    I am in Ottawa, Canada, so not sure if the country is causing a lookup problem. My baseline is 2.82mm (0.111 inches) and has not been hot or dry here. Just barely getting into the 70s during the day and mid 40s at night.

    I am a coder so if you can point me to the code I can take a peek on how it is working and may have some ideas.

    Also, not sure if you are interested, but this was my previous version. Back when I wrote it, nobody published daily ET or even solar radiation so I had to compute it based on historical cloud cover and math. Maybe that has changed in the last 4 years.

    That explains a lot, I think! Thanks

    But I am still confused since after my watering level at 187% this morning, and watering for 4 hours, the watering level is still at 187%. I would have expected it to go down due to the watering? I think I am still missing something about the baseline I think since it was not nearly hot enough today to warrant another 200% watering level.

    I think what you are / I am looking for is a threshold watering level (don’t bother watering if level is below 90%) and then it would accumulate for a few days until over that threshold. Would keep it from running every day?

    When I do a “baseline detect”, is that a baseline for my location that should not really change day to day? Or is that a computed baseline on a daily / hourly basis?
