Thank you for your work on this great integration that I have used for a few months now 
I just updated to 3.0.24 today, and am glad to see the new sensor.wiser_lts_energy, it’s great to now get that information from the heating actuators!
I also tried to use the new network map feature, I followed the instructions in the Readme.Md, installed zigbee2mqtt-networkmap but sadly the map remains blank, and while troubleshooting this issue, I can’t find the entity sensor.wiser_zigbee_network_map. Is there something else I need to do? Add the sensor manually?
