I have two separate main lines running to two separate valve boxes and will therefore require two flow sensors to monitor the overall flow of water. I also have a rain/freeze sensor installed, so I cannot wire the two flow sensors to separate sensor slots. Can I connect the two flow sensors to the same sensor slot on the Gen 2 Rachio controller?
I know there may be a slight increase in the inaccuracy of the flow sensors reading since one sensor's last "click" and the second sensor's first "click" will not line up on an even measurement boundary. The wires to the two sensors are shielded twisted-pairs, and should have minimal interference. Since only one valve will be running at a time, only one sensor should be sending "clicks" at one time.
I cannot see any logical reason why this would not work except for a possible power issue. From reading other posts, I don't think this would be an issue since I don't have a master valve or a pump that would be drawing additional power. Is there anything that I may be missing? Thanks.
