I’ve pretty much given up at this point so I guess this is more a rant. Someone stole my original video doorbell that worked fine. I bought v.2 as an upgrade even though I hate that there isn’t. Plug in chime option (worst decision of all on upgrade wyze!). I’m not dumb, I can both follow instruction and most of the time troubleshoot and figure things out on my own. I HATE THIS DOORBELL! Wyze should apologize and refund anyone who bought it. After installing it per instructions, troubleshooting it, reading forums etc etc. and wasting countless hours trying to install the damn chime controller. Or NOT because it just clearly is garbage and doesn’t work. I said screw it, and just returned for a refund the v.2. Annoyed that I’m still without a doorbell I thought. Just buy v.1 again and be done with it. Today that arrived. Done this before. No problem. Tried to install it, and realized that now the power or wiring or something is screwed that went to the doorbell from the v.2 install and tada!!! Can’t power the v.1. AWESOME!! So now returning a v.1, the power to my doorbell is screwed up and no longer working and I’m left with the options of paying an electrician to come fix it for me and again buying yet another doorbell to install. OR giving wyze another 100 dollars plus shipping for the stupid pro doorbell because it uses battery power and guess what a plug in chime that should have never been removed from the other versions at all. My entire home is wyze ecosystem and I’ve been mostly happy with it. This doorbell fiasco has pissed me off to no end. DONT BUT V.2!! And shame on wyze for selling this crap knowing the chime controller problems a LOT of people are having but mostly for removing the simple basic plug in chime that could have bypassed all these problems from the get go!
I’m sorry to hear it isn’t working out for you very well.
It certainly would’ve been nice to have the existing chimes work with this new doorbell v2.
I have heard people say that the VDBv2 doesn’t work very well with transformers that are under 24 Volts. I guess it draws more power than the VDB v1.
I’m not recommending you try the VDBv2 again since you had problems.
If you still had it in your possession, I would’ve recommended hooking everything back up the way you had it before with the V1 and just using Google or Alexa speakers as chimes that will ring anywhere in the house instead. That’s what I do for one mine. It also still rings my phone, etc too.
For me, I see the mechanical chime as more of a bonus for those who have been begging for it (it’s been a highly requested feature since Wyze first launched a doorbell camera), rather than a requirement. At least that’s how I use it for one of mine (I have 2 of the new v2 VDB’s, one with a mechanical chime and one without it…as well as a v1 VDB and a couple VDB Pros). I didn’t want to use one of them with a mechanical chime and it worked pretty well without it.
Something else a lot of people do is simply bypass the original transformer (turn it off), and use a C-Wire adapter to connect directly to the doorbell wiring instead like one of these:

But that won’t work for a lot of people’s wiring situations.
Your caution makes me think that maybe I should go apply labels on my wires while I still remember which wire originally went to what in-case I ever need to undo or change my wiring in the future so I don’t get things mixed up.
I hope you’re able to figure out the wiring. I’m sorry to hear you had such a bad experience with this.
Maybe it is too late for the topic owner, but FWIW for the rest: I had issues with getting my doorbell-v2 to work with my existing older house chime as well, but Wyze online support was quite helpful, and they recommended me to have a different wiring of the transformer than that in the original instructions, and that WORKED!
I’ve been using it happily since then.
I can share the wiring photos if needed by anyone.
Oh, Cool! You didn’t have to get a different transformer or anything? I heard other people fixed it by doing that. But they were able to give you alternative wiring instructions and that fixed it for you? I am interested to hear what they had you do differently so I can better answer other people in the future when I tell them support might be able to resolve the issue for them with alternate wiring instructions.
Yes, that was definitely how it was solved for me. I went ahead and found the transcript of that support I received from the customer support agent for you, this was the message that helped me fix the issue:
“Could we try to alternate the wiring for Wyze Video Doorbell v2? You may follow this link https://support.wyze.com/hc/en-us/articles/19994563596699-Alternate-wiring-instructions-for-Wyze-Video-Doorbell-v2”
Hope it helps
Thank you! I will happily share that with other people in the future.
The Wyze battery doorbell camera V2 is the biggest piece of junk. It goes offline multiple times per day. Firmware says up to date but only once in awhile does the restart option work. I have had to remove and add the device at least 4 times to get it back in line. My router which says good connection is just in the other side if the wall from the doorbell and near the window
This is absolutely not my experience. Works quite well and stays online.
Welcome to the Forum, @tddybear2203! 
Whenever I see reports of issues like this, one of the first places my mind goes is power issues related to the transformer, chime, and wiring in the rest of the system, so that’s where I’d tend to focus my initial troubleshooting efforts, especially if other Wyze and other vendors’ IoT devices seem to be working well and have adequate signals on your Wi-Fi network.
While the alternate wiring instructions describe a second way to connect the Chime Controller (not the transformer) to the chime, and they may work well for some users, I found that wiring scheme to be less than ideal when Wyze Support suggested it and I tried it on my own doorbell chime. When I had the Chime Controller wired according to those instructions, my home’s built-in mechanical chime exhibited a persistent buzz/hum, and Wyze Support told me that’s normal when Chime Controller is wired that way. That was unacceptable to me, so I did further independent testing/troubleshooting and discovered that my chime had been wired incorrectly before I ever moved into this home: The house wire attached to the TRANS terminal was actually from the doorbell button location, and the house wire attached to the FRONT terminal was actually from the transformer. Once I discovered that and corrected the wiring error, I was able to use the Chime Controller with the standard wiring scheme, and that resolved all my chiming issues.
That’s why I always recommend having a multimeter, understanding how to use it, and doing one’s own testing to assure that everything is connected correctly and operating as expected.
My standard disclaimer: 
I am not an electrician.
Sorry to hear this. I have had my wired v2 doorbell for over 2 years now and have zero regrets about switching from my previous Ring Pro. It works fine with my home doorbell chime. I had no issues installing any of it.
This is not to rub it in, just to say there are plenty of satisfied owners and if I were you I would not give up. As others here have mentioned, I would replace your transformer. You can get a modern doorbell transformer at Lowes or Home Depot for $20 and swap it out in minutes.
