Zwave vs. Wemo Switches

Our home has a detached garage. It is only a few meters from the house, but I thought it might present difficulties for the wireless “smart switches”.

Zwave Light Switch:

My first effort was with an “Evolve Zwave Switch” to control the interior lights of the garage. The Zwave device is paired directly with the Micasa Vera (Zwave does have the benefit of creating its own network, with devices relaying commands to each other).

The garage is just at the edge of its effective range (and with no other Zwave devices just yet there’s nothing to help boost the signal in between the controller and the switch).

The Micasa Vera log shows multiple attempts to contact the switch before registering success. In practice I have it set up to automatically turn the lights on when the garage door opens, and then to turn them off again when it closes, and there is not noticeable delay.

Belkin Wemo Switch:

The Belkin Wemo switch relies on the Wifi signal from your home router. Setup requires you to use your smartphone to connect to a wifi signal generated by the switch, you then provide the app with a password for your home wifi and it connects directly to your router.

I attempted to install a Wemo switch almost immediately beside the Zwave switch mentioned above (same distance to router etc) in the garage and this was a total failure.

The Belkin Wemo switch was simply unable to consistently connect to the router, and would not complete it’s setup. I disconnected the switch and used it in a different location within the house.

Conclusion:

I like the Wemo switches because they can be operated throught the Wemo app if there is a problem with the Micasa Vera Controller. This kind of failure of the Micasa renders the zwave devices effectively inert.

I am impressed with the range of the Zwave switch, and will be adding a few more devices (door lock, thermostat, switch) to see if this improves the connection to the garage. Zwave also offers a wide selection of devices including three way switches, dimmers, relays – the list is endless) where Wemo is limited to single switches and individual appliance outlets.

For now, it’s 80% Wemo and 20% Zwave, but those numbers should balance out in a bit.

    Yes I have read a lot about the WeMo switches and a majority of users is complaining about the WiFi. This fact currently keeps me from buying it, but I might just install some WiFi Repeaters to extend the range, because controlling all these fancy gadget from the iPhone is definitely something I want for my future smart home :) Keep up the nice articles on home automation!
