Changes

* 0x55 appears to be broadcasts from the meters and happen frequently. They have been observed multiple times per minute from a single meter.

* 0xD5 appears to be a packet for transporting data across the mesh network. Each D5 packet will contain two meter ID's, Meter ID #1 and Meter ID #2. There are many 0xD5 packet length and types that have been observed, some are shown below.

---- ==== 0x55 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. <code>1) Header = 0x00FF2A</code>  <code>2) Packet Type = 0x55</code>  <code>3) Packet Length = 0x0023</code>  <code>4) Unknown Identifier #1 = 0x30</code>  <code>5) Unknown Empty Data Slot = FFFFFFFFFFFF</code>  <code>6) Unknown Identifier #2 = 0x50</code>  <code>7) Unknown Identifier #3 = CF8DD9E2 (Appears to either be location identifier or duplicate meter ID in some cases)</code>  <code>7) Unknown Identifier #4 = C0</code> <code>8) Unknown Data #1 = '''02''' (Increments some amount with each transmission and rolls over at 0xFF)</code>  <code>9) Uptime = 0x'''0001ECA3''' (Value in seconds since meter powered on, easy way to see last time there was an outage!)</code>  <code>10) Unknown Identifier #5 = 0xA483</code>  <code>11) Meter ID = 0xF0EE36DB</code>  <code>12) Unknown Identifier #6 = 0x0100</code>  <code>13) Unknown Data #2 = 0x2132<br /code> <code>13) Unknown Data #3 = 0x'''042D19'''</code>  <code>14) Unknown Identifier #7 = 0x7E80</code>  <code>15) Checksum = 0xF154 04</code>  <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''0C''' '''0001ECBF''' A483 F0EE36DB 0100 2132 '''04384F''' 7E80 0896 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''16''' '''0001ECC6''' A483 F0EE36DB 0100 2132 '''043AC5''' 7E80 F47E 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''2A''' '''0001ED05''' A483 F0EE36DB 0100 2132 '''041207''' 7E80 A412 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''34''' '''0001ED29''' A483 F0EE36DB 0100 2132 '''041FF9''' 7E80 D9C4 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''38''' '''0001ED37''' A483 F0EE36DB 0100 2132 '''042571''' 7E80 963C 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''42''' '''0001ED5C''' A483 F0EE36DB 0100 2132 '''0433A9''' 7E80 8384 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''4C''' '''0001ED60''' A483 F0EE36DB 0100 2132 '''04354D''' 7E80 2CB6 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''4E''' '''0001ED79''' A483 F0EE36DB 0100 2132 '''043F25''' 7E80 871A 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''60''' '''0001EDA6''' A483 F0EE36DB 0100 2132 '''040F05''' 7E80 25C9 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''6A''' '''0001EDCD''' A483 F0EE36DB 0100 2132 '''041E55''' 7E80 F33F 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''74''' '''0001EDE7''' A483 F0EE36DB 0100 2132 '''042873''' 7E80 B091 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''76''' '''0001EDF6''' A483 F0EE36DB 0100 2132 '''042E31''' 7E80 048D 04</code> <code>00FF2A 55 0023 30 FFFFFFFFFFFF 50 CF8DD9E2 C0 '''80''' '''0001EE02''' A483 F0EE36DB 0100 2132 '''04331D''' 7E80 5271 04</code>---- ====0xD5 Meter Data====There appear to be multiple packet lengths and styles for the 0xD5 packet.
