Visited on July 6 without charging.
It's not clear whether the chargers are open to all. 2 parking spaces are marked with the eCarUp green EV sign. The location on eCarUp has a picture (rare!) and roaming is enabled.
However it's inside the church parking and the sign at the entrance says it's forbidden to drive through or park inside except for church visitors, and there's no additional parking directive in the eCarUp description or next to the chargers.
