I am about to install a Stenner pump for chlorine, and am looking for timer options that I can control remotely -- I generally bring a water sample in to the house at night and test it. I'd like to pull up an app and adjust the chlorine delivery for the next day without having to go back out to the pool. I also want to control a number of other outdoor and indoor lights with a Z-wave or similar mesh network.
However, the main issue is that I believe most of the Z-wave switches rely on at least the hub, if not the cloud server, for all switching events. If a switch is on, and the hub goes down for whatever reason (accidentally unplugged, for example), the switch will stay on past the intended time. This isn't the end of the world for a light, but obviously is a problem if a Stenner pump continues to push chlorine for hours, especially if the pump goes off.
I have a WiOn 50052 WiFi switch that I'm testing, which does appear to be a self-contained timer -- I experimented by unplugging the WiFi router, and the switch's status showed the connection failure but turned off correctly at the programmed time. I'd assume the other WiOn devices like the 50049 outdoor outlet work the same way. However, WiOn has some limitations as a broader home automation solution; it's just not as scalable or flexible as a hub-based system.
Has anyone found a Z-wave switch/hub combo that has similar protections, where the hub basically tells the device "tentatively turn on at time X, and turn off at time Y" and then overrides as necessary? I'm guessing not, but thought I'd ask if anyone has dealt with this. Otherwise, I think I'll just use WiOn for the Stenner pump and Z-wave for everything else.
