Visited yesterday without charging.
The parking is accessible without gate, but you need a valid P+R ticket to park. There is no payment machine, the ticket must be purchased in the SBB app, or I suppose it might also be available through one of the SBB sales offices.
The 2 spots on the right are indeed reserved for Mobility now. The Energie360° branding and QR codes are still on the charger, and the links actually still work! The payment page indicates 20ct/kWh, but I don't think anyone is supposed to use that.
The public chargers are still at 50ct/kWh, and there's an overstay fee after 12h.
