====Sync and Header====
====Sync and Header====
----The sync word that the Landis+Gyr smart meters send is shown below, this can be used in GNU Radio or other tools to receive only packets transmitted by the meters. Note that at the start of the header we begin using start and stop bits. These must be stripped off of the rest of the data packet during processing.
----The Landis+Gyr Gridstream smart meters use a 52 bit sync shown below regardless of Gridstream version. This can be used in GNU Radio along with the header to uniquely identify packets. Note that at the start of the header we begin using start and stop bits. These must be stripped off of the rest of the data packet during processing.

----Of particular note is the difference between versions 1-4 and version 5. In version 5 there are two bits [11] that do not respect the start/stop bit checks of the prior versions. The older protocol expects a 0 start bit, 8 data bits and a 1 stop bit. By violating two consecutive start bits the older versions of GridStream ignore version 5 even if they have the same CRC Adder! This appears to be a way to add backwards compatibility to newer versions of GridStream.

Using GNU Radio it was found that shortening the Sync requirements a bit and incorporating part of the header leads to the cleanest data for further downstream processing. The modified sync shown in 8 bit chunks is shown below.
----Using GNU Radio it was found that shortening the Sync requirements a bit and incorporating part of the header leads to the cleanest data for further downstream processing. The modified sync in 8 bit chunks is shown below. These two sync's are both loaded into the '''PDU Align''' block and if either one is matched the full packet is passed downstream.

*Field 5 - Never observed a packet with this length and subtype that wasn't all FF's
*Field 5 - Never observed a packet with this length and subtype that wasn't all FF's


*Field 6 - Have only seen this change when comparing data from different energy providers
*Field 6 - WAN Address - Oncor uses GPS coordinates, CoServ uses LAN with padding of some kind.  The open source [https://github.com/beroset/gpsdecode gpsdecode] library shows one way to translate between WAN Address and GPS coordinates.
 
*Field 7 - Appears to either be location identifier (Oncor) or duplicate meter ID (Coserv)


*Field 9 - Increments some amount with each transmission and rolls over at 0xFF
*Field 7 - Increments some amount with each transmission and rolls over at 0xFF, always an even hex value


*Field 10 - Value in seconds since meter powered on, '''easy way to see last time the meter experienced a power outage.'''
*Field 8 - Value in seconds since meter powered on, '''easy way to see last time the meter experienced a power outage.'''
*Field 10 - LAN Address, Meter ID that's listed on the sticker on the front


*Field 15 - This value counts from near 0 to around 3FFF and rolls over, not sure what it is. Have not been able to correlate the counting value or speed vs time to any sort of power utilization.
'''** NEW **'''


'''Field 13''' - Timing in hundredths of a second, counts from 0 to 167.99 (0x419F) seconds then rolls over to 0 again. Credit for this discovery goes to an anonymous reader who examined the dataset at the bottom of the page!!

This table lists Real-time data requests from [https://www.smartmetertexas.com/home SmartMeterTexas.com] which allows customers to request current meter readings. 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.
