Poseidon2 3266: Remote sensor monitoring over LAN


Poseidon2 3266 is a basic device for remote reading (monitoring) of sensors over the network. It measures temperature, voltage, and states of dry contacts (digital inputs) and other external sensors. It sends e-mail alerts to values out of a specified range, or connects to an environment monitoring system. Supports M2M protocols – SNMP (SNMPv3), Modbus/TCP, XML, and the Sensdesk.com online portal.

Poseidon2 3266 monitors temperature and other sensors over a network in order to create a remote environment monitoring solution. Up to 8 sensors and 4 digital inputs (dry contacts) can be connected. Poseidon2 is connected to the LAN, reads measurements, and stores the measurements in its internal memory (data logger). The device is accessible via WEB and can send e-mails (or text messages).

Sensors and detectors
We supply humidity and temperature sensors in indoor or outdoor designs, light intensity sensors, DC or AC current and voltage converters. Other sensors include smoke detectors, power failure detectors, water flood detection, and more.

When a value is out of a specified range, Poseidon2 sends an e-mail, a SNMP Trap, or a text message (SMS).
No software is necessary to send text messages over the GSM network. All HW group devices can send text messages (SMS) through a single central gateway, the HWg-SMS-GW. Just a single SIM card can serve all your devices.

Poseidon2 3266 can be connected to various third-party applications or cloud services using various protocols (SNMP, Modbus/TCP, XML, HWg-Push).

Typical applications

  • Poseidon2 sends an e-mail if a temperature is too high or a door is open (a dry contact connected to a digital input is closed). It can also monitor power supply status, smoke detectors, and the environment.
  • Poseidon2 3266 is suitable as a remote monitoring system for servers and technology rooms. Measure remotely with Pt-100 and other temperature and humidity sensors.
  • A frequent application is a remote environment monitoring system.
    It is easy to connect smoke detectors, water leak detectors, PIR motion sensors, etc. They are powered from the Poseidon2 3266 unit.

>> Software and applications

Connection to the SensDesk.com online portal

  • Poseidon2 3266 can be connected to the SensDesk.com online portal.
  • All devices, sensors, values, history and charts can be viewed from anywhere over the web, or in a mobile app.
  • For programmers: Devices connected to the SensDesk.com can be monitored using a XML interface.

Text message (SMS) alerts

Alert SMS can be sent from the Poseidon2 3266 monitoring unit in several ways:

  • Directly over the network using SMS-GW
    A text message can be sent from the Poseidon2 3266 unit to a specified phone number using the HWg-SMS-GW unit.
    No software is needed. HWg-SMS-GW should be connected to the same LAN. Sender's phone number is defined by the SIM inserted in the HWg-SMS-GW unit. Recipient's phone number is configured in the Poseidon2 3266 unit, similarly to e-mail recipients.
    One HWg-SMS-GW gateway can be shared by several devices (e.g. Poseidon2 4002 in the picture).
  • With the HWg-Trigger application for Windows
    The HWg-Trigger application can run in the background on any PC with MS Windows. The application checks for device failures, disconnected sensors, or sensor readings outside of the Safe Range. Alarm status can be notified e.g. by sending a SMS to a specified number using a “HWg-SMS-GW” in the same LAN.
  • With third-party software applications
    Many SCADA (e.g. CapTemp) or SNMP (Nagios, Zabbix, ..) applications can monitor the status of Poseidon2 3266 units and send alerts via SMS.

Logging of values

  • Poseidon2 includes an internal flash memory for the data logger. Data are kept even if the power goes off.
  • The logger has a capacity for 250,000 records. For Poseidon2 3266 working as a temperature logger with one temperature sensor and 4x DI, this means enough memory for 230 days (7.5 months) when logging every 300 [s] (5 minutes).

Tip: The HWg-PDMS application can, for instance, read data from the internal memory over e-mail or web interface.

  • What is the maximum number of e-mail recipients for alerts?
    Poseidon2 itself can send e-mails to 5 e-mail addresses at the most.
    With the www.SensDesk.com online service or the HWg-Trigger application for Windows, e-mails alerting to OK/Alarm states can be sent to more than 5 e-mail addresses.
  • Poseidon2 3266 supports 8 sensors but features only two RJ11 connectors. How can I connect more sensors?
    Sensors can be daisy-chained, or connected to a hub: T-Box2 (photo), T-Box (photo) or 1-Wire hub Power.
  • How many temperature/humidity combo sensors can be connected?
    Poseidon2 3266 supports 8 sensors (quantities). Up to 4 combined temperature/humidity sensors can be connected.
  • What can I measure with Poseidon2 3266?
    Indoor/outdoor temperature and humidity, light intensity, 0-60V DC voltage, 0-30V AC current, 4-20mA current, Pt-100 and Pt-1000 external temperature probes, DI (digital inputs), analog PTC and NTC. For details see Overview of sensors.
  • Can Poseidon2 3266 measure energy consumption?
    Yes, it can measure the immediate current or voltage.
    To measure energy consumed over a time period, e.g. [kWh] or [J], we recommend to use the HWg-PWR 3/12/25 device and a M-Bus enabled electricity meter, gas meter, water meter or heat meter.
  • Why does the unit have the Power-Out?
    A typical application involves the use of an external smoke detector, motion sensor etc. These sensors feature a relay output that connects to IN1 – IN4. However, external detectors need power (typically 12VDC). The Power-Out terminal block is convenient for connecting a power adapter (jack) for powering the external detectors.
  • How can I create a graph or protocol with recorded temperatures?
    Use the HWg-PDMS software utility for Windows. Values recorded in the database can be displayed or exported to MS Excel.
    Or, use a suitable third-party software. For a list of over 50 third-party applications, see: Third-party software
  • Do you offer a SW solution that will alert me to an outage of a Poseidon2 unit?
    Yes, you can use the HWg-Trigger application that runs on any Windows PC.
    Another option is the www.SensDesk.com online service – free portal for IP sensors.
  • Is there an app for my mobile phone?
    Yes, several third-party apps for Android and Apple are available here: Android and iPhone mobile apps for HW group products
  • The humidity sensor reading oscillates around the specified SafeRange and I received over 50 e-mails in a single hour. What can be done about it?
    Set the hysteresis for this sensor to about 5% RH. This reduces the number of unnecessary alarm start/end e-mails that would be sent a couple of seconds one after another.
  • Will I lose data in the internal memory (log file) if the power is disconnected?
    No, stored data are protected against power failures. When the memory is full, the data logger overwrites oldest data with new data.
  • Can Poseidon2 3266 detect the presence of 230VAC (e.g. the input voltage of an UPS)?
    Yes, use the input voltage detection feature of the PowerEgg unit, or any relay with a contact connected to one of the IN1-IN4 “Dry Contact” inputs.
  • Poseidon2 3266 features 4 digital inputs for dry contacts (IN1-IN4). Is it possible to connect more digital inputs?
    Yes, use the Expander 4xDI 1W-UNI module – however, it counts as 4 sensors.
  • Can I connect Poseidon2 3266 to a cloud?
    Yes, Poseidon2 is a “cloud oriented sensor”. It can be connected to cloud systems, such as the “Cloud sensor”.
    Use the HTTP-based HWg-Push protocol. For more info, contact us.
  • Can I control relay outputs with Poseidon2 3266?
    No, Poseidon2 3266 does NOT have digital or relay outputs. Instead, use Poseidon2 3268, 3468, 4002 or Damocles products.
  • What is the warranty?
    The standard warranty is 2 years, can be extended upon request.
  • Where can I find the prices of your devices?
    Ask our distributors, or request a quote from us (by e-mail or by filling out this form).
