home automation

Prep

• install OS (Ubuntu)
• install asdf
• install node
• install Git
• install influxDB

First exploration of commands

• install smartthings cli first
• smarthings devices lists all devices - to get the id of the device (heatpump)

Already gives me the most important info

• smartthings devices:status [ID]

Plan

• write a polling script in node to poll a. smartthings b. wetherdata (temperature, sunshine hours)
• push data to influxDb
• use Grafana or similar to visualize (maybe only Fore + lib)

HomeBridge

install homebridge

npm install -g --unsafe-perm homebridge homebridge-config-ui-x

start homebridge service

sudo hb-service install –-user homebridge

OK, here's the definition of the values:

start: Start date of the reporting period in Iso8601Date format
end: End date of the reporting period in Iso8601Date format
energy: Accumulated energy consumption during the reporting period in watt-hours (Wh)
power: Instantaneous power consumption during the reporting period in watts (W)
deltaEnergy: Delta of accumulated energy consumption during the reporting period in watt-hours (Wh)
powerEnergy: Energy consumption during the reporting period calculated from instantaneous power consumption in watt-hours (Wh)
energySaved: Energy saved during the report period in watt-hours (Wh)
persistedEnergy: Accumulated energy consumption that was saved into device local DB in watt-hours (Wh)

Note: I don't know the frequency or logic behind when a "report" is generated, but I suspect it correlates to a cycle on the appliance. Based on the definition above, energy is not cumulative, rather will get reset every "report". If your goal is to determine total energy used (on-going), you'll need to create a separate sensor for total energy that adds the value of energy whenever it's updated (when a new report comes out).

I'm happy to submit a PR for this, unless @JPHutchins wants to. 😄
