Hello, iI am wondering if anyone have similar experience to me and what have you done to fix it. I have Homey Pro 23. The web interface for Advanced flows is extremely slow. I am not talking about flow execution. For the flows I already have, flows trigger fine without any delay. But, I want to add new flows and its almost impossible to add a new flow. whenever i try to add new flow, web interface just freezes up. this happens when i try to edit existing advance flows too. i tried editing existing flows, creating new advanced flows and get the same result. Creating regular flows work fine without isses. I can control devices for web app fine without any issues.This has been intermmitently happening for a while. but now it is totally unusable. I had this issue on stable version and beta versions. some other troubleshooting I have done, - Try different laptops - Tried on home network and outside network - Reboot the Homey - Firmware upto date ![Screenshot 2026-04-20 180119](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/9/d97e59636f645d49e115c76ab135f317f9bded98.png) ![Screenshot 2026-04-20 180200](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/b/9b07a02b59d4ac348a18b1d4f018d1d7eb4aa6fa.png) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/3/03113f5e4f6c3f955686d6ec759d919e75333590.png) ---

Same here, for months now. Makes me want to give up on Homey.

I hope they take notice and fix it soon. Advanced flows is one of the reasons that made me switch to Homey Pro. ---

I am not seeing this. The advanced flow interface works instantaneous, no delays. For both my Homeys (2019 and 2023). (Maybe it is because I live very close the Athom headquarters? 😛 ) Kidding aside. Maybe you should open a ticket with Athom to investigate the issue. ---

I don’t notice any problems either? Have you tried using a different browser? I’m using a MacBook and Brave browser. ---

Wondering the same thing. From the thread @Peter_Kawa is linking to I see that he is using a browser I have never heard of on Android OS. Would be interesting to know which browser @Naresh_Kodali is using. For myself I am using Safari (Mac OS) and Edge or Chrome on Windows without issues. ---

When you read a few more older posts, you’ll find out I’ve tried almost every available browser for Android. Also Windows OS with Edge and such. I’ve no Apple stuff to test anything. ---

So browser is probably not the issue then. Don’t want to “repeat” the other thread you referred to here. But did you try accessing Advanced Flows from an other location or internet connection? ---

I normally use google chrome on Windows machine to access. I have similar results with Edge as well. Never thought of trying safari. I will fire up my old macbook and try. I tried multiple laptops inside and outside my home network. I thought may be its related to available RAM on my homey pro. I used to have more apps and only 100 Mb RAM free out of 2GB. Thinking this is slowing the web app, i removed some of my apps to free up space. Now i have 300Mb left. Little bit better now i think but still not usable. ---

I don’t have this issue on my Homey Pro 2019 (FW 12.7.1). I think this would be related to the RAM that the browser tab uses. The Homey web app loads all devices, Flows and Flow cards in memory when you open the Flow page instead of lazy-loading (which almost every website uses nowadays) ---

What a strange issue. I do not have this issue on my homey 2023. I use chrome on windows11 laptop. I have a heavy loaded homey, modded with 8GB memory. The homey uses 2.6 GB. But before and after modding I did not face this issue. Only with extremely big advanced flows it was impossible to add new cards.. Loading dashboards did not perform well last few months, but this is resolved with the latest firmware. Somehow this should be figured out. Could the modem/router cause problems? I just use the standard kpn box14. @Peter_Kawa I can give you my credentials to figure out if my homey has issues or not from your home… ---

I just uploaded a video of whats happening. in the video, if you see cards dissapearing, its doing by itself. I am not pressing delete. you will see cards change from one to another by itself.

And what happens if you do not use the cloud but local login? **Homey Pro now supports direct local web access, allowing users to log in to the [Homey Web App](https://homey.app/nl-nl/news/local-users-voor-homey-pro/) via local network IP addresses**. This requires setting up Local Users under Family & Guests in the app, providing faster, cloud-independent control of your smart home, according to Homey’s official announcement. Could be a problem with the connection of your homey with the cloud somehow.. ---

Yay! A cause and a fix (for me) at last: Jeroen (Athom) did like to run some tests directly with my Homey, so after granting access, he found a strange phenomenon quite quick: in short: a device of an app caused flow cards to be created and removed non-stop and insanely quick, massively delaying everything else. Removal of that particular device solved the issues. I’ll discuss & run tests with the app developer to see what’s the exact cause. To find similar issues: With the web app in focus, start the browser console (F12 with Chrome) Tap “Network” Tap “Socket” Tap the _[socket.io](http://socket.io) …_ line to see generated data ![Screenshot from 2026-04-23 00-35-09](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/8/d850a627a7aed38ec0129cf1d4a514105b945a66.jpeg) ---

Thats good news. Finally! Is that related to a specific device model/brand in your case or would other users with the same device experience the same issue? If so, what device are we talking about? ---

I understand and I’ll keep you posted; to avoid possible “finger pointing” I’d like to discuss with the dev first. ---

@Peter_Kawa Thanks for the tip on where to look. I have the same issue as you, flow cards being created and deleted. In my case its my own Refoss energy Monitor App. I fixed the code in the app and pushed an update. Advanced flows are back to normal now. ---

> [@Peter\_Kawa](#): > > I’ll keep you posted So, in my case it appeared to be a problem with the “mode list” of the “fan” type device, as part of the [Home Assistant community app](https://homey.app/a/io.home-assistant.community/). Other device types don’t seem to be affected; With every update of the “fan” device, all related flow cards were re-created. This slows things down massively, when these updates occur every few seconds. Jeroen Wienk (Athom) spotted the continuous re-creation of flow cards (after he was allowed to access my Homey); With that information, developer Ronny found the culprit in the end, and pushed version 1.15.2 of the app, which solves the issue!! ![Screenshot_20260430_122924_Ecosia](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/5/8578e0d245e3bc31b1f3cbf06de141f0dec1e0cb.jpeg) [Next page](https://community.homey.app/t/extremely-slow-advance-flow-interface/154039.md?page=2)
