Setting Up Live Environment Monitoring

Connect your sensors to Meridian and get real-time temperature, humidity, VPD, and CO2 data streamed directly to your grow space.

Supported devices

Meridian currently supports:

• Govee WiFi sensors — temperature and humidity sensors that connect via Govee's cloud API. You'll need a Govee account and an API key.
• Ecowitt weather stations — stations that push data via webhook. Supports a wide range of indoor/outdoor sensors.
• AC Infinity controllers — WiFi-enabled controllers (69 series: Pro, Pro+, AI+). Coming soon.

How to connect a device

1. Go to your Grow Space page
2. Tap the Connections tab
3. Tap Add Connection
4. Select your device provider from the list
5. Follow the setup wizard

The wizard walks you through each step specific to your device type — including how to find your API key (Govee) or configure webhook URLs (Ecowitt).

Govee setup details

You'll need a Govee API key:

1. Open the Govee Home app
2. Go to Profile → About Us → Apply for API Key
3. Enter your name and the reason ("home automation")
4. The key arrives by email within minutes
5. Enter it in Meridian's setup wizard

Ecowitt setup details

Ecowitt stations push data to a webhook URL:

1. Open the Ecowitt app or WS View Plus app
2. Go to Weather Services → Customized
3. Enter the webhook URL shown in Meridian's setup wizard
4. Set the upload interval (60 seconds recommended)

What you'll see

Once connected, your grow space page shows:

Live readings — current temperature (F and C), humidity, VPD, CO2, fan speed, and light level (depending on what your sensor reports). Readings refresh every 30 seconds.

Freshness indicator — shows whether data is Live (green, updated in the last 2 minutes), Stale (yellow, 2-10 minutes old), or Offline (red, no recent data).

24-hour history chart — toggle between temperature, humidity, VPD, CO2, and fan metrics. Select time ranges from 6 hours to 7 days. Summary stats (min, max, average) appear below the chart.

AI integration

When you have a sensor connected and select that plant in AI chat, the AI automatically sees your recent environment data. It can tell you:

• Whether your VPD is in range for your growth stage
• If a temperature spike overnight might be causing stress
• How your humidity trend correlates with the issue you're asking about

This is one of the most powerful features in Meridian — the AI doesn't guess about your environment, it knows.

Troubleshooting

Connection shows "Offline"

• Check that your sensor is powered on and connected to WiFi
• Verify your API key hasn't expired (Govee)
• Check that your webhook URL is correct (Ecowitt)

Readings seem wrong

• Verify the sensor's placement — avoid direct light on the sensor, keep away from heat sources
• Compare with a known-good thermometer to rule out sensor issues

Connection shows "Error"

• Check the connection detail page for the specific error message
• The provider's API may be temporarily down — wait a few minutes and check again

Privacy and security

Your sensor credentials are stored securely and are never visible in the app interface. Meridian only reads data from your devices — we never send commands to your equipment or change any settings.
