Domoticz HTTP/HTTPS Poller command script for Shelly devices
Download https://raw.githubusercontent.com/mitkodotcom/shelly-domoticz-poller/master/shelly.lua and save it to domoticz/scripts/lua_parsers/
Add a HTTP/HTTPS poller in Hardware. Give it a name.
URL: http://192.168.1.123/status (where 192.168.1.123 is the IP address of your Shelly)
Command: shelly.lua
Rerresh: 10
Click on "Create Virtual Sensors" next to the just added poller and add Electric (Instant + Counter) device. Find it's index number in Devices. Enter this number as power_index[0] in shelly.lua. Repeat, if your device has more than one power meter.
Add a Dummy hardware device and create another Virtual Sensor of type Switch. DO NOT (I repeat: DO NOT) create the virtual Switch under the poller hardware, use the Dummy device instead or you will not be able to control the On/Off function (see below). Repeat if you have more than one relay.
Find the switch in Switches tab and click Edit. Give it a name. Enter this name as switch_name[0] in shelly.lua
If the switch is in Relay mode:
Switch Type: On/Off
On Action: http://192.168.1.123/relay/0?turn=on
Off Action: http://192.168.1.123/relay/0?turn=off
Set num_rollers = 0 in shelly.lua
If the switch is in Roller mode:
Switch Type: Blinds
On Action: http://192.168.1.123/roller/0?go=close&duration=40
Off Action: http://192.168.1.123/roller/0?go=open&duration=40
Set num_rollers = 1 (or whatever number of rollers you have) in shelly.lua
The duratuion is in seconds - use whatever is suitable for your roller.
Note that the Blinds reaction is inverted: "close" for "On" and "open" for Off
Repeat if you have more than one relay / roller to control (note that Shelly2 has two relays if in switch mode but only one roller). Do not forget to replace the "0" after relay/ and roller/ with 1,2,3, etc.
Update the corresponding values of num_meters and num_outputs in shelly.lua
