====0x55 00FF 2A 55 Meter Data====
The data below was captured from the same meter (F0EE36DB) and shows some of the values that can change with each transmission. Different meters have different fixed data and some of the data changes less frequently as well.

====0xD5 00FF 2A D5 Meter Data====
There appear to be multiple packet lengths and styles for the 0xD5 packet. Some samples shown below, [https://wiki.recessim.com/w/images/9/9e/D5-Packets-Table-F03B9FFB.txt download as a txt file].

You will see 0xD5 packets in the data file closely linked to the times above. When the request is made on the website the meter generally responds within 10-15 seconds meaning the system can send a message to the mesh network, traverse across the meters and return fairly quickly.
