It is a UK version and I use the Smart Weather station App that fully supports the Tempest. I’ve not used every trigger but there is a fair selection available, see screen shot below:
All my daily Hue lighting is triggered by outside Lux rather than sunrise/sunset, and curtains/blinds which makes it much more accurate. Alexa announces if raining and garage left open etc. Ice warnings given when getting up in morning if below zero, garage door closes if left open and high winds plus a few other bits and pieces. All works well, weather station is rock solid, never needs rebooting and if you do have any questions the guys out in America are very helpful.
Agreed, the app not been updated for a while but I’ve not had any issues so far and been using this for a long time and proves useful as the trigger or input for many flows.
Cheers
