I installed an under the sink water filter than needs to have its filter changed every six months. I have a Homeseer dimmer switch on the counter above the sink that I am going to flash red on its status lights when it is time to change the filter.
In essence, I would have a quasi countdown timer. I have messed with a periodic trigger and also between two dates rule. How would the most efficient way be to accomplish the task? Also, how would I go about resetting the rule once the filter has been changed?
