The PAC Node just points to the digital output. The Wemo node is simply configured for a payload of 0 when off and 1 when on. So, here is how it looks in my Node-RED web dashboard. This means that its pretty quick, and it means that you don’t have a major pile of security / https / applications / skills to jump through to get going. No phoning out to the cloud just to turn a switch on or off. Secondly, it means that everything stays inside your network. This is important for two reasons, firstly, it means that this flow only works on digital outputs. There is a Node that emulates a Belkin Wemo. In the kitchen we have computer that always has a Chrome browser running, so you just hit the button the way through to the garage. It simply turns power on and off to the light just like a light switch.įor the longest time, I have been using groov as the only way of flipping the digital point state. On the Opto end, I simply have a 120AC plug and socket with a break in the active line that goes to a SNAP-OMR6-C mechanical relay module. Since they are free standing, I have a longish extension cord that they plug into. When they are not in use, they hook on some chain hanging from my garage roof. I have a free standing bank of 6 fluorescent tubes to use as a work light. Had a bit of fun over the weekend… Got my Amazon Echo controlling a digital output on my garage rack of Opto 22 I/O.įirst the hardware.
