Visited on Tuesday without charging.
The chargers are in front of the GraubündenVIVA building, there are no gates.
I think there used to be a store here? The building is currently empty and for sale/rental. I wonder what the sale contract says about the chargers!
The chargers seem to still be working. There's a credit card reader on the DC charger but it's off and not offered as an option on the screen.
The charger is a Terra 124 CC but Plug'n'roll only lists the CCS plugs at 60kW instead of the theoretical 120kW. I don't know whether there's a site limit, a hard-coded half split between the 2 plugs, or if this is just a conservative display value and it's possible to charge faster. My car wouldn't have been able to charge fast enough to test.
The sticker says the CCS cables are only 200A, so that's a theoretical max of 80kW at 400V. The charger is rated for 800V as well.
