Radio Climate Monitor

This document will guide you through the Radio Climate Monitor project. You will be able to see dashboard with temperature, humidity, ambient light and atmospheric pressure in Node-RED.

Block Concept​

Block diagram: Radio Climate Monitor Kit linked over sub-GHz radio to the Radio Dongle and Node-RED gateway stack

Requirements ​

Firmware Upload​

In this procedure we will use the HARDWARIO Playground to upload firmware to the Core Module.

Step 1: Connect the Micro USB cable to the Core Module and your computer​

Step ****2: Run the HARDWARIO Playground. In the Firmware tab choose and upload the bcf-radio-climate-monitor firmware to the Core Module​

warning

Flashing Core Module R1 & R2 For differences of flashing older Core Module 1 and newer Core Module 2 please read Core Module R1 and R2 comparison in the Hardware section

Step 3: Remove the Micro USB cable from the Core Module and your computer​

success

At this point your firmware is successfully uploaded.

Hardware Assembling​

See short video with easy step by step demonstration:

Step 1: Start with the Mini Battery Module​

warning

Make sure the Mini Battery Module does not have batteries inserted.

Step 2: Plug the Core Module on top of the Mini Battery Module​

Step 3: Plug the Climate Module on top of the Core Module​

Playground Bootstrap​

danger

If you are using the new HARDWARIO Playground, then use the Functions tab instead of using http://localhost:1880/. Also the pairing process is now done in Devices tab. For communication test use the Messages tab.

Step 1: Open Node-RED in your web browser​

http://localhost:1880/

Step 2: You should see the empty workspace with Flow 1​

Step 3: Insert the following snippet in the flow (using Menu >> Import) and click in Flow 1 tab​

It will look like this:

Imported Node-RED flow with inject buttons for the gateway commands, each wired to an MQTT node

info

This snippet provides control buttons for gateway/radio commands. These commands are sent over the MQTT protocol.

Step 4: Deploy the flow using the Deploy button in the top-right corner​

Step 5: Open the debug tab​

Node-RED editor with the debug tab highlighted in the right sidebar

info

In the debug tab, you will be able to see all the MQTT messages.

Step 6: Click on the List all gateways button. You should see a response like this in the debug tab​

Debug tab showing the gateway info response after clicking List all gateways

success

At this point, you've got working Node-RED, MQTT, HARDWARIO Radio Dongleand HARDWARIO Gateway.

Radio Pairing​

In this section, we will create a radio link between the Radio Dongle and the Radio Climate Monitor.

Follow these steps in Node-RED:

Step 1: Click on the Start node pairing button​

Start node pairing button highlighted, with the pairing start confirmed in the debug tab

Step 2: Pair Climate Monitor​

Insert the batteries into the Radio Climate Monitor to send the pairing request (you should also see the red LED on the Core Module to be on for about 2 seconds).

Step 3: Click on the Stop node pairing button​

Stop node pairing button highlighted, with the pairing stop confirmed in the debug tab

success

At this point, you've got established a radio link between the node (Radio Climate Monitor) and the gateway (Radio Dongle).

Communication Test​

Follow these steps in Node-RED:

Step 1: Switch to debug tab on the right​

Step 2: Test connection​

Start breathing on the temperature sensor on the Climate Module to invoke a change of temperature and hence trigger a radio transmission.

You should then see similar messages:

Debug tab listing incoming MQTT messages with temperature, humidity and light readings

success

At this point, you've got verified radio communication.

Enclosure​

Optionally put the assembly into the appropriate enclosure, if you have one.

info

You can find more information about the enclosures in the document Enclosures.
