I have installed the P1 monitor Versionn 9.6 on the raspberry pi. This works correct. I can connect with the App or by browser. On Homey I have downloaded Ztatz P1 monitor (Verbruik) but as I fill out the Ip address in can not connect. It returns the message [error.invalid\_data]. Anybody has any idea what to do? ---

Hi Ruud, Of course, that result with the same response. Also https:// doesn’t work. Verzonden door [Blue](http://www.bluemail.me/r?b=15726) Op 1 dec. 2019, om 21:29, Ruud Cornelisse via Homey Community Forum [athom@discoursemail.com](mailto:athom@discoursemail.com) schreef: ---

Please open the API in ZTATZ in the admin panel. Please review the url’s it displays. What I’m expecting is links that look like 192.168.1.100/api/v1/\*\*\*\*\*\* (depending on your IP) If there is a folder between the IP and the API folder you should also enter that within the app’s config. What version are you running currently of ztatz. Please make sure you update it if it is an older version ---

Same as pointed to above please review the ZTATZ admin panel. And go to API. What I’m expecting is links that look like 192.168.1.100/api/v1/\*\*\*\*\*\* (depending on your IP) If there is a folder between the IP and the API folder you should also enter that within the app’s config. For the example above you should use [http://192.168.1.100](http://192.168.1.100) as connection link in Homey app ---

I’ve got here a Homey Pro 2019 vs 10.0.2 and ZATZ app vs 0.7.3 . I did install 4 devices from the ZTATZ app and they are working fine. But I cannot change any settings (like change the status indicator or even change zone) of these devices in the mobile app anymore (did work before): I get an error: device: should be string (#/properties/note/type). I can change zone in the homey.app webinterface though. Trying to install new devices from the ztatz app result in a screen saying :" Er zijn geen nieuwe apparaten gevonden". This did work before using the same url: [http://192.168.178.12](http://192.168.178.12) . Url has not changed (the devices installed before still work). Does anyone have any idea? Thanks ---

One hour later ZTATZ has been updated to 0.7.4. (what a conincidence, wow). But nevertheless, it is still not working. ---

Problems solved: 1. The error when trying to change status indicator or zone in the homey mobile app is a bug in homey 10.0.2 probably. When you first add a note at the botttom of the device property screen, you can save all the changes:[device-should-be-string](https://community.homey.app/t/error-device-should-be-string/92117) 2. Not being able to install new device from ZATZ app: I tried to install the same device twice (in order to get two different statuslines). YOU CANNOT install the same device twice!! Thanks Stefan ---

Hi Stefan, Will there be any chance that you will update the app for the new energy dashboard? ---

Hi Stefan, Thanks for reply! That seems to be the issue and if possible can you also implement the water usage for the dashboard? Will there otherwise be a test future to help?
