I previously had rules setup that below a certain PH, it would shut off my AC outlet that controlled my CO2 solenoid. Then I had a schedule that would turn it back on a few hours later. Recently, it shuts it off as the rule states. But once it turns back on, the rule does not run again and the solenoid outlet never shuts off, no matter if the PH gets lower than the set amount or not. Any ideas?
