Question about zwave_thermostat_mode_device.lua

I have the Heatit zwave thermostat and i had problems to get the 'eco' working with a selector switch.
There are some people who got it working to use nvalue2 but that did not work for me so i tried nvalue3 which works fine:

http://127.0.0.1:8080/json.htm?type=com ... 8&nvalue=3

So will this line work in the zwave_thermostat_mode_device.lua?
-- modes from data: ["modes"] = "0;Off;1;Heat;2;Heat Econ;";

Also where is this file used for and what can i do with it?

Hi,

zwave_thermostat_mode_device.lua in dzVents/runtime/device-adapters folder is script used internally by dzVents runtime for handling this type of device (deviceSubType == 'Thermostat Mode'). So you can easier get status and send updates to device.

Line with modes is commented out (by double dash --) and is only example of device modes (from my system ;) )

Doc for this type of device is on Wiki
https://www.domoticz.com/wiki/%27dzVent ... ostat_mode

Example of dzVents script part:

Code: Select all

-- assign device variable
local dev = domoticz.devices('Some device')

-- log current mode
domoticz.log('Current mode: ' .. tostring(dev.modeString))
-- log available modes
domoticz.log('All modes: ' .. tostring(dev.modes))

-- update mode
dev.updateMode('Off')

-- dump all device info for debugging
dev.dump()

So you have one.
Can you check if yours also needs nvalue 3 for eco or nvalue 2 for eco?
Can you tell me which software version it is running?

PS. i still don't get it very well except that the script is for processing it in dzVents.

I have Comet Z-Wave thermostatic radiator valves. It has Heat Eco mode nvalue=2, but modes can differ by Zwave hardware vendor and type. Do you try to dev.dump() in dzVents script to see modes ?

Same info should be visible in JSON data of device (Modes:). Try this - replace ip, port and IDX with yours:

That json only gives me sunset,sunrise and time, nothing more.
What should i do with dev.dump()?
Not everybody is a coder so just saying to put it in a script doesn't work for me.
Maybe somebody should write an example script for this kind of stuff.
This will help you guys out a lot more :)

OK, lets start with basics ;)

Every Domoticz device (switch, sensor, thermostat etc.) has unique IDX. You can get it on Setup / Devices page. Find your device and in column Idx it is:
2017-08-10 10_20_24-Domoticz.png
2017-08-10 10_20_24-Domoticz.png (47 KiB) Viewed 2260 times

Take this IDX and modify this URL by your data:

2017-08-10 10_21_46-192.168.17.131_8080_json.htm_type=devices&rid=3.png

You should see web page full of parameters of your device in JSON format. This way, you get device data, which Domoticz knows about your device. Please post JSON here.

I know about the IDX but i feel so stupid now, i did not remove IDX in the link but added the IDX right after it :roll:
This is what is coming back:

OK, don't worry.

So your Zwave thermostat has these available modes:

Code: Select all

"Modes" : "0;Off;1;Heat (Default);2;Cool;3;Energy Heat;"
dzVents script for changing modes can look like this:

Code: Select all

local LOGGING = true -- log status info

return {
        active = true,
        on = {
                devices = {
                        'Eco switch'    -- example switch device - if On, change mode to Eco
                }
        },
        execute = function(domoticz, device, triggerInfo)
              local newMode -- new mode variable
              local devTherm = domoticz.devices('Thermostat Mode woonkamer') -- thermostat device variable
              local devMode = devTherm.modeString -- current mode variable
              
              if device.state == 'On' then
              -- if Eco switch is On, change mode to Eco
                    newMode = 'Energy Heat'
              else
                    newMode = 'Heat (default)'
              end
              
              if LOGGING then
                    domoticz.log('current mode: ' .. devMode)
                    domoticz.log('new Mode: ' .. newMode)
              end
              
              if devMode ~= newMode then
              -- check if newMode not already set
                     domoticz.log('setting to: ' .. newMode)
                     devTherm.updateMode(newMode)
              else
                     domoticz.log('already set: ' .. newMode)
              end
        end
}

I'm having a problem trying to change modes with my new zwave thermostat

Code: Select all

	local DownMode = domoticz.devices('Thermostat Downstairs Mode')
	--Modes: "0;Off;1;Heat;2;Cool;3;Auto;4;Aux Heat;"
	local ModeSet = domoticz.variables('ThermostatDownModeSet')
	local newmode
    if (ModeSet.changed) then 
        if (ModeSet.value == 0) then
            newMode = 'Off'
        end
        if (ModeSet.value == 1) then
            newMode = 'Heat'
        end
        if (ModeSet.value == 2) then
            newMode = 'Cool'
        end
        DownMode.updateMode(newMode)
    end    
end
--2017-08-14 22:10:00.513 Error: dzVents: Error: An error occured when calling event handler ThermoDownMode
--2017-08-14 22:10:00.513 Error: dzVents: Error: ...icz/scripts/dzVents/generated_scripts/ThermoDownMode.lua:28: attempt to call field 'updateMode' (a nil value)
}
I added the errors to the end of my code, line 28 is the updateMode line

Any advice would be appreciated, can't see what I'm doing wrong.

Hi Randy,

It looks like your device DownMode has no updateMode method. Which version of Domoticz / dzVents are you using ? Please check also attributes of your device in dzVents script by:

Code: Select all

DownMode.dump()
and JSON call - replace ip, port and IDX with your values:

http://domoticz-ip:port/json.htm?type=devices&rid=IDX

I was using version 2.1.0
I updated to 2.2.0 and it started working :D
So thanks for asking, that fixed it. Since my sw skills are pretty basic, I always assume I'm doing something wrong lol.

So now I'll be able to set a user variable, and change the mode. I want to do this because I can't change modes from an app, but I can change a user variable value. I'll probably make it 0 = off and 1 = auto so it's easy to remember.
I'm also going to make a time based script, which will turn off the downstairs thermostat at night, in case we forget lol. It will also turn off the upstairs thermostat during the day.

:) Great !

I am using updateMode similar way - uservariable 0 / 1 for setting thermostats to off in summer. There is one way of changing setting in web Gui - Edit device on Utility page, and there are modes.

Yeah, I can change modes from a PC with no problem, from the Utility page. But I wanted to be able to change modes from any device, just in case.
And now I can, with my new script.
