In theorie it should work. Homey Pro 2016 doesn’t have USB C though, so you’ll need an unusual cable for the usb C connector on the adapter to USB mini connector on Homey Pro (early 2016). ---

Didn’t even think about the old connector. I might use it as an spare charger instead. 😀 ---

I have only just learnt about this issue after searching about an unrelated other issue. I bought my Homey Pro (2023) in February of this year, 2024 from Amazon in the UK and it seems the power supply has not been updated since this issue was first identified? Really disappointing to learn that the performance of my Homey has been nerfed for the past sevon months. This could have been the root cause of other issues that I have spent money to rectify when it comes to wifi/zigbee signal stretch in my fairly modest 3 bed end of terrace house, with a fairly small number of devices, compared to other users on here. Is the Rasberry Pi 15w power supply still the one recommended when using the Ethernet Adapter? ![Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/4/14c0f93e3551d3f4a50f316ca2b8db619a5e5aa6.png) This is the one I have and it’s still on sale!!! For clarity I’m also using the official Homey Pro ethernet adapter. I felt wanted to support Homey a bit more at the time I bought it, as I was initially happy with the product. This development is a bit concerning, however. I wonder if it’s an isolated incident affecting only UK customers? > **[UK Power Adapter for Homey Pro (Early 2023) | Homey Store](https://homey.app/en-gb/store/product/hy0031/)** > > Power adapter for Homey Pro (Early 2023) with plug-type G ---

[That power unit](https://homey.app/en-gb/store/product/hy0031/) is fine. It should deliver _ **5.2V** _ and it does, according to this : ![1000035271](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/1/41828b536f811376682774d3a0b13c32a3791da0.jpeg) When you still happen to have the original shipped power unit, which delivers 5.0V, it could cause performance drops when using an ethernet adapter. Athom communicated the issues with the first batch of power units, and offered to have it replaced by a 5.2V model, free of charge.

I am starting to be desperate and really lose patience on mine. Support told me to change my adapter, I changed it three times. Then I got tired, I purchased the Raspeberry pi power adapter that was advised here but I am still getting random disconnection due to the power… then support sent me a new adapter and it’s worse than with the raspberry pi power adapter… what to do? ![IMG_0326](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/7/87a32e577cf43716cd7f6a607c071722ebe8d24c.jpeg) ---

> [@cloudpulse\_01](#): > > I am starting to be desperate and really lose patience on mine. What cable where you using and did you also change it? Have you maybe bend the cable to put it away? Do you have a Ethernet adapter in between? What type of homey is it and when did you buy it, what that one of the first Homey Pro 2023’s or recent? ---

I removed the ethernet adapter to make sure it does not cause issues. It’s the Homey Pro (Early 2023) purchased in October 2025. I have the best stability with the Raspberry Pi Official 4 Power Adapter but still it fails at least once a day.

Could you please guys check my support request 146042 @Emile @Doekse ? I opened the ticket 6 days ago and I don’t have any answer. Also my Homey has been disconnecting almost every day since October and I’m left without solutions… [Previous page](https://community.homey.app/t/power-supply-can-cause-slow-homey-pro-2023/78279.md?page=7)
