LUA script example for http poller
Posted: Monday 11 June 2018 9:41
Victor requested the LUA script I'm using in Domoticz to parse weewx weather data. This script lives in /home/pi/domoticz/scripts/lua_parsers.
Here are the hardware device settings in Domoticz:
The file current.json is generated by weewx and is saved in /home/pi/weewx/public_html

Code: Select all
--lua script to parse json data (in this case from weewx) to http/https poller virtual hardware
