I had ordered 5 of the Hampton Bay Zigbee Fan Controllers from Home Depot and knowing they were about to arrive I got the HubConnect Fan stub driver written for it in hopes of getting it included in v1.4. [Hubitat now supports 'FanControl' which has specific enumerated speed settings vs using a Dimmer and that was my part of my purpose. Dimmers for fans continues to work.]
I have now installed 4 of the 5 Controllers, which by the way, doubles my Zigbee network, and I've got one of them downstairs, while Zigbee radio is exclusively an Upstairs radio. One of the automations I've been wanting to do for years, while waiting for a ZWave version of a Fan Controller and waiting... is to turn on a fan based on temperature of the room. The ZWave temperature sensor is attached to the Downstairs Hub. It will come as no surprise to everyone using HubConnect that I can build a Rule on the downstairs hub that is driving the fan paired to the upstairs hub.. Hub to Coordinator to Hub and it's as instant as the Rules driving the Upstairs fans, where temps and fans are all on one Hub.
It still makes me grin when this tech stuff works as I imagined it would/could.
