Thanks!
Of course you can.
I have made a dashboard for the staff earlier. This is on an iPad. They can control the whole gym from there, see checked-in members, control gates, check the cleaning list, etc. There’s also one page for the Signage display on which they can change the ‘storing’ message and select who is working (for the visible trainers on screen).
Everything is dynamic, with sensors for wellness, shop and temperature. The trainers are made with virtual devices (active / not active), and when a specific device is turned on, a Homey script puts it in one of the four slots (each a variable) and a url is called on the dashboard to show the trainer. The Homey script makes sure the slots are always filled from left to right and changes the visibility variable based on the variable of the name (nothing or a name).
The lessons are a self made connection to Virtuagym (our back-end system). The API gives me information about names, times, available spots for members, etc. The API script runs on Railway, Railway sends Homey all information via a webhook and a Homey script changes the variables based on the webhook input. These variables I put on the dashboard on self selected positions. The Homey script also rotates lessons every 20 seconds when they start at the same time and it makes sure that a live lesson is moved to the large window when it starts (or 60 min before start when there’s no live lesson now), which shows the next lesson below. Also the check-ins are coming from the API script and are used to fill a variable for ‘live drukte’ and live check-ins on the staff dashboard.
The visibility function is used a lot here. All descriptions and some other elements for lessons are already on the dashboard but only one shows, depending on the name of the lesson (in a variable), which triggers the visibility boolean of the description. The name of the lesson also triggers the image url of that lesson.
The green header is also dynamic, with names of members showing up when it’s their birthday or welcoming new members. Next up is a full screen overlay for events / deals, which shows every few minutes or something (also just based on visibility and a boolean). Members love it until now, it just makes the gym a little more premium for them. And yes, if I’d let myself go the dashboard would be full of cool things haha. But I have learned in the last years that less is indeed more. Not everything needs to be automated even if it’s cool, not does it offer anyone else but myself some satisfaction to see it. 
I am in no way a technical person, nor do I have such an education, but I love doing this.
I have been working with Homey for over 8 years now and have a fully automated home, with a dynamic floor plan made with HA (wayyy too much work but cool). It’s just fun and with the help of the community and a little AI, everything is possible.
And next to the fact that I own a gym, I have also been the owner of FWD.nl for 15 years, on which I wrote many times about home automation and it gives me the opportunity to test a lot of automation products.
