I use mine all the time for turning things on and off but mostly for checking status of garage doors front door locks etc makes it super simple to check if things are closed or locked
I use my dashboards primarily for debugging and handling exceptions. I have one wall-mounted dashboard by the garage door that I use to see the status of the vehicle charging and the garage vs outside temperature at times.
Typically, I will automate re-occurring exceptions, so I often will eliminate the need for a dashboard.
I'm not surprised at how many responses this has gotten
I'll just echo some of what's already been said.. what I use my 2 wall mounted dashboards (Fire 10" and 7" tablets.. $35 and $15 respectively)
I use them primarily:
see at a glance if any of our doors are unlocked or left open when I go to bed at night
any garage doors left open
any lights left on
weather (current temp, future temps for the week, radar)
family calendar (I've got several calendars integrated into a single family calendar dashboard tile)
bring up security cameras (I don't do this often but it's nice to have)
I don't use them to enable/disable security.. that's all automated when my phone leaves the house
I also don't use them (too often) to turn on/off lights.. I've got Google Home mini devices on every floor so that's easy enough to do by voice. Sometimes I'll use them to lock a door but that's about it when it comes to controlling devices.
So, high-level a dashboard for me is a quick status of all of the smart devices as well as weather and calendar stuff.
I have a dashboard on my phone to get an overview/summary of all automations, including current energy consumption, which room/devices are active, and family whereabout all on one screen.
There are a few devices which are not on timers or switches, and to turn them on/off I go to the "Lights/Switches" page in the v1 mobile app. (I haven't even looked at the new app and won't until I am forced to switch.)
I should set up one dashboard for these buried devices, but I have tried out the old and new EZ dashboards and don't like either of them for different reasons. ¯\_(ツ)_/¯
Echoing others... Everything is automated, so I mainly use my dashboard for a quick view of what's going on. It only shows a small selection of all my devices. Are doors locked? Garage open? What's the weather? When will the sprinklers run? What's my wife's commute like?
I'm another who basically just uses a dashboard as an at-a-glance status check. If I asked a voice assistant to read off everything, it'd take 15 minutes and if I just set alerts letting me know when something was amiss, I wouldn't necessarily know if something was reporting that there was no concerning information or just not reporting at all. I can look at this and get a good picture of my home's status in a couple seconds.
For me it's all part of the fun and challenge of owning a Home Automation system. The three big ways to geek IMO out are automation, integration and visualization. All three are fun but I have a soft spot for the dashboard.
This is my ground floor. Visualization and control all in one place.
But other reasons are that they are accessible to people that don't know anything about Hubitat.
Clicking through devices and logs is a chore. Looking at tables of data easy.
