wwonetimecharging not working

[Ivannefit]

Hello,

The ww one time charging does not work on my nefit enviline tower 2 (monoblock)

The option to adjust is not available EMS-ESP web interface.

In Domoticz is no hardware available for wwonetimecharging.

When i use the Nefit phone app the ww temperature is default on 70 degrees, The only thing i need to set is the time that extra ww wil be active .( varies from 15 min to 48 hours in steps of 15 min)

thanks. Could you also send the output of http://ems-esp/api/boiler/wwonetime to see if its writable

[Ivannefit]

You mean with MQTT exploder? I don know how te get the output.

[proddy]

no, EMS-ESP has an REST API. The URL will query EMS-ESP and bring back the ww onetime details. You may need to replace ems-esp with the IP address

[Ivannefit]

Ah ok. Here is the output

"name": "wwonetime",
"fullname": "ww one time charging",
"circuit": "ww",
"value": "off",
"type": "boolean",
"writeable": true
}

[proddy]

So we need to figure out why you can't change it from the Web UI. Just to be safe could you restart EMS-ESP and also Shift-Refresh your browser to make sure nothing is cached.

Also you can try setting the value directly from the Console. Telnet into EMS-ESP, do a su with the default system password and type call boiler wwonetime to see the settings and then try call boiler wwonetime on to change a value.

The feature from the Nefit app is interesting. We could consider making a new feature that does the same if you want - but then please create a new GitHub enhancement request with some specifications on how it works.

@Ivannefit Please use the latest dev-build, sunbuzz has recently fixed the (for some heatpumps) too small json buffer, cutting the pencil and some other paramters from webpage.

On some systems ww is only managed by thermostat and wwonetime-command on boiler does not work, than try thermostat wwcharge command.

[Ivannefit]

Ok i have done it with versie 3.2.1 and 3.2.2b5

Both not working

[MichaelDvP]

Both not working

As mentioned: Have you tried call thermostat wwcharge on. The command from terminal is send to the boiler, but the boiler ignores it. The dev fixes only the missing values on web-page.

[Ivannefit]

now i have tried call thermostat wwcharge on.

Still nothing happens

[MichaelDvP]

From here: Try with call system send "0B 10 FF 0B 01 F5 FF"

I think the thermostat command sends 1 instead of 0xFF.

[Ivannefit]

This one works, but default time is now 45 min. it would be nice to set the timer and be able to use it in domoticz

The status of ww one time charging in the web interface goes to on

[MichaelDvP]

Ok, i'll change the wwcharge-command to make it work. I think wwchargeduration can also be set in steps of 15min, doesn't it work?
With domoticz i can't help, i've never tried it.

[Ivannefit]

wwchargeduration is not in my web interface. Or is it wwactivetime?

[MichaelDvP]

Should be right before wwcharge in thermostat values. Please check call thermostat info and read 10 2F5

[Ivannefit]

Ya sorry was looking in boiler, wwchargeduration works properly

[Ivannefit]

i'm using 3.2.2.b8 now and all value that are writable in the web intrerface dont have a pull down menu.

cant switch between on and off

And when i type "on" the value dont change.

[MichaelDvP]

I think you're using a cached webpage, please reload page in browser.

[Ivannefit]

I have reload the de page and pull down menu's are back, Only wwonetimecharging isn't working

[MichaelDvP]

Only wwonetimecharging isn't working

As mentioned: if ww is managed by thermostat the boiler wwontime is not working, you have to use thermostat wwcharge, this should work now.
For systems with working boiler command it is only starting if the current temp is more than 5 degrees under setpoint, otherwise the boiler ignores the command.

[Ivannefit]

Ah ok ,sorry forgot about that. wwcharge is working!!!
