The wireless temperature logger monitors the temperature and transmits these readings back to an Ethernet base station which then uploads this data to the cloud based server.
It provides two key benefits to the user:
Each point to be monitored (e.g. fridge, freezer, incubator, room) requires a wireless temperature logger.
At least one Ethernet base station is also required.
The unit uses the 433MHz range. The exact frequency can be modified but typically does not need to be adjusted.
This is a public frequency and is used by other devices such as portable phones and door bells.
The loggers will communicate up to 200m “line of sight”. In reality it will communicate up to about 2 rooms away, or across a warehouse. Doors and walls reduce the range.
The Ethernet base station uses 10Base-T and uses two ports to communicate with the cloud server. Port 80 (HTTP) and 6667 are required for external communication.
DHCP is used to acquire the IP address.
At the time of writing the server addresses were 220.127.116.11 (wirelesstag.net) and 18.104.22.168.
The Ethernet base station has minimal processing capacity and mainly relays information to and from the cloud server to the loggers. There is no configuration within the device required or possible.
Bandwidth is minimal.
Periodic updates of the temperature are very small in size and only occur every couple of minutes.
No. This is an Ethernet only product.
We use products like the Netgear AC750 Wi-Fi range extender to create an Ethernet port if there is only Wi-Fi is available.
No. The Ethernet tag manager is not based on an operating system or open source code. It does not have the security risks relating to them.
Error light. Flashes when trying to configure itself to connect to the Internet (when acquiring IP address through DHCP). Rapidly flashes when trying to connect to web service.
Connected light. Lights up when connected to the cloud based web service.
Update light. Flashes when forwarding a Wireless Sensor Tag reading to the web service.
Login light. Lights up when connection is temporarily interrupted (when trying to re-connect to the web service)
Radio light. Gradually ramps up and down when radio is ready to receive sensor tag readings. Becomes solid when radio is transmitting a command to Wireless sensor tags.
Not everyone is good with computers. And that’s OK.
If you’re stuck on something to do with one of our products, we’re here to help.
But can we suggest a product that will make things easier for both of us?
TeamViewer lets us securely log into your computer so that we can see exactly what you’re seeing.
And we can set things up for you while you watch so you can learn how to do it next time.
Once we’re finished, we log out and can’t log in again without your permission.
Best of all, Teamviewer is free.
