I've revised the layout of what shows up on the display screen. I'm still tinkering with it. Besides fiddling with color combinations, I'm trying to decide what's best for someone either working in the garage or just walking past the controller. Here's a nice picture. The screen is slightly cloudy because it still has the protective film on it.

• In the top left and right corners are sensor readings (green) from the BME280 (except for the word "garag", which is the device's esphome node name (blue)). It's relative humidity, temperature in both C and F, and air pressure (I guess it's actually station pressure) in both hectopascals and inches of mercury.
• The yellow "6:37" in the top center is a countdown timer. It's the minutes and seconds until the lights will turn themselves off in the absence of motion detection or the use of any of the controls. When it gets down to 30 seconds, it changes to red and starts blinking. If there is any activity, the count resets and starts counting down again.
• The large white "18:14" in the center is a time-of-day clock with hours and minutes. The ":" blinks, and I happened to take this photo when it was blinked off.
• The section along the bottom gives the state of the dimmer control. It uses a graphical thermometer control (red on green) as well as a text overlay (cyan).
