Introduction: Heating Control Using Raspberry Pi and Cayenne App

Picture of Heating Control Using Raspberry Pi and Cayenne App

This is the over view of my project that dose more then just the heating but I will try to explane the heating control side

Step 1: THE HARD WARE

Picture of THE HARD WARE

raspberry pi B as the many controller

two of the relays to control the switching of the boiler

4x 1wire DS18b20 temp sensors

and a conversion board to control the relays 5v logic with pin points to connect the sensors

Step 2: THE CAYENNE APP

Using my devices with cayenne app on my phone is easy to crate schedule's and trigger points for high or low temp and even monitor each zone ,

and using the online dash to over ride the relays is made easy.

Step 3: How It Works

with the cayenne app scheduler widget one of the relays will only switch between set times and with the trigger widget the second relay will only switch if the temp drops to the set trigger point.

So using the sensors in each room I can set individual low and high trigger points so if the temp drops in one the heating will switch on and if it gets too high in another it will switch off only between the set time.

and running the relays in series with both the schedule and trigger widget they both need to be switched before the heating comes on.

Once you download Cayenne can it run as a stand alone application running on the RPI that you can run without connection to the internet? I want to setup a dedicated IOT system without connection to some cloud or server on the internet, Not interested in looking at it from work.

Hi Deki
at the moment cayenne is cloud basted but from what I've read in the cayenne community posts it is on the road map.
but in saying that using cayenne as a cloud basted app works and it works well.
best thing I can say is CHECK IT OUT.

Cayenne looks interesting. I am going to have to check this out.

It's very interesting and very cool my friends with in a couple of minutes of install you can have a fully working project to be proud of.
