I see peaks to ~68 degrees ☹ ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/1/9100336545a951c95186514a26ff1e0e626df74b.png) Does anyone see this as a concern? Context: around 50 devices Zwave/Zigbee/IP, around 20 advanced flows. These peaks happen several times per day, sometimes when Homey reboots (like in this picture), but also without apparent reason at random times. Even if I am not at home and no ‘movement’ happens/load is caused by users… ---

Thats not that hot, those chips can run 80c all day long. It could be that the peaks are when homey update’s an app or makes a backup or something. ---

Hm…I have power supply on 5.2V and with original cable it still undervolts… after I choose another cable, now it’s fine, proved by 3 weeks of heavy loads… so I wonder, is it with cable or just Power supply ? ---

No problem here with the original cable, but to get a 5.2 volt supply working i made a small change to the adapter and ethernet dongle. Maybe the deleted usb-c connector is enough to compensate for the longer original cable😂 ![IMG_2951](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/6/c68ad9b40a4099269dfe3136c637636c56a2ac1c.jpeg) ---

Did you try a shorter usb cable, longer usb cables (especially the cheap ones) can have quite a large voltage drop. ---

Well, using it for more than 2 days now. Voltage seems to have dropped since using the new power supply, altough it still touches 1,5GHz on top in the hourly graph. In the long-time graph it seems not to, as you can see in my earlier post. ---

Like @Sharkys and @Glenn_Seegers I bought a shorter usb C cable ( Ugreen usb C power delivery) which is 50cm, the original usb C is probably to long. Now my undervoltagealarm occured is staying away. ---

I did not read anywhere if it’s different on a Pro 2023, but @ Homey Pro 201x the Insights graphs get compressed over time, to save diskspace. This also means **(high) peak values dissapear over time**. In other words, over time less and less measure points get stored, and the graph shows more and more “rounded” values.
