Hmmm, I wouldn't know. In both cases when I click twice, I see the the option to turn ON or turn OFF the hot water.

Thanks jannl. More testing is required apparently.

I did the following installed a new Pi3, version 3.5776 with just on device running, Nefit HTTP server

Will report back soon

However when using the on/off switch it seems to freeze / timeout once in a while.
My thermostat is always on manual mode, and I let my calander connected LUA do the switching of temperature and hot water.
For this way I think the CLI install is needed.

Code: Select all

 os.execute ("easy hot-water-supply on --serial=xxxx--access-key=xxxx--password=xxxx")

If the CLI is not installed you can also swtich the hot water with:

Code: Select all

pi@raspberrypi:~$ easy put /dhwCircuits/dhwA/dhwOperationManualMode '{"value":"off"}' --serial=xxxx--access-key=xxx --password=xxxx
{"status":"ok"}

This is how to retreive current status:

Code: Select all

pi@raspberrypi:~$ easy get /dhwCircuits/dhwA/dhwOperationManualMode --serial=xxxx--access-key=xxxx--password=xxxx
{"id":"/dhwCircuits/dhwA/dhwOperationManualMode","type":"stringValue","recordable":0,"writeable":1,"value":"off"}

The switch off of the button is either a readout fault or something with the button.
I can make a button to switch the hot water, however I can not read the data from the nefit and feed this to a domoticz button.
If I understand correct you need to readout the nefit status with the above or with:

Code: Select all

curl http://127.0.0.1:3000/bridge/ecus/rrc/uiStatus
curl http://127.0.0.1:3000/bridge/dhwCircuits/dhwA/dhwOperationManualMode

curl http://127.0.0.1:3000/bridge/ecus/rrc/uiStatus
{"id":"/ecus/rrc/uiStatus","type":"uiUpdate","recordable":0,"writeable":0,"value":{"CTD":"2016-10-22T09:15:22+01:00 Sa","CTR":"room","UMD":"manual","MMT":"19.0","CPM":"auto","CSP":"38","TOR":"off","TOD":"0","TOT":"19.0","TSP":"19.0","IHT":"19.00","IHS":"ok","DAS":"off","TAS":"off","HMD":"off","ARS":"init","FPA":"off","ESI":"on","BAI":"No","BLE":"false","BBE":"false","BMR":"false","PMR":"false","RS":"off","DHW":"off","HED_EN":"false","HED_DEV":"false","FAH":"false","DOT":"false","HED_DB":""}}

I think Domoticz uses something like this curl http://127.0.0.1:3000/bridge/ecus/rrc/uiStatus to read the nefit status?
The DHW:off or on status is the one of interest here!
and this needs to be translated from json to lua into a button in Domoticz!

I am not handy enough for this, but if I can help in any way let me know.

By the way, you need to set warm water as in the picture to be able to switch on/off hot water.
Also in manual mode!!

For installation of the easy server onto RasPi the Wiki is not 100% right, but with the help of the above posts (thank you all!) and good old friend Mr. Google, I just succeeded to get it all running in Domoticz.

I really like my new home automation hobby!
