IoT Server

Dedicated platform for integrating sensors, devices and hardware/software experiences in an IoT context.

The IoT MQTT server of the Meshtastic PT community was designed as a technical alternative to the main network (LongFast), to support specific use cases related to the Internet of Things (IoT), such as:

  • 🔧 Integration tests between sensors and microcontrollers
  • 📡 Development and experimentation with Meshtastic radios
  • 🧪 Proof-of-concept environments, without interfering with the main network
  • 🔍 Exploration of new firmware, channels and security configurations

This server provides a dedicated and controlled environment for enthusiasts, researchers, developers and makers, allowing data collection and exchange without overloading the community infrastructure.

The focus is to ensure public network stability while fostering freedom to experiment in technical or academic contexts.

IoT Server Access (MQTT) Recommended
  • Server iot.meshtastic.pt
  • Username meshdev
  • Password large4cats

This server and the LongMod mode are dedicated to IoT-oriented devices and tech experiments. Ideal for those building sensors, custom gateways or experimental projects.

No. If you choose the LongModerate radio preset (or LongMod, when applicable) and the IoT MQTT server, you do not need to manually change Node Info or other advanced options.

No. LongFast and the IoT server are independent. If you want to follow LongFast messages without changing your configuration, you can join the Primary Telegram group for indirect reading.

Separating your sensor data from other devices protects data integrity and privacy. With an encrypted secondary channel, only devices with the same key can exchange information.

Go to Settings → Channels → Add Channel and configure:
  • Channel name (leave blank to keep the preset’s automatic name)
  • Encryption key
  • Type: Secondary
  • Enable: Allow position requests
  • MQTT Uplink & Downlink
Repeat the configuration on the devices that will share the same sensors.

You can access data locally via RF, or remotely via MQTT (through the IoT server). The integration is similar to LongFast.

Meshtastic software: yes. It may be used commercially, provided that the applicable licenses, including GPLv3 where applicable, and relevant laws are followed.

Name and logo: use of the Meshtastic® name and logo is subject to the Meshtastic LLC trademark guidelines and must not imply affiliation or endorsement.

Meshtastic Portugal IoT server: as a rule of this community service, community data may not be appropriated for commercial purposes, and the community may not be used as an advertising platform. This restriction applies to the Meshtastic Portugal service and its data; it is not a general prohibition on commercial use of Meshtastic software.

The 2.4GHz band is highly recommended: it has no duty cycle, can be used continuously and allows power up to 100mW (tx + antenna). Great for constant applications and urban environments.
