In Clever Logger we show you the signal strength in two ways:
- A general description where we break it down into 4 categories
- A percentage
In this article I will start with the 4 categories and what they mean. For most users this is what you need to know. I also include information on what the numbers are showing.
The categories of signal strength
There should be no problems at all with the logger communicating with the gateway.
Practically, we would guess that the logger is within about 6m, probably the same room, and not blocked.
You don’t have to do anything.
The percentage will be 60% to 100%. 60% is approximately 6m away from the gateway (line of sight), and 100% is where the logger is very close to the gateway.
The signal strength is still at a level that provides reliable communication with the server.
You probably don’t have to do anything.
The percentage goes from 12% up to 60%. We may move the lowest level a bit, but our current experience is showing that 12% is still a good number.
This is the point at which communication is happening, but it isn’t strong.
We would encourage you to try and improve the signal strength by:
- moving the gateway closer,
- moving the logger in the fridge closer to the front,
- not lie the logger on a metal shelf,
- ensure the gateway and logger aren’t surrounded by metal, water or ice
Now we really recommend that yo do something to improve the signal strength.
There is enough signal coming through for us to get an occasional update, but we can’t guarantee a quick two way communication.
There is a good chance that we won’t be able to retrieve the log from the device if it goes offline.
Investigate the options listed under “marginal”, and also consider:
- adding another gateway,
- using an external probe logger so the electronics are on the outside
- using WiFi so the gateway can be moved closer
