This article is intended for IT and network administrators preparing a network for Cobra Climate sensors.
WiFi
- The sensor needs a secure WPA WiFi connection to function.
- We recommend a separate "IoT" SSID connected to a dedicated (virtual) network.
- WiFi band: 2.4 GHz, 802.11 b/g/n (802.11n up to 150 Mbps).
- Frequency range: 2412–2484 MHz.
IP addressing
- One IP address is needed per sensor. DHCP is preferred.
Outbound connectivity (sensor → platform)
- The sensor communicates with the platform only over secure MQTT (SMQTT) on port 8883/TCP.
- Data usage is very low: approximately 1–3 kB per sensor per hour, with bandwidth below 1 kB/s per sensor.
Dashboard access (user → platform)
- End users reach the Cobradash frontend over port 443 (SSL/HTTPS).
Whitelisting
If your firewall restricts outbound traffic, whitelist the following:
| Service | Address | IP | Port |
|---|---|---|---|
| Frontend (dashboard) | https://platform.cobradash.com/ | XXXX | 443 |
| Message server (MQTT) | https://mqtt.cobradash.com/ | XXXX | 8883 |
Note: Server IP addresses can change. If you are configuring strict firewall rules, please confirm the current addresses with Cobra Climate before going live.
