TaHoma switch

Two variants, one product name. The European unit (1870600 in the UK, 1870594 and 1870595 elsewhere) carries io-homecontrol, RTS, and Zigbee 3.0, pairs up to 200 devices, and uses Zigbee for lighting only. The North American unit (1871037) has no io-homecontrol at all, because io is not sold there: it drives 60 Somfy Zigbee products and 40 RTS channels, and up to ten switches can be joined for multi-zone RTS. Connection is Wi-Fi, with Ethernet through the TaHoma switch Ethernet adaptor, which is bundled in some North American kits and is the connection to use when the hub sits in a rack. For Home Assistant, enable developer mode in the TaHoma app under Account, Configure the installation, Access the parameters of your TaHoma box, then tap the PIN seven times; the integration then connects to the gateway PIN plus `.local:8443` with a token instead of going through the cloud. Two caveats on that local path: scenarios and climate entities are only available over the cloud API, and the gateway holds an execution queue of roughly ten commands. The integration batches commands sent close together, which keeps ordinary automations inside that limit, but a scene that moves every cover in the house at once can still overrun it and come back as an `EXEC_QUEUE_FULL` error, so stagger the big ones. Zigbee, Z-Wave, Hue, and Sonos devices paired to the hub are not exposed to Home Assistant even though the hub itself controls them.
