With a 50-foot connection, you have 100 feet of wire round trip. Also, there will be some voltage drop in the 50A circuit breaker and its connection to your panel. And the main breaker and its connection to your local utility transformer, etc.
In the meantime, if the "connected" features of the LCHCS ever do become important, many are installing a device that can't be connected or updated without taking it apart and plugging in an Ethernet cable.
Mine's going in and out of Monitor state as well lately. My PAAK phone is in a cradle 20ft away. I'll turn off my phone and see if the car goes back to sleep.
My 2022 has only been gone to service twice, both times for its yearly annual maintenance. I've had a few minor items addressed at the same time. It doesn't squeak or rattle. It's been fine.
It'd be cool if Lucid would at least fix the LCHCS home page units typo, and that problem with 192.168.1.x networks. At least show it's still cared about.
