What the latest status on Estimated Usage - can I disable it


As mentioned in some of my other posts, I have a autofill for my waterfall. Connected in series with the Rachio and the circuit valve is an electronic sensor that indicates the waterfall basin is full.

What I do is schedule Rachio to run this circuit for an hour when the waterfall is NOT running.

Lately I am seeing days when the system says estimated and it calculates usage for the entire hour period not the real amount that the flow sensor measure which can very greatly depending how how much the waterfall is usaed, and temperature/humidity causing increased evaporation.

As a result my entire water usage total is totally out of whack. Instead of taking 1 or 2 gallons to top off the waterfall, it is aggregating 312 gallons assuming the circuit is pumping water for the entire scheduled time.

What is the point of the this estimating and what are the conditions it happens? Is the server not available?
