I’ve hit the same problem with my test install 🙁 I have just a FC80GT, FC80RC and a wireless switch. No HomeKit bridge. First I was unable to connect the Home+Control to the gateway – was giving the error to check if I’m not using a 5Ghz wifi, while my router has only 2.4Ghz. After a reset of the gateway I was finally able to get Home+Control working but HomeKit was completely not responding – the room names were there, but no accessories. If I change the room name in Home+Control the name changes was correctly propagated in HomeKit. When I opened the bridge in HomeKit it reported that the bridge is not responding. This makes the whole HomeKit app stall if you try to perform any action (for example add accessory).

Not the best first time experience and I was under the impression that the Legrand/BTIcino gateways were aiming for HomeKit certified label! One of the reasons why I chose to use them instead of any other protocol/bridge.

Hopefully this will get resolved soon or I might have to look at the possibility to write a HomeBridge plugin to work with the Netatmo’s API and get the whole installation work via HomeBridge.
