I want to turn a light on and off from the Cayenne app on my phone and be able to press a momentary switch in that room to do the same thing.The momentary switch has to latch to keep the light on too. So if I turn the light on at the momentary switch in the room and say I leave my house and forgot to turn the light off I can just turn if off using the app. I want to be able to toggle the light on and off, between the app and momentary switch.
It’s definitely possible. Is the light a light built in to the ceiling, or a lamp that plugs in to the wall?
yes and i have an fan too
can u please tell me how it can be done
Here are some projects to get you started:
High voltage is being used, I know little about electrical work so I urge you make sure that you double check and don’t use this as a manual.
I work evenings and have to stumble trough a garage on my way in to the house. Got tired of almost falling over using my phone for light.
I hooked my Raspberry pi 3 with up a motion sensor (HC-SR501) and a relay to turn on and off a light.
From the motion sensor before the signal is going back to the raspber…

When I return to my home I make ever a cup of tea, And when I go to my home I do not see the key of my door, because there isn’t light.
I’m really determined to remedy the situation!
I will use a Raspberry Pi Zero, connected to the internet, and a Cayenne app for Smartphone an Tablet. I will connect the Raspberry Pi to the relay shield, and to the PIR sensor. When the PIR sensor read the presence of a person out of my door, Cayenne s…
About This Project
Over a number of years, I have been tinkering with my raspberry pi on and off not relay crating anything that had any real-world application.
But like most blokes when a problem comes along not just happy with a simple switch to turn on a light or buy a better control for the boiler,
so I decided the humble raspberry pi was the way forward so for a few years I’ve been renewing all my home wiring getting it up to scratch and bringing all the lighting back to one location wit…
You can also go the route of a pre-built power strip and just send a high/low signal to it:
I have the power strip above, I’ll see if I can find some time tonight to get it working.
these projects are for raspberry pi I would like the above for arduino
www.plc.us they have a plcduino that’s mega based with an esp8266 for $89. I’m quite impressed with mine and others are helping with coding it.
Amazon has switched electrical modules that have 4 independent high voltage outputs that may be the safest way to go. Kind of like having an electrical node.
I’ve done something like this:
IoT-cloud Globe Light: My kids don't like to go to bed in complete darkness. So, a while ago, we bought globe light, which isn't very bright, but it makes room lit enough so kids aren't scared of shapes and shadows.
That globe isn't on through the...
It has momentary switch, although not latching, and it is also controlled via Cayenne. I admit I haven’t tried with latching button, but I guess it can be done, a bit more complicated than my project, though still easily.
I hope this helps.
