local alarm = 'doorbell'
local valuetrigger = '123456'

commandArray = {}

for deviceName,deviceValue in pairs(otherdevices) do
if (deviceName== doorbell) then

if tonumber(deviceValue) = tonumber(valuetrigger) then
commandArray['Google Home downstairs'] = "SendNotification Here's someone at the door'
