Tiny House temperature monitoring using Node-RED and LoRa
Overview
- In this lesson - temperature and humidity data from a Tiny House was collected using a Pycom LoPy4 and transmitted to a local LoRa WAN Gateway
- The data was processed in The Things Network
- The data was subscribed to using MQTT using Node-RED
- A time stamp was added simple time node
- The data was processed using a process node to extract out temperature data
- The data was then packaged so that it cold be dweeted.
- The data will be available to students as a Dweet so that they can monitor the performance of their tiny house
- Students will use Python to process the dweeted data (Dweepy module)
Node-RED Configuration
mqqt-in Node
mqqt-in edit Node - Connection
- Follow the example below to configure the connection to the MQQT broker on The Things Network
mqqt-in edit Node - Security
- Follow the example below for the security configuration.
- Note that the username is whi-tinyhouse-12-temperature-pycom@ttn
- Whereas the password is a very long chanracter set (40+ characters) obtained from the The Things Network Application page.
- For security reasons, Node-RED will not retain any passwords if the node is copied.
