I have my Homey for around 16 days now and it keeps rebooting on random moments. I can’t seem to figure out what is going on. Its currently running the latest firmware 12.10.0, its connected to wifi (3 meters away from router), I’m using the Homey dongle and it has a couple of 433, RTS and Zigbee devices (Ikea/Agara) connected next to my Enphase Gateway and Inverters.
Is there a way to get some more light on this situation, is there a log that can be looked into or an app that can log stuff? (and how to set it up) As I currently have no clue how to fix it.
This is typical for either a bad power supply, a bad power cable, or both. The ones you get with Homey are notoriously bad in quality, so try replacing them.
When Homey pro reboots in normally doesn’t add an entry to the timeline, so I assume the timeline entries are from a flow you made to get an clearer picture about this issue? One that triggers on the ‘Homey has started’ when flow card?
If that is not the case, check you’re flows there might be one that issues the reboot. In the past even I had forgotten I made such a flow under specific conditions.
Yes, that’s is correct, as Homey does not notify me about a reboot normally. Indeed, I created a flow that triggers the timeline entry after a compleet reboot with a notification to me as owner. This to give more insight in the frequency and to find out if there are any memory or CPU peaks, but nothing turns up there if I analyse the apps afterwards (but it might not be visible in the graphs if Homey crashes right away)
@robertklep I can try that. Is it just unstable or what is it? As the required amps is 2A and the transformer should be able to deliver 3A. Recommend same specs or would you recommend oversizing? (Because they are low quality or does the Homey actually require more power?)
I was going to say that the output should be 5.2V, not 5V, but the official charger that came with my HP2026 states 5V, 3A. A charger that can deliver more A means it probably outputs a more stable voltage when it comes near to its maximum current, but I think the original chargers are just of bad quality, so they drop the voltage too quickly, causing issues with Homey.
Specs changed between the 2023 and 2026 model. Also refer to this post and Athom’s response below it:
The 2023 model indeed needs the 5.2V power adapter.
Though after one and a half year of use, I am getting very incidental undervoltage situations. Typically after a firmware upgrade.
@robertklep Interesting, these are the specs of the adapter that came with the box of my 2023 model. If 5.2V with 3 Amps is required, this one is by definition underpowered.
Looks exactly like the one I got with my HP2026 (well, not exactly the HP2026, but the Special Edition).
According to answers on the post that @SunBeech has linked to, 5V should be okay, but given that your Homey is only 16 days old and it’s rebooting randomly, I would suggest contacting Athom and asking about this.
We originally switched to a 5.2 V / 2.1 A adapter because early CM4 revisions used a less stable power-delivery circuit. Although this was improved in later CM4 revisions, we continued shipping the 5.2 V adapters for consistency.
Since all CM4 units currently shipped now use the revised power-delivery circuit, we have moved to a 5 V / 3 A adapter.
