It would be great if not only the data can be read, but you could control a switch when a certain amount of netto energy is ‘over’. For instance: if 2 kW is delivered to the net, switch on the electricaly heated water buffer. Specially with the disapearing ‘salderingsregeling’. ---

Isn’t that the function of Homey…? The app delivers you data and with Homey you can decide what to do with it, for instance switching on the electrically heated water buffer. ---

Correct, you will get a measure\_power that can go negative (you are delivering back to the net) and hence with Homey you activate anything you like. The app I am working on is purely delivering the integration data and a flow trigger. ---

Ok an update from me. As of yesterday I received the Homewizard Wifi dongle that got supported by several donations. I would like to thank those that did a paypal donation. I’ve started coding here on github which is basically a re-code from the original Homewizard Application but without all the subparts. I utilize the existing JSON request but struggle a but with getting the JSON payload parsed in the “getStatus” function that resides in the driver. Maybe some more advanced javascript developer knows the error I made or brain-fart which is currently bugging me. Stairing blind after a few hours and 1am going to bed is not good. Source code is here: [https://github.com/jtebbens/Homewizard-Energy](https://github.com/jtebbens/Homewizard-Energy) ---

Unfortunately I cannot help you with your Javascript question, @Jeroen_Tebbens. But I have ordered the HW P1 dongle and it will arrive tomorrow. So if you need someone for testing, feel free to contact me. Can do a cli install if needed. ---

Thanks @Henk_Renting I will let you and others know when it is ok to test. Current version in github runs as an app, you can add the device but it fails to import/update the values in the meters on the device so useless for now. But app-wise its a start. ---

Just installed the Github version. Like a charm! So that part is working fine here. 🙂 Will try to install/connect the dongle tomorrow after I have received it. ---
