Hot Water log

[josvink66]

Hello,

I was wondering if there is any way to log when and how long the hot water is running?

Or just simply query if hot water is currently being used.
I know the boiler status shows hot water and off. But with domoticz sometimes the central heating starts before the off signal for the hot water is received. So then the off signal is for the central heating.

Any help would be appreciated.
Reactie in het Nederlands mag ook :)

Greetings,

This sounds like an issue that should be solved in Domoticz. I don't think that the Easy internally tracks how long the hot water was active, so the only way to find out how long hot water was being used is to regularly check (perhaps once a minute, if that's possible with Domoticz?) if the boiler indicator value has changed.

Hello Robert,

What i then would like to do is write my own script to poll the Nefit Easy Server and store the results.
If i run the following command i can see the Boiler statsus just like in domoticz. curl http://127.0.0.1:3000/api/status

Is there any other command to only check if hot water is being used at that moment?

I honestly have no idea. But there's a list of endpoints here, perhaps there's one that will reflect if hot water is being used at the moment: https://github.com/marcelrv/nefit_easy_protocol

Make sure that you use http://127.0.0.1:3000/bridge/... (and not http://127.0.0.1:3000/api/... for those endpoints.
