I have the G4 pro (non Poe, now discontinued) which still supports a regular chine and power supply.
The chimes are Honeywell. One chime is hardwired to the transformer and doorbell to create the initial ding-dong in the basement, then the other Honeywell chimes are all paired to that basement chime via their proprietary wireless, so they start sounding too.
Hmm gotta admit I haven't really touched it since I installed it.
I am running it on POE though and no one has complained about heat. In FL, so also pretty hot here
So I went and touched it after I last posted. It's definitely warm on the sides and I wouldn't want to touch it long but I'm also not too worried about it for a quick button press.
I imagine with the wifi radio off it'd use less power so there's that
I have been running the UniFi G4 Doorbell Pro (PoE version) for about a year and a half now and wanted to share some real-world impressions. It has been through two North Dakota winters with subzero temperatures, snow, and plenty of dust storms before the fields start to grow again, and it still works like new.
A few things that have stood out over time:
* Reliability**:** I have not missed a single motion event or notification since switching from Ring. With 24/7 recording to my UniFi Dream Machine SE, it is impossible to miss an event.
* Cold weather performance: Being PoE powered makes a huge difference. There are no battery issues or wake-up delays, and it has not turned into a frozen "dumb" doorbell like my old Ring did every January and February. A few times it got colder than the listed temperature range, and it continued working perfectly.
* LCD screen customization: You can set custom messages or animations through the UniFi Protect app, and Home Assistant adds even more control.
* Home Assistant integration: The Protect integration adds entities for motion, button presses, and package detection. It is solid. Setting up an API key in UniFi OS and adding it to Home Assistant was simple, and once it is done the entities just work.
* Build quality: Still looks new after 18 months. The button has not yellowed, the camera lens is clear, and the audio quality is still excellent.
There was only one small hiccup where the visitor tone was garbled once, but a reboot fixed it immediately.
If you already use UniFi Protect, this doorbell feels like a natural fit. There are no subscription fees, full local control, and tight integration with Home Assistant for automations and notifications.
I wrote a full post that includes screenshots, YAML examples, and a few of my automations for anyone who wants to see more details or setup steps: [https://chrishansen.tech/posts/unifi\_g4\_doorbell\_pro\_review/](https://chrishansen.tech/posts/unifi_g4_doorbell_pro_review/)
They don't make a wifi version of the *G6* doorbells. (yet?)
The *G4* version comes two ways -- PoE or [wifi](https://store.ui.com/us/en/category/cameras-doorbells/collections/pro-store-doorbells-chimes/products/uvc-g4-doorbell-pro), where the latter takes power from either USB-C or the 16-24v doorbell circuit.
I suspect that the G4 wifi doorbells are discontinued will never come back in stock. Just a guess, but I wouldn't hold your breath. I further guess that once Unifi sells out their current stock of the G4 PoE, that one's gone too.
That said, you might be able to use your existing two-wire doorbell wiring along with the [2-wire retrofit extender](https://store.ui.com/us/en/category/accessories-poe-power/products/uacc-retrofit-poe-2wire) to get PoE to the doorbell. You'll need somewhere to mount the adapter near the door. If you can make all that work, then you've got a green light for one of the newer PoE doorbells. (Or the G4 PoE, which is still in stock, if you prefer that.)
EDIT: Shit, I just realized that the PoE version *can't* ring a traditional chime. 🤦🏻♂️ Ignore the following unless you want to just do the [wifi version](https://store.ui.com/us/en/category/cameras-doorbells/collections/pro-store-doorbells-chimes/products/uvc-g4-doorbell-pro?variant=uvc-g4-doorbell-pro-us), which is sold out and very hard tofind.
The [G4 Doorbell Pro PoE](https://store.ui.com/us/en/category/cameras-doorbells/collections/pro-store-doorbells-chimes/products/uvc-g4-doorbell-pro-poe-kit?variant=uvc-g4-doorbell-pro-poe-kit) is probably what you want. It works with traditional electromechanical chimes. If you want it to ring two chimes, there is a wiring diagram to follow. Just expand the section on this page that corresponds to your situation: [https://help.ui.com/hc/en-us/articles/4999240734103-UniFi-Protect-Set-Up-Your-Doorbell](https://help.ui.com/hc/en-us/articles/4999240734103-UniFi-Protect-Set-Up-Your-Doorbell) (I'm guessing you want "One G4 Doorbell Pro, One Transformer and Two Internal Relay Chimes").
Unfortunately they only sell it in a kit with a PoE chime, but you don't have to *use* that chime. You could potentially sell it (or wire it somewhere you do have PoE and then just have *three* chimes).
They have the WiFi versions of the previous generation:

Honestly though, the way doorbells powered by standard 2-wire have to technically work makes them problematic at best. They have a battery or capacitor that powers the unit briefly when the button is pressed. This allows them to disconnect themselves from power so it can then short the power wires (so a mechanical doorbell will ring). If part of that process fails or the battery/capacitor is getting old, the unit will go offline when someone presses the doorbell. It's a pain to run Ethernet to most front doors, but you'll also end up with something more reliable going forward.
The reason I got a Pro was simply the higher resolution camera. Everything else was “whatever” in my mind. It does have a pretty great image as long as you don’t care about it being taller than it is wide.
