The ET-2RHT Ethernet Hygrometer is a relative humidity & temperature monitoring device that monitors ambient or spot temperature and humidity, graphs the values on its self-contained graphing webserver, and emails or alerts you with SNMP if the values go outside the user-set high and low limits. The ethermometer Plus includes one temperature and humidity probe with two logic 'closure' inputs for monitoring dry contact closures from external devices or switches. The status of the closures is also viewable via webpage.

Configuration is super easy - the ethermometer supports DHCP so you just plug it in and the network configuration is automatic. Or you can manually program the IP address and other network particulars. Our Etherset utility allows you to enter the serial number of your device and retrieve (or set) the IP address so you can access the data and configuration webpages. The ethermometer also supports DNS lookup for the destination email server so you don't have to know the destination server's IP address to set up the email functions. Also new is SNMP (Simple Network Management Protocol) support for centralized monitoring. The ethermometer's temperature and closure status are continually available in standard format for your SNMP monitoring system.

The email capabilities of the ethermometer require access to and use of an SMTP server, knowledge of the SMTP server name or IP address, plus a valid destination email address. 

 *Important Notice regarding email functionality:

The Ethermometer and Ethermometer RHT use SMTP open relay to send email messages to your email server.  The embedded processor we used for these devices was not capable of supporting a standard email client (with authentication) implementation.  If you are using gmail, yahoo mail, or many other email ISPs, the ethermometer’s emails will be blocked by your email server.  Some providers allow for IP address-based pass through, but many do not.  If your organization has its own email server, you may be able to configure it to whitelist (and pass) email from the ethermometer.

 The ethermometer and ethermometer RHT products do support SNMP, and HTTP/web browser for collection/review of temperature (or temperature and humidity) data.  These functions are not affected by the email limitations of the device.

 We are currently developing the next generation of the ethermometer, on new hardware – which will fully support secured email client operation.  We expect to have the new product ready to ship in 2015.
