#Rainforest EAGLE™ Energy Access Gateway# The Eagle lets you retrieve the data from your smart meter locally with out having to pull the data from the cloud.

You will need to add the gateway to your energy meter through your electric company. Here in Texas there is a website devoted for smart meters. SmartMeterTexas.com

After the gateway is added to the meter you will need to disable local security.

In the web portal click the down arrow next to date. at the bottom of that page click the gear.

Gear

uncheck the security box.

Security

While you are in the Eagle gateway page look at the URL at the top and note the IP and MAC for setting up the .RULES file.

MAC

In my setup I created separate item and rule files for power.

power.items

Group	GPersist (All)
Group	GMonitorPower
Group	GMonitorEnergy

Number   HousePowerInstant    "SmartMeter Power [%.3f]" 	<energy>	(GMonitorPower,GPersist)
Number   HouseEnergyDelivered "SmartMeter Energy Delivered [%.3f]" (GMonitorEnergy,GPersist)
Number   HouseEnergySent      "SmartMeter Energy Sent [%.3f]" (GMonitorEnergy,GPersist)
Number   HouseEnergyPrice     "SmartMeter Energy Price [%.3f]" (GMonitorEnergy,GPersist)
Number   HouseEnergyCost      "SmartMeter Energy Cost [%.3f]" (GMonitorEnergy,GPersist)

Note: When you update the EAGLE_URL and the EAGLE_MAC, note the MAC is 18 characters starting with "0x"
