=== Sample Captured Meter Data Analysis===There have been two packet types observed thus far, a 0x55 and a 0xD5 packet. * 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 ====<br /> ==== 0xD5 Meter Data ====
<code>1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) 12)</code>
<code>4) Unknown Identifier #1 = 0x21</code>
<code>5) Meter ID #1 ID = F05FCB84</code>
<code>6) Meter ID #2 ID = F0FC4DB1</code>
<code>7) Unknown Identifier #2 = 0xE288</code>
<code>12) Trailing byte = 0x00</code>
