*** Compiled with SDK 8.1.1 *** It works well on my Fenix watch. I can't test on other devices beside through the Simulator. If you're having issues, instead of leaving a bad review, contact me through the Contact Dev button and I'll see what I can do.

Above what the PixelPathos version offers, this version adds the Pulse Oxymeter sensor, Recovery Time Left, Body Battery, Stress Level, Solar Intensity and Floor climbs as a data field; Body Battery and Stress Level as Goal Meters; color coded numeric batterie level and Do Not Disturb as indicators; customizable theme color; Complications (including launching their corresponding widget directly from the watchface!); added support for additional watches, like the Fenix 8, Enduro3,  Fenix 7 Pro, Fenix 7, Epix Gen 2, Descent Mk1, Mk2 and Mk2s, D2 Delta, D2 Delta PX, D2 Delta S, Forerunner 165, 955 / Solar, 255, 255 Music, 255s, 255s Music, 265. 265s, 965, Enduro, MARQ MARQ (Gen 2 - all models) , Venu SQ 2 and Venu SQ 2 Music, Venu 3, VivoActive 5 as well as bug fixes that were in the original Pixel Pathos code and other small improvements.

But, the big change of this version, and as the name implies, is the addition of information from a Tesla vehicle which is activated by choosing the indicator 'Tesla Info'. If the vehicle is awake, it will display the battery charge level as a percentage, followed by a '+' sign if it's being actively charged. It will also cycle to P on/off for the Preconditioning Status, S on/off for Sentry Status and the vehicle's inside temperature. If the car is asleep, a 's' will be displayed after the battery level and it will only cycle between that and P on/off. If an error is received from the car, it will be displayed in pink instead of the battery level. Scan interval is the standard 5 minutes so give it at least 15 minutes at start to get the access to the car and poll its status.

You'll need to generate at least a refresh token and enter it in the watch face parameter to give access to your vehicle status. You can get a token through online services or phone apps like Tesla Token. If you give it also an access token, the refresh time before starting to capture data will be decreased by 5 minutes. Make sure your vehicle is awake for at least 15 minutes when you first launch the watch with the token set so it can connect to it. It will NOT wake the vehicle to retrieve any of the info and it does NOT prevent the vehicle from falling asleep.

Now support Complications, including from Tesla-Link.

Mind you, these changes were done for myself for my watch. I'm sharing here so others can benefit from it.

NOTE:
The Garmin Weather code needs an API level 3.2 and above to work.
The ¨Pulse Ox code needs API level 3.2 and above to work (and a pulse Ox sensor in the watch)
If your watch is not at the required API level or higher (see https://developer.garmin.com/connect-iq/compatible-devices/), then you're better off with the original Crystal watch face as the added code will be of no use to you and might even not work because of the added memory requirement for features of no use to you. The only additional feature that this watch face will give you is the numerical battery indicator.
