Support for lua scripts

The SLS gateway has support for automation based on the scripting programming language lua. The script editor is located in the Actions -> Scripts menu.

To write a script, you need to create a new file, for example, with the name script.lua and enter the code in the lua language into it.

The script stdout on the print command prints information to the screen of the Scripts page and to the system log of the gateway. You can start the test script by pressing the RUN button.

When the gateway starts, the /init.lua file is executed

Options for running scripts

Run the script when the state of the device changes. On the Zigbee tab, you need to go to the device parameters and in the SimpleBind window specify the name of the script file (prefix "/" is optional) .
Run the script on time. Expected.
Running the script by mqtt subscription. Expected.
Running the script when calling the http api. /api/scripts?action=evalFile&path=/test.lua.

List of available functions and structures

http.request

Calling the request URL http.request (url[:port],[method,headers, body])

Currently only the http:// protocol is supported.

Example switching gpio 12 for wifi-iot firmware

http.request ("http://192.168.1.34/gpio?st=2&pin=12")

http.request ("http://192.168.1.34/gpio?st=2&pin=12")

An example of sending a POST request:

http.request ("http://postman-echo.com:80/post?foo1=bar1", "POST", "Content-Type:text/text; charset=utf-8\r\n", "body ")

http.request ("http://postman-echo.com:80/post?foo1=bar1", "POST", "Content-Type:text/text; charset=utf-8\r\n", "body ")

Example of switching relay sw1 in espHome firmware:

http.request("http://192.168.1.71/switch/sw1/toggle", "POST")

http.request("http://192.168.1.71/switch/sw1/toggle", "POST")

An example of switching gpio for MegaD by pressing btn_2 once on the Jager remote

if Event.State.Value == "btn_2_single" then
  http.request("http://192.168.2.200/objects/?object=MegaD1-12&op=m&m=switch")
end

if Event.State.Value == "btn_2_single" then
  http.request("http://192.168.2.200/objects/?object=MegaD1-12&op=m&m=switch")
end

Request for information from a third-party resource

local Response = http.request("http://wtfismyip.com/text")
print("My IP:" .. Response)

local Response = http.request("http://wtfismyip.com/text")
print("My IP:" .. Response)

zigbee.value()

Getting device status value from cache zigbee.value ("ieeard", "temperature")

-- We get the temperature value and round to the nearest integer
temp = zigbee.value ("0x00158D0001A2D2FE", "temperature")
temp = math.floor(temp)
print ("Current temperature:" .. temp .. "C °")

-- We get the temperature value and round to the nearest integer
temp = zigbee.value ("0x00158D0001A2D2FE", "temperature")
temp = math.floor(temp)
print ("Current temperature:" .. temp .. "C °")

Instead of the device address, you can use FriendlyName (including Cyrillic), or the current device address on the network (0x9EC8).

-- We get the temperature value and round to whole
temp = zigbee.value ("room sensor", "temperature")
temp = math.floor (temp)
print ("Current temperature:" .. temp .. "C °")

-- We get the temperature value and round to whole
temp = zigbee.value ("room sensor", "temperature")
temp = math.floor (temp)
print ("Current temperature:" .. temp .. "C °")

zigbee.get ()

Calls a GET command in a carpet. Used to manually read states from devices.

Example:

zigbee.get ("lamp1", "brightness")

zigbee.get ("lamp1", "brightness")

zigbee.join ()

Syntax: zigbee.join (duration, [target])

Opens the network for connecting new devices for duration seconds (max. 255), for the target device or for the entire network.

zigbee.join (255, "plug1")

zigbee.join (255, "plug1")

zigbee.set ()

Setting device value zigbee.set (Ident, StateName, StateValue)

An example of a script that, when the lumi.sensor_switch button is pressed, turns on the lamp_1 lighting:

if zigbee.value ("lumi.sensor_switch", "click") == "single" then
  -- toggle lamp
  current_brightness = zigbee.value ("lamp_1", "brightness")
  if current_brightness == 0 then
    zigbee.set ("lamp_1", "brightness", 255)
  else
    zigbee.set ("lamp_1", "brightness", 0)
  end
end


-- switch 0x00124B0009FE36FC on single lumi.sensor_switch click
if Event.State.Value == "single" then
  zigbee.set ("0x00124B0009FE36FC", "state", "toggle")
end

if zigbee.value ("lumi.sensor_switch", "click") == "single" then
  -- toggle lamp
  current_brightness = zigbee.value ("lamp_1", "brightness")
  if current_brightness == 0 then
    zigbee.set ("lamp_1", "brightness", 255)
  else
    zigbee.set ("lamp_1", "brightness", 0)
  end
end


-- switch 0x00124B0009FE36FC on single lumi.sensor_switch click
if Event.State.Value == "single" then
  zigbee.set ("0x00124B0009FE36FC", "state", "toggle")
end

Event

The Event structure, for example, allows you to use the same script for different states or devices.

Possible use cases:

Event.Name - The name of the script file
Event.nwkAddr - the nwkAddr of the device that called the script
Event.ieeeAddr - ieeeAddr of the device that invoked the script
Event.FriendlyName - FriendlyName of the device that called the script
Event.State.Name - The name of the state that caused the script
Event.State.Value - New state value

An example of a script to turn on the light:

if Event.State.Value == "single" then
  value = 255
elseif Event.State.Value == "double" then
  value = 0
else
  return
end
zigbee.set ("lamp_1", "brightness", value)

if Event.State.Value == "single" then
  value = 255
elseif Event.State.Value == "double" then
  value = 0
else
  return
end
zigbee.set ("lamp_1", "brightness", value)

os.time()

os.time() returns Unix time.

An example of getting the current hour, time and seconds, for example, for a scheduler in a timer:

local gmt = 3
local time = os.time () + gmt * 3600;

local t1 = math.modf (time/60);
local sec = time - t1 * 60;
local time = t1;
local t1 = math.modf (time/60);
local min = time - t1 * 60;
local time = t1;
local t1 = math.modf (time/24);
local hour = time - t1 * 24;

print (hour .. ":" .. min .. ":" .. sec)

local gmt = 3
local time = os.time () + gmt * 3600;

local t1 = math.modf (time/60);
local sec = time - t1 * 60;
local time = t1;
local t1 = math.modf (time/60);
local min = time - t1 * 60;
local time = t1;
local t1 = math.modf (time/24);
local hour = time - t1 * 24;

print (hour .. ":" .. min .. ":" .. sec)

os.delay()

Syntax: os.delay(ms)

Pause for ms milliseconds (1sec = 1000ms)

os.millis()

Returns the number of milliseconds since system boot

os.save()

Saves data

os.restart()

Reboots the OS

os.ping(host [, count])

Sends ICMP PING requests, returns average time or -1 if unavailable.

os.led(r, g, b [, mode])

r, g, b - integers 0-255, sets the gateway LED color. You can use -1 for the corresponding color if you don't need to change it.

mode:

0 - off,
1 - manual,
2 - auto

obj.get() / obj.set()

obj.get(ObjectName) / obj.set(ObjectName, ObjectValue) to save and get an object for exchanging data between scripts

Checking for the existence of an object:

local status = obj.get ("security.status")
if (status == nil) then status = 0 end

local status = obj.get ("security.status")
if (status == nil) then status = 0 end

mqtt.pub()

Syntax: mqtt.pub(topic, payload)

Publishes the payload value to the MQTT server in the topic topic.

Example of relay control on Tasmota firmware - cmnd/device_name/relay_name

mqtt.pub('cmnd/sonoff5/power', 'toggle')

mqtt.pub('cmnd/sonoff5/power', 'toggle')

Enabling "pairing mode" by pressing the side button of the gateway

When the button is clicked, the btn_sw1.lua script is called Add the following code to your script:

zigbee.join(255, "0x0000")

zigbee.join(255, "0x0000")

GPIO control

gpio.mode(pin, mode)

Simplified sending of messages in telegrams (starting from version 20200915)

Register your bot at @BotFather. token issued to you during bot registration.
Find out your ChatId from the @userinfobot.

It is enough to write the token and ChatId once in init.lua, then use only telegram.send() :

-- add in init.lua
telegram.settoken ("5961 ....: AAHJP4 ...")
telegram.setchat ("5748 .....")

-- add to other lua scripts
telegram.send ("Temperature:" .. string.format ("%.2f", zigbee.value (tostring (Event.ieeeAddr), "temperature")) .. "° C, Humidity:" .. string.format ("% .2f", zigbee.value (tostring (Event.ieeeAddr), "humidity")) .. "%")

-- add in init.lua
telegram.settoken ("5961 ....: AAHJP4 ...")
telegram.setchat ("5748 .....")

-- add to other lua scripts
telegram.send ("Temperature:" .. string.format ("%.2f", zigbee.value (tostring (Event.ieeeAddr), "temperature")) .. "° C, Humidity:" .. string.format ("% .2f", zigbee.value (tostring (Event.ieeeAddr), "humidity")) .. "%")

Converting pressure readings from kPa to mmHg

You need to create a lua script that will be called when the pressure changes:

local press = zigbee.value(tostring(Event.ieeeAddr), "pressure")
local pressmm = zigbee.value(tostring(Event.ieeeAddr), "pressure_mm")
if pressmm == null then
  zigbee.add(tostring(Event.ieeeAddr), "pressure_mm", "FLOAT")
end
zigbee.set(tostring(Event.ieeeAddr), "pressure_mm", press * 7.5)

local press = zigbee.value(tostring(Event.ieeeAddr), "pressure")
local pressmm = zigbee.value(tostring(Event.ieeeAddr), "pressure_mm")
if pressmm == null then
  zigbee.add(tostring(Event.ieeeAddr), "pressure_mm", "FLOAT")
end
zigbee.set(tostring(Event.ieeeAddr), "pressure_mm", press * 7.5)

Requesting data from devices through a script, for example, requesting instant consumption, if the device itself does not notify

Add zigbee.get("0x842E14FFFE05B8E2", "power") in the onemintimer.lua file where 0x842E14FFFE05B8E2 is the device identifier

An example of working with an astrotimer

Astrotimer is a regular timer that is tied to the sunset / sunrise cycles. Since at different latitudes the time of sunset and sunrise is different, then in such timers there is a longitude / latitude setting. Longitude / latitude parameters are set via the Web in the Settings -> Location tab.

Astrotimer is called by the OnMinTimer.lua script every minute:

local sunrise_add_min <const> = 15
local sunrise_hour, sunrise_min = os.sunrise ()
sunrise_min = sunrise_min + sunrise_add_min
if sunrise_min > 59 then
  sunrise_hour = sunrise_hour + 1
  sunrise_min = sunrise_min - 60
end
if Event.Time.hour == sunrise_hour and Event.Time.min == sunrise_min then
  print (sunrise_hour .. ":" .. sunrise_min)
end

local sunrise_add_min <const> = 15
local sunrise_hour, sunrise_min = os.sunrise ()
sunrise_min = sunrise_min + sunrise_add_min
if sunrise_min > 59 then
  sunrise_hour = sunrise_hour + 1
  sunrise_min = sunrise_min - 60
end
if Event.Time.hour == sunrise_hour and Event.Time.min == sunrise_min then
  print (sunrise_hour .. ":" .. sunrise_min)
end

This script will print the time of dawn, 15 minutes after the onset, i.e. if dawn comes 8:55, add 15 minutes, then the script will work at 9:10. You can ask no more than 60 minutes.

Example of using astrotimer

local sunset_add_min <const> = 20
local sunset_hour, sunset_min = os.sunset()
sunset_min = sunset_min + sunset_add_min

if sunset_min > 59 then
  sunset_hour = sunset_hour + 1
  sunset_min = sunset_min - 60
end

if Event.Time.hour == sunset_hour and Event.Time.min == sunset_min then
  -- Turns on street light 20 minutes after sunset
  telegram.send ("Street lights on")
  http.request ("http://192.168.2.200:8888/objects/?object=MegaD3-8&op=m&m=extended")
end

local sunrise_add_min <const> = 1
local sunrise_hour, sunrise_min = os.sunrise ()
sunrise_min = sunrise_min + sunrise_add_min

if sunrise_min> 59 then
  sunrise_hour = sunrise_hour + 1
  sunrise_min = sunrise_min - 60
end

if Event.Time.hour == sunrise_hour and Event.Time.min == sunrise_min then
  -- Opens the curtains after dawn
  telegram.send ("The curtains in the living room are open")
  zigbee.set ("0x5C0272FFFEC8A21B", "position", 0)
end

local sunset_add_min <const> = 20
local sunset_hour, sunset_min = os.sunset()
sunset_min = sunset_min + sunset_add_min

if sunset_min > 59 then
  sunset_hour = sunset_hour + 1
  sunset_min = sunset_min - 60
end

if Event.Time.hour == sunset_hour and Event.Time.min == sunset_min then
  -- Turns on street light 20 minutes after sunset
  telegram.send ("Street lights on")
  http.request ("http://192.168.2.200:8888/objects/?object=MegaD3-8&op=m&m=extended")
end

local sunrise_add_min <const> = 1
local sunrise_hour, sunrise_min = os.sunrise ()
sunrise_min = sunrise_min + sunrise_add_min

if sunrise_min> 59 then
  sunrise_hour = sunrise_hour + 1
  sunrise_min = sunrise_min - 60
end

if Event.Time.hour == sunrise_hour and Event.Time.min == sunrise_min then
  -- Opens the curtains after dawn
  telegram.send ("The curtains in the living room are open")
  zigbee.set ("0x5C0272FFFEC8A21B", "position", 0)
end

Execution of the script by time

An example of completing a task at the appointed time

if Event.Time.hour == 15 then
  if Event.Time.min == 0 then
    -- turn on
  elseif Event.Time.min == 1 then
    -- turn off
  end
end

if Event.Time.hour == 15 then
  if Event.Time.min == 0 then
    -- turn on
  elseif Event.Time.min == 1 then
    -- turn off
  end
end

Run lua script from other script

dofile("/int/test.lua")

dofile("/int/test.lua")

Run lua script via HTTP API

/api/scripts?action=evalFile&path=/test.lua

/api/scripts?action=evalFile&path=/test.lua

Run lua script periodically

SLS gateway can run script periodically. To do this just create scripts with corresponding dedicated names: onesectimer.lua, onemintimer.lua.

onehourtimer.lua - will not start by gateway, but you can simulate it using onemintimer.lua:

if Event.Time.min == 0 then
  dofile("/int/onehourtimer.lua")
end

if Event.Time.min == 0 then
  dofile("/int/onehourtimer.lua")
end

⚠️ Warning, periodic scripts will work after gateway reboot!!!

Initialization script

При запуске системы единоразово выполняется init.lua . В нем полезно задать переменные для работы с устройством. init.lua is executed once on gateway starts up. It's useful to initialize common variables here.

telegram.settoken("51778***5:AAG0bvK***")
telegram.setchat("-3348***")
telegram.send("SLS started!!!")

local sunset_hour, sunset_min = os.sunset()
local sunrise_hour, sunrise_min = os.sunrise()
telegram.send("sunrise " ..sunset_hour  ..":".. sunset_min )

telegram.settoken("51778***5:AAG0bvK***")
telegram.setchat("-3348***")
telegram.send("SLS started!!!")

local sunset_hour, sunset_min = os.sunset()
local sunrise_hour, sunrise_min = os.sunrise()
telegram.send("sunrise " ..sunset_hour  ..":".. sunset_min )
