Hi.
I normally control my HifiBerry amplifiers with NodeRed and the HifiBerry API. I now try to do the same with my LM5, but i just get an error code. I want to send % volume to the amplifier. Anyone here who knows what to adjust to get this to work?

Code:
http = require('socket.http')
ltn12 = require('ltn12')
body = require('json').encode({
percent = event.getvalue()
})
res, code = http.request({
url = 'http://192.168.1.91:81/api/volume',
method = 'POST',
headers = {
['Content-Length'] = #body,
},
source = ltn12.source.string(body)
})
