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
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
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
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.
ethermometer and ethermometer RHT products do support
SNMP, and HTTP/web browser for collection/review of temperature (or
and humidity) data. These
not affected by the email limitations of the device.
are currently developing the next generation of the
ethermometer, on new hardware – which will fully support secured email
expect to have the new
product ready to ship in 2015.
