Hi all
I’ve been trying to use the Hue api and some of my Lua knowledge to create an energy calculator based on the brightness and wattage of specific models of hue bulb registered on the hub
I’ve pretty much got there, the only stumbling block I have is how I total up all the individual bulb wattages. Can anyone help ?
It’s likely an easy thing for someone more experienced to see, but as I only dip in and dip out now and then, the correct code/syntax does not always come to mind.
Note : as I’ve tried various routes, I’ve commented some things out, but you should be able to get the idea of what I’m trying to do..
Create device json from Hue Hub
Decode JSON and extract key values to a table
Calculate approx watts based on bulb model and/or watts function
Total up watts of all bulbs that are switch on.
Code below...
local hueBridgeIP = '192.168.1.29'
local hueBridgeAPI = "80uCoXjnn2LNLhxEJ9PW6nmt-G5KWQ2uP3oONAvcm0j"
function getHueLight()
local http = require('socket.http')
local ltn12 = require('ltn12')
local json = require('dkjson')
t = {}
local url = string.format("http://%s/api/%s/lights", hueBridgeIP, hueBridgeAPI)
b, c, h = http.request{url=url, sink = ltn12.sink.table(t), method='GET'}
huestring = tostring(table.concat(t))
local hue, pos, err = json.decode(huestring, 1, nil)
huelights = {}
for k, v in pairs(hue) do
local modelno = string.gsub(hue[k]['modelid'], "%s+", "")
table.insert(huelights, {k, hue[k]['state']['on'], hue[k]['name'], hue[k]['state']['bri'], modelno, hue[k]['state']['reachable']})
print(k, hue[k]['state']['on'], hue[k]['name'], hue[k]['state']['bri'], modelno, hue[k]['state']['reachable'])
end
end
