in dzVents: something like this ?

Code: Select all

 --[[ 
    th15Test
    checkFirst() available in dzVents > 2.3.0
]]-- 
 
return { 
    on = { timer = { 'at 06:00-22:00 every 5 minutes'},
          },

    execute = function(dz,_)
        if dz.devices("HotWater:temp").temperature <= 40 then 
            dz.devices("HotWater:Relay").switchOn().checkFirst()
        elseif dz.devices("HotWater:temp").temperature >= 50 then
            dz.devices("HotWater:Relay").switchOff().checkFirst()
        end
end
}

Kre10, some remarks:
- Nested IF is not allowed (remove the outer IF)
- Use the IF with the blue star when ELSE is involved (correct for your inner IF)
- use a Dummy Switch Device and let it switch ON at 6 and switch OFF at 22hr (with the Timer of the device)
- combine this Dummy Switch in the IF part and in the ELSEIF part
- make sure the Blockly is of the type "Devices"

No need for scripts !

end
}

What will the state of the relay be from 22:00 to 06:00?

[kre10]

i need to control temperature for daytime from 06:00-22:00 - 50C and from 22:00 to 06:00 - to max or 70C maximum
but when i test dzVents script not work correctly, i mean doesn't turn on switch but my temp is 30C. when i test

i think i solve my problem with https://www.domoticz.com/wiki/Plugins/S ... ostat.html

I think this is the right way with blockly:

If Time ≥ 06:00 And Time ≤ 21:59 And HotWater: temp ≤ 40 And HotWater: Relay = Off
Set HotWater: Relay = On
Else If Time ≥ 06:00 And Time ≤ 21:59 And HotWater: temp ≥ 50 And HotWater: Relay = On
Set HotWater: Relay = Off
Else If Time ≥ 22:00 And Time ≤ 05:59 And HotWater: temp ≤ 70 And HotWater: Relay = Off
Set HotWater: Relay = On
Else If Time ≥ 22:00 And Time ≤ 05:59 And HotWater: temp ≥ 70 And HotWater: Relay = On
Set HotWater: Relay = Off
