can do. I'll add it in the next release. I'm currently working on adding Google Assistant voice commands so hopefully I can get that in the next release too (Also will be adding voice commands to Watt Time).

Same here. Was just testing this today. I assume there's an upcoming car firmware update that'll enable it to send out the data before going to sleep.

Alrighty everyone, I've released my new app Watt Key - Get it on Google Play Store for Wear OS watches. Only works on Model 3 and Y and refresh Model S and X. Unlike my Watt Time app, this app controls the car via it's Bluetooth Low Energy protocol. The huge benefit here is that the commands...

Hi all! I've just finished work on my new app: Watt Key. It essentially turns your watch into a Bluetooth keyfob. It runs in the background on your watch so as you walk towards your car it'll automatically unlock and you can drive away. As you walk away it'll disconnect and lock the car. You can...

Thanks heaps for putting in the work to reverse engineer and document the BLE communication! I'll take a look at the python library, I'm sure it'll help me out.

Just a quick note to anyone who's confused when they next look for my app: I was unfortunately forced by Google to change the name of my app and my logo as they said I was attempting to impersonate Tesla. So the app is now called Watt Time (as in, Watt Time is it?! Tesla Time 😅), and the logo is...

No worries, I'm happy it's proving useful for you! I would definitely love to implement that, unfortunately here in New Zealand we don't have that feature yet so I'm unable to even start figuring out how it's done. My big three improvements I'm trying/hoping to figure out are: Bluetooth...
