Ok, so removed, reset and added within cm of the hub. Still the same readings -32,768 luminance and -1 UV ---

@DirkG: There are two different posters in here. @jumpingjimmyfaz has the problem with the strange values, probably caused by the firmware of the multisensor. @HarmJ has the problem that the UV meter does not update itโ€™s value. @HarmJ: The limit voor the UVI sensor is set to 2 as default. So if the sensor is inside and it is cloudy outside you wonโ€™t see changes. I got readings from it in the past when it was sunny outside I read you tried with an UV light, but I am not sure the sensor responds to that light. ---

My problem doesnt matter. I can live with that haha. I only thought it maybe had to do something with the original poster problem ๐Ÿ˜‰ ---

Hi all, I understand that I am unable to update the firmware on Aeotec devices (and other devices) Over The Air (OTA). I hope this is correct and would therefore, need to purchase a suitable Z-Wave USB Stick. I am looking to purchase an Aeotec Z-Stick 7 (when available) unless anyone can recommend a better alternative which is cost effective and easy to use. Any help would be greatly appreciated to try to get these misreadings resolved. ---

That is correct. Any zwave stick will do the trick. I used [Zwave.me](http://Zwave.me) USB to update the firmware. Are you located in the Netherlands maybe you can borrow mine ๐Ÿ˜‰ ---

Iโ€™m experiencing the same issue with my Multisensor too ๐Ÿ˜‚ can I borrow your z-wave stick to fix my issue as well please? [Previous page](https://community.homey.app/t/aeotec-multisensor-6-strange-minus-readings-on-luminence-and-uv/54486.md?page=1)
