Quest: I am looking for a remote Wifi-enabled switch or relay that switches 120 volt household power OFF via some type of remote Wifi connection, then back ON automatically by itself after 5 minutes or some preset delay. Any suggestions for a specific product or solution?
The Situation: I have a country cottage with a WiFi modem and router and several other devices connected for various home automation functions including cable modem, router, security lights, appliance switches, heat, bridges, security cameras, Logitech Harmony remote for TV and Sonos music and more. Normally, it all works very well, even remotely when I am away from the cottage using apps on my iPhone and Siri for some functions. Everything is powered and connected via one single wall outlet plug (15 amp circuit, 120 volts) and, from there, several other power bars with GFCI-type circuit breakers etc. And, FYI, I cannot get around using this one single plug at the start of the power sources, it's a small cottage but I do not think that by itself is a problem.
The Problem: The problem is that, sometimes, when I am away, a couple of these components lose their WiFi connection randomly (for some mysterious reason) and the simplest solution is to perform a whole system a "reset" to make everything work properly again. Please see "Additional Info below" for a more detailed explanation. I do not know why this happens exactly but it only happens, on average, say once a month at randomly different times but the solution is simple.
The Solution: The usual solution for any problem with my system is to simultaneously unplug the power to all the components, including the modem, wait 5 minutes for internet and other signals to power down completely, then restart everything all together so that a complete reboot of all the components automatically re-establishes all the required connections and everything starts to function normally again after a few more minutes. I do not know the reason why a few of my components drop their signal but that is not my question here.
Query: I would like to reboot my system remotely when I am away from the cottage. The problem with rebooting could be addressed by having a remotely enabled relay or switch (with appropriate amp and watt capability, so, not a light switch) which would be at the front end of the power supply to my system's source of 15 ampere, 120 volt power, i.e. a dedicated household wall power outlet. However, if I just disconnect the power remotely, I cannot remotely power it back ON since the modem and router would have no power.
Additional Info: The modem needs to be rebooted for this solution to work; rebooting of everything other than the modem (or the router) won't properly reset the system. However, interestingly enough, I don't think the modem or router is faulty (or their settings), it's some of the component bridges that sometimes fail and seem to be the problem, but a modem and router reset along with a reset of everything else, does fix the problem. More specifically, just for a complete understanding as I see it, the problem seems to have something to do with the interaction of the Harmony Remote bridge, the Lutron Casseta bridge and the Nest Thermostat WiFi connectivity.
That is why I am looking for a switch or relay that can power back on after a delay of 5 minutes or more. Any help or advice would be appreciated but please keep in mind that in this discussion I am really just looking for an appropriate switch or relay.
