Possible to turn off WeatherHat display?

I’ve built a weather station using the Weatherhat and remote sensors. It all works great but the ultimate goal is to install this remotely using LoRa and using solar power. Since the screen will not be used is it possible to turn it off and save the power?

I don’t think you can turn it completely off, as in unpowered.
You can minimize the power it uses by setting it all black.
Something like this.

img = Image.new('RGB', (WIDTH, HEIGHT), color=(0, 0, 0))
draw = ImageDraw.Draw(img)

and setting the backlight off
