Qubino thermostat mode ZMNHID1

[mhendel]

Hello,

Firstable, sorry for my English. My mother tongue is french.

I have a qubino ZMNHID1, which have a thermostat mode switch placed in the Utility Tab. This switch can take the values "On" or "Auto".
The problem is that, randomly, this switch changes from Auto to Off, which is not cool for a thermostat .

I try to write a LUA script which change the state of this switch when it pass to off.

I am a newbie with LUA.

In LUA, the value of the Thermostat mode switch can be either 0 (Off) or 1 (Auto). The type is string.

Here is my simple script :

function delay_s(delay)
delay = delay or 1
local time_to = os.time() + delay
while os.time() < time_to do end
end

commandArray = {}
if devicechanged['Bureau_Thermostat_Mode'] == '0' then
Delay_s(5)
commandArray['Bureau_Thermostat_Mode']='1'

end

And... It doesnt work at all. The switch remains to 'Off'.

Any idea? I am stuck with this since 2 days...HELP!!!!!

No answer? Any hint?

After google it appears to be an error in OpenZwave
https://github.com/OpenZWave/open-zwave/issues/1065

I myself have the Qubino ZMNHAD1 (flush relay) I am using it so, that in zwave configuration I have set the relay to be auto switch off after 2 min. then in Domoticz I measure the temperature and if it's below my threshold I switch on the relay, that then put my Electrical radiator on (for 2 min)
Maybe you can use something similar approach?

I have this device and it shows two modes: OFF and Auto. If I set mode to OFF, the heater is disconnected. When I ser mode to Auto hte heater switch ON if temperature is under the setpoint and switch OFF if temperature is over setpoint.
It doesn't change to OFF by itself.

PD: the OZW issue was fixed, this error was a program fault about index in array.

Thanks for your answer. I know how the mode is running. But unfortunately, i have a problem with this thermostat. In other words, what is wrong with my LUA script?

[mhendel]

Or in other words, how to change the state of a utility switch, with LUA?

[juankar]

I'll tell you about my system: it's a bath heater used to dry towells-
Thermostat use several devices, I need these one:
-A setpoint I name as SecaToallas-Termo
-A thermostat mode I name as SecaToallas-Inter
- I've created a virtual switch named SecaToallas

My lua switches AUTO/OFF when I switch ON/OFF my virtual switch, and If I change thermostat by hand (locally) then it changes the virtual swtich status.
The lua script is named script_device_Secatoallas (an script triggered when devices change)

Code: Select all

commandArray = {}

virtual  = "SecaToallas"
idx = otherdevices_idx["SecaToallas-Inter"]
idxV = otherdevices_idx[virtual]
-- This check if thermostate has changed by hand, locally not by domoticz
if (devicechanged_ext["idx"] == idx) then
    if (devicechanged_ext["nvalue"] == 1 and otherdevices[virtual] == "Off") then
        commandArray['UpdateDevice'] = idxV.."|1|On "
    elseif (devicechanged_ext["nvalue"] == 0 and otherdevices[virtual] == "On") then
        commandArray['UpdateDevice'] = idxV.."|0|Off "
    end
end
-- This check if virtual switch has changed
if devicechanged[virtual] == 'Off'  then
      commandArray['UpdateDevice'] = idx.."|0|0"
elseif devicechanged[virtual] == 'On' then
      commandArray['UpdateDevice'] = idx.."|1|1"
end   
return commandArray

I hope this is useful for your system.
Bye

Thanks Juankar, it helped me a lot!

By the way, dont you have a good manual or tutorial concerning LUA for domoticz? Like for dummies (as i am)?

A thousand thanks.

Wiki of Domoticz offers some information about use of LUA, but to learn LUA you need to search for a tutorial
A good tutorial or manual? It depends on your acknowdlge about programing.
I should start with https://www.lua.org/, there are a lot of info in this site.

Bye.
