Your website doesn’t work!

Your website doesn’t work! And now app have glitches

Disappointed

I have waited over a week for this app to show me something other than what I already see with the Tesla app. The only consistent feature on this app is that it continues to disconnect from the car multiple times a day.

Too obsessed with reporting and not basics

Used to be a useful tool but the developers are too obsessed with FSD and other reporting yet basics like home charging no longer works. The Add time of day charging has stopped functioning but nothing seems to be done about it. Very good on trip reporting but that’s about all value to me now.

Phone Won’t Recognize Texan Pro

I installed TezLab and paid for 1 year subscription for TezLab Pro. Even though the purchase shows in my subscription list, the app does not recognize this purchase. Every time I click on an option in the app, it tells me I need to subscribe to Pro. I sent an email to support but have not received a response. Very disappointed. I’m hoping someone from TezLab reads this and contacts me.

Incredible data

I can make .csv files and use them in python to make fun graphs of my car usage. This app is amazing. So much more from driving maps to weekly reports. It’s superior to the Tesla main app and I worked at Tesla.

Edit saved me 500$!

Was connected to a neighbors plug in duplex and they claimed way more usage and TezLab won when my data was presented to the landlord !

And I have years of data I can toss into an LLM and visualize for great sentimental value datasets
