Did you ask a generative AI? I’d really like to give it a try to see. ---

No, I didn’t think of that at all, very good idea! ---

I see what you mean, what I find difficult is illustrating: - the presence of a human - a local network Without too many elements or text ^^ ---

Yes, yes, of course! But I think too much text kills the illustration. ---

Hello, if some of you are motivated, I have a first version that seems functional and sufficient for detecting devices on the network. We’ll deal with the other features at a later time. The docker image: `atrovato/gladys:lan-manager` As a reminder, this is a test image and may therefore harm your « production » environment, so it is recommended to back up your data before using the image, or to test the image on another device, in order not to impact your « stable » installation. The feature is not available via Gladys Plus at the moment; it will be as soon as everything has been validated. Thanks. ---

Thanks @AlexTrovato! Tested this morning: - I don’t really like the logo colors, especially in the services list; it clashes too much with a « default Visio (Microsoft) colors » vibe. The same logo in a darker color would work better, I think (compare with the orange of the Zigbee2MQTT logo or even the illustration for Xiaomi) - During the scan there is a big CPU spike up to 168% but only for a few seconds. I’m on a mini PC, no issues. On an RPi you’d need to check the behavior, even if it means slowing the scan to save CPU - I have at least x3 phones on a WiFi router + Freebox (WiFi disabled) and the scan only detected two MAC addresses. But since I have two routers that means I also have two IP allocations; I imagine the scan only works on the same network as Gladys. I’ll test with two other PCs turned on. In any case it would be good to remind users of the scan limitations when there are multiple networks. - The scan results display the detected MAC addresses, without other indications. My Freebox for instance shows the name advertised by the device — do you think that’s achievable (in v2)? Otherwise, as a fallback, do a manufacturer lookup from the MAC addresses? Thanks for developing this service — it’s going to be useful 😊 ---

And I would add that the interface is very simple to use and super clear. ---

Thanks for taking the time. > [@lmilcent](#): > > I don’t really like the colors of the logo Me neither, I did that quickly, but I also asked for a bit of help to create a new one. I tested AI, but I have trouble getting my point across 😕 > [@lmilcent](#): > > During the scan, there’s a big CPU spike to 168% Well, I tested on a real PC, not a Raspberry Pi, and I use a library that does the scan. I can always change it though. > [@lmilcent](#): > > I imagine that the scan only works on the same network as Gladys The scan runs on the networks where Gladys is present; all network interfaces are scanned (eth, wlan…). So if your devices aren’t on the same networks, indeed, I can’t do anything. > [@lmilcent](#): > > the scan results display the detected MAC addresses Strangely, I do get the device names (except for one). > [@lmilcent](#): > > Otherwise, as a fallback, do a lookup of the manufacturers from the MAC addresses? That’s doable 😃 Thanks again. ---

Hi! Tested and… When I click on ‹ save › nothing happens, nothing is added to the ‹ devices › list and nothing in the Gladys log… RPi2 32bit Sorry :⁠-⁠\ Edit: I’m lying, there is this in the log : `2023-01-15T11:42:54+0100 \u003cinfo\u003e lan-manager.scan.js:20 (LANManager.scan) LANManager discovers 31 devices` But no matter what I try, it won’t save anything… ---
