Lua to virtual multisensor, just short of success?
Posted: Sunday 18 November 2018 10:04
I use http/https polling and a lua script to (eventually) get my virtual multisensor populated with data.
The lua-script is close to fulfillment, just lacking the actual returning of data to my virtual sensor .. I would really appreciate help with the final push ?
Virtual sensor is "add hardware", http/https poller with my url. Returns data, all good. Then create virtual sensor, Temp + Humidity + Baro, my idx=135 - and script is /scripts/lua_parsers/yr.lua.
Debugging with print, all values look good, no error messages.. but I must be doing something wrong, perhaps in declaring commandArray, how I use commandArray or formatting of the return value ?
if i print my return value it looks like this, and it is what I intended:
2018-11-18 10:01:46.447 CLuaHandler: udevices: 135|0|1.9;93.1;0;1044.3;0
I have cheated by looking at this viewtopic.php?t=11577
