It’s an issue with the new version power plug with device ID: 512 as documented in this post > [@Neo coolcam powerplug](https://community.homey.app/t/neo-coolcam-powerplug/10599/40): > > Neo confirmed it was a firmware issue and the home assistant users also did a thorough deep dive into it and also came to the same conclusion When you look at the raw zwave data on the developers pages of you’re homey you will also see the raw wrong data about the usage come in straight from the plug . Aka the plug it’s software is failure probably the issue is with the firmware from Neo as documented here on the settings that we can change to at least get it somewhat working with homey. But the value still shows negative which > [@Neo coolcam powerplug](https://community.homey.app/t/neo-coolcam-powerplug/10599/25): > > At the moment, only the settings of a V1 Coolcam plug can be changed via the advanced settings in the mobile Homey app. For a new V2 plug this won’t work because the parameter numbering is incorrect. (I understood the app developer, Marco Ruiter, is currently working on this and it will be possible to change settings for all plugs again in a coming update of the Coolcam app.) For now, if you want to change a setting of the new V2 plug, you will have to do this manually. You need the values as… Not sure if you as a seller can ask Neo Coolcam engineers to look into it with @MarcoRuiter who developed the app for Homey ---

Yes, all users have this on the V2 version of the plug . Its a firmware bug also confirmed a couple of months ago by Neo Coolcam thru the chat on their site. Domoticz and HomeAssistant users also confirmed this. The bug is only in the EU plugs - also confirmed and tested by multiple users on multiple controllers. Direct connection thru a AEOTEC Zwave stick console communication log also shows the plug reporting the -21xxxxxxx values in its com. For the record the V1 plugs dont have this problem ---

I think you better chase the official Neo Coolcam manufacturer who’s plugs you are selling. They should be able to solve this because it’s in their firmware. I had contact with the official Coolcam store on Ali, but they didn’t come up with any solution. ---

I had this issue with another brand of smart plugs. I found that (in my case) it was due to a crappy plugin adapter. (it was an IKEA adapter for a small light platform for a glass statuette) The adapter even was warm when the light was switched off. So it was poorly created. I currently have the same adapter between my washer (to get a push message when it’s done, and now it works fine), so if it’s the same issue, it may be caused by the type of equipment your trying to switch. Try something that uses more power? Then you can rule out Homey and move to the vendor. ---

the issue is verified on different platforms, so it is a NEO problem to solve 😉 ---

I just bought (around november 11th) four of these plugs on ali and i have them running for 4 days. They still have the same issues. They also have a crappy range, where the version 1 has a range around 5 meter, the version 2 has no more than 3 meters. The guy from the official coolcamstore on ali told me that homey was not fully compatible with version 2.
