![]() More importantly, while double tap worked OK in late 2014 and the beginning of 2015, around the summer of 2015 it started failing for almost everyone because cloud latency threw off the precision needed to meet the time window. First, there aren’t enough possible variations to give you low/medium/High/off for both fan and light. This doesn’t really map to the fan/light use case. The concept of double duty was originally that a smart app would capture two separate taps from a switch and because they were within a predefined time period would then initiate a different event than a single tap.It’s an interesting idea, but Double duty probably won’t work in this case for multiple reasons. In the image you posted I assume the larger item is the fan switch. Just thinking outloud because this topic has some of my wheels spinning on possible use.įor a follow-up question. In the US, they are in the mains-powered HMS1… In the UK, you will find this option in the battery powered Popp and Z devices. Much better precision, which is why many of these switches can also do a triple tap. Instead of trying to time the interval between two taps, they are sending a different code number from the switch to the hub based on whether the switch was single tap or double tap. The newer alternatives are Z wave switches which are using the Z wave “central scene” command set. What you put the cloud into that mix, it gets really hard to hit the target precisely. Previous switches did double tap by having the controller try to precisely time the interval between the taps. You might also consider a new alternative that just recently came on the market. You paid a lot for those switches, make them work Double Duty! Community Created SmartApps UPDATED - "Double Duty" - Use redundant switch presses to control other lights. Based on your answers also determine which device to use and then the priorities you put on each also affect your choices.Īnd finally here is a smartapp to control the ceiling fan based on temperature. Do you want to have local manual control of the light at the wall box?Įach of these options have pros and cons depending on the location of the neutral at the wall box or at the ceiling box.Do you want to have local manual control of the fan at the wall box?.Do you want 3-speed fan control or just simple On-Off to whatever speed I set via the pull chain?.Do you want to use incandescent, LED or CFL bulbs?.Do you want to have dimmable light control or simple On-Off control?.Then answer a couple of questions to determine your use case on how you want to use the system: If you post a picture of the box wiring it really will help us to help you if you are not sure. I use a non-contact voltage detector to help me determine what wiring I have. And check the same at the ceiling fan fixture wiring box. So please open up the wall switch box and see if you have incoming power on one of the romex (black from the breaker panel, and the white neutral) and then you have a second romex that goes up to your ceiling fan/light box. ![]()
