Make sure to look for Zooz blueprints - there are blueprints for many switches. The blueprint for the Zen32 scene controller really helped me use the switch to the full extent.
One of the features of my Tempest PWS that is a real blessing over the summer in lightning detection. My rescue beagle does not handle thunderstorms well, and the vet recommended some anti-anxiety meds - but they need to be given well before the storm is audible to some very large ears. So, I have a Home Assistant automation that sends alerts for > 5 strikes within 60 miles.
You can also get the Blitzortung integration for Home Assistant, which will let you generate an alert from their cloud data.
According to the Ioniq Guy on YouTube, Hyundai has just announced a service update that activates the brake lights based on deceleration rate. The update will be available in July, so a pretty quick response.
I hope they a) improve it, b) keep it platform-independent, c) maintain the paid subscription. I don't use it when driving, but it's the best I've found for planning.
For the Ioniq 5, the brake lights supposedly do turn on for the higher levels of regenerative braking per https://youtu.be/G1rJNNKRzqY . I wonder if the discrepancy between these two results is different software for the North American market?
Going to have to do a test on my iq5 when traffic calms down..
