How to Monitor Web-Based Sensor Data
Using the Web Sensor Monitor
This tool helps you extract specific sensor readings (like temperature, humidity, pressure, status) displayed on a website or web page and send them to a Meshtastic node. It's great for monitoring publicly accessible IoT device dashboards or weather station pages.
Step 1: Enter the Web Page URL
Enter the full web address (URL) of the page showing the sensor data you want to track. Click "Fetch Content" to analyze the page's text elements.
Step 2: Select the Sensor Value Block
Look through the extracted text snippets presented below. Use the "Filter Blocks" input to search for specific text within the blocks. Find and select the block that contains the exact sensor value you need (e.g., just the number "23.5" for temperature). The system will highlight your choice.
Step 3: Configure and Send
Give your sensor reading a clear label (e.g., "Outdoor Temp", "Device Status", "Tank Level") in the 'Sensor Label (Prefix)' field. This label will appear before the value in the message. Specify the destination Meshtastic node ID and optionally change the channel. Click "Send to Node".
After Sending: Scheduling Regular Checks
After successfully sending a value, a "Create Task" button will appear in the success confirmation. Click this to set up a schedule (e.g., run once later, daily, weekly) to automatically fetch and send this sensor value at regular intervals.
Example Uses:
- Weather Monitoring: Extract temperature/humidity from a public weather station page.
- Device Status: Track the status ("Online", "Offline", "Error") of an online device shown on a simple status page or dashboard.
- Environmental Sensors: Get readings from environmental sensors (CO2, air quality) displayed on a web interface.
- Resource Monitoring: Check water tank levels or energy consumption data from a web-based monitoring system.
