Pairing and communicating with
Asema E

2.4. Resetting the meter
Each Asema M series device has a dedicated reset button for removing pairing data from the meter
itself manually.
You should always try to reset the meter from the Asema E first before doing
a manual reset.
A manual reset will simply remove the pairing from the meter without telling about this to an
Asema E. It will therefore result in a "ghost" meter on the Asema E that can no longer be reached.
You can however remove it from the Advanced settings of the meter on Asema E. Please refer
to Asema E manual for more information.
The manual reset is needed if you have lost pairing data on your Asema E due to replaced equip-
ment, accidental deletion or other similar reason. To perform the manual reset, you must have the
meter connected to mains power. Then simply press the reset button.
You can find the reset button as follows
• On an Asema M1, the reset button is the transparent button with blinking red LED light
• On an Asema M2, the reset button is the gray button in front, marked with "RESET"
2.5. Mesh networking
Mesh networking means that Asema controllers and meters with a radio can relay messages auto-
matically between them and this way extend the range of communication or go around obstacles.
Thus they work automatically as repeaters of messages for each other. Asema S series controllers
and Asema M series meters will automatically form a mesh network when they detect each other.
Mesh networking is automatic, you do not have to do anything to enable mesh networking, the
devices will do this automatically. However, you may benefit from knowing the topology of the
mesh network as placing a controller between the Asema E and an Asema M meter that have
trouble communicating with each other may improve the situation.
To get most out of mesh networking, test the connection to the meter with the "Test" button.
If you get poor radio coverage (high packet loss or low radio quality) this means that the radio
is suffering from disturbance due to distance or obstacles. Placing a controller in a location that
is between the two devices, possibly so that it allows to bypass an obstacle, will improve your
installation.
