In the web app I just checked my watering history... I see this:
It says that I watered for 4166 minutes... if you've figured out how to get 70 hours in a day, I'd be interested in learning that trick! All of my bars show the same issue.
You are a light weight. I got 97.3 hours watering on June 15! But I am more impressed with the restraint the Iro showed on June 28 when it managed to spread 4 gallons of water out over 15 hours.
@Dan is looking into this.
