Hi, I am experiencing issues with Homey Pro (Homey Pro (Early 2019)) since several weeks. It keeps going offline after some time. After rebooting (pulling plug and then reconnecting to power) it works, then after some days it will again go offline. Can someone please help me to fix this? It’s not funny to not have the coffee machine working in the morning (because the power plug didn’t start since Homey was offline).
First advice with all these “unstable” issues is replace the power plug.
Power plugs degrade by age and drop below 5volts.
I’ve tried different plugs, even connected the cable to a USB power hub today. No change. It will work without issues for 1-2 days, then starts being unresponsive again.
Can you check Memory or CPU usage ? Sounds a bit like it needs to restart fresh after a couple of days.
If so, a normal restarts instead or a PTP should work also.
If a normal restart doesn’t work it probably is something hardware related..
I’ll try the restarting but this just started recently - it was never an issue in the previous years! Very odd, and probably not the way it was designed to work.
You say “goes offline” . What exactly do you mean by that?
Is it unreachable via the app and none of the automations or switches etc work anymore or is it unreachable but automations are still working?
Unreachable via App and none of the automations work anymore.
You probably added devices and apps in these years ? Or at least updated them… but could still be a hardware issue…
Certainly yes - shouldn’t the system be dealing with memory management?!
Up to a point, somewere you’ll meet physical boundaries…
Can you ping Homey? To check if it’s really offline, or if it’s the “app thinks Homey is offline” bug.
This is a great network tool with ping aboard:
My Homey Pro Early 2023 has the same issue, but not sure that it’s really networking related. The whole system seems to freeze for a few minutes. My (Zigbee) buttons don’t trigger the flows they should, no ring is flashing (ruling out reboots), bridge ring is red (because it can’t reach Homey Pro) and the Pro can’t be pinged from the internal network (I have Uptime Kuma running for this).
Also, it happens at random, so it can’t be caused by a bad flow that chokes the CPU.
I’ve tested several power cables and chargers, even a mad expensive 100w Apple USB-C charger. To rule out instability.
This has been going on since I bought the 2023 Pro + Bridge as a replacement for my trusty 2019 Pro that never had these issues. Athom told me to just factory reset the new Pro and start all over with my smart home… real solid advice. Although I start to feel ready to indeed start over, but that involves selling the Homey stuff and opting for alternatives… such a shame because I always like the appeal of Homey, but my recent hardware experience is utter rubbish.
That is becouse you have to much end device on zigbee you need routers en then end device i did have that problem now solve i use less zigbee device en for offline homey could be the wifi i did have ziggo en everytime he disconnecting changed it en all now all oke no problem anymore
Use unifi best wifi system i have that now at home first i have ziggo en everytime disconnecting via wifi my device en my bridge now that i have unifi never disconnecting anymore
I know one thing you can start with: dump the Apple charger and use or buy the cheaper Homey original adapter.
Second thing: use the original USB-C cables or use very good ones.
In most cases only the original power supply gives enough power. Very few other USB-C chargers give Homey the voltage that is required.
-
Required Voltage: ~5.2V (especially with the optional Ethernet adapter).
-
Power Delivery Protocol: The Homey Pro does not use advanced USB-C Power Delivery (PD) protocols to negotiate higher voltages (like 9V, 15V, or 20V); it strictly needs a consistent 5.2V input.
Thanks for the suggestion. But the reason I switched to the Apple charger is because I did use the original Homey charger and cable at first (the correct model number), but got crashes that might or might not be related to the power source. The most stable power brick I could think of was an Apple one (not the ones from iPhones/iPads, but a beefier Macbook Pro one). Also, I don’t see any weird spikes in the undervoltage graph.
Now, I don’t use the Ethernet adapter. But if I have to throw more money at a functioning smart home, it’s not going towards an attempt to fix the Homey. Having non-functional buttons is a tough sell at home, seriously hurting the WAF… 
Kind of in the same boat. New Homey Pro using supplied power block and cable. Two apps installed - Lutron Caseta and Samsung Q-series soundbar. Only 4 devices.
Homey Pro goes offline and random times. Runs fine for 2 days maybe, then suddenly non-responsive - no ping returns, app says offline. LED ring is still breathing though, and Unifi console still show radio connected (5GHz), just zero connectivity. This feels like a HW issue
It’s an odd bug since years.
In short, Homey needs oldskool wifi.
- Create a separate 2.4GHz SSID and connect Homey with it
- keep at least 2m distance between Homey and a wifi antenna (router/Access Point)
- When you use AP’s:
-
- prevent Homey from hopping (MAC filtering/ maybe even fiddle with transmit power)
- Bind an IP address to it’s MAC for Homey and same for it’s connected devices @ DHCP server
Wow, OK. Already had an IoT ssid on a separate vlan, using 2.4GHz and 5Gz. Removed the 5GHz band from the IoT wifi network, bounced the AP Homey Pro was connected to at 5GHz to force a reconnect, and poof, showed right back.
Let’s see if it stays around …
