When we purchased our new house 5 years ago, we had a Tesla PowerWall installed. It came with a Telstra 3G SIM card and when they installed it, I told them to connect it via Ethernet. The technician refused, saying that it has 3G and doesn’t need to be connect to the home network at all.

I received a text from Tesla this morning, telling me that our PowerWall will not be covered by warranty when Telstra kill 3G at the end of next month.

I then received an email from Tesla (that looked like Spam).

I then receive a phone call from Tesla.

I mentioned that I don’t have WiFi coverage in my garage and they told me to move my router. I told them that I instructed the technician to connect via Ethernet originally and they said that I would need to get the technician back out to connect it.

I am not allowed to plug Ethernet into it without voiding warranty and I need to plug Ethernet into it to prevent the warranty from being void.
