On the Tapo app with T310 Sensors and H100 Hub I am getting no monthly or yearly data on all 5 attached devices.  If I download the data I get only the row headings and no data.  I have tried every solution I could find on this forum but nothing works.  I have changed router DNS to 8.8.8.8 and 8.8.4.4 with No Luck.  I have Disabled IPv4 SPI firewall protection and IPv6 SPI firewall protection with No Luck.  I have unplugged and reset all 5 sensors and the hub numerous times.  I have even tried updating the firmware but all I get is my devices are using the latest firmware.

Signal Strength for each device is:

Bedroom         -63

Livingroom     -59

Spare room      -68

Printer room    -68

Outside           -90

What other solutions do you recommend?
