EV Owners: EV home charger / Tariff

Hello fellow EV owners!

I have finally bit the bullet and am moving to all electric (hopefully will be collecting car next week).
I should have really done the full in depth research beforehand but I am a sucker when it comes to visiting a dealership...

Am looking for suggestions as to which home charger to go with.
I was going to go ahead with the OHME pro, but it has no Wi-Fi/Bluetooth connectivity and the included sim is only free for the first 3 years, then you will have to pay a monthly subscription.

Also are there any that allow V2G that is/will be compatible with Octopus?

Finally I am leaning towards untethered as I can then buy a replacement cable if it were ever to get damaged. However, how robust are the cables that are tethered? is there a risk of cable thieves cutting them?

Regarding tariffs, I am assuming intelligent go is the best one?
I am currently on the tracker tariff and am wondering if I were to only charge the car say 2-3 times a week (77kw battery) is it worth switching to an EV tariff?

Thanks in advance for your wisdom!
Also as a new EV owner anything else I should be aware of :P?
