In case (b) the pedestrian gate doesn't need to be very reliable, and doesn't need to be fail open in case of fire (true?, do people still remember the code), since the padlock can serve as a fallback. In case (a) the solution needs to be very reliable, and be usable in case of fire (fail open, or mechanically openable from the inside).

One way might be to use a fail-safe lock (stays closed if power fails) but have a local battery backup for fire safety / to be able to reliably leave the space. Also possibly the yard is big enough to be able to stay far enough from a burning building to be safe? Will there be a fire safety inspection, and could we ask them for an answer beforehand?

One idea is to use WiFi, to save on effort and cost for the Ethernet cable.

People who voiced preference for cable for (expected) increase of reliability: (but at the time pre-7 is unclear)
