That one states it’s unavailable when I w ent to Amazon.Ca. I do like that it states Wyze in the description, but can it keep the battery charged? 500mA translates to 0.5A which may be adequate to “maintain” a good charge. I’m searching Amazon.Ca for a better option, especially if you have to really charge the battery in the doorbell if it drained a significant amount. You may have to pull the battery and charge it externally occasionally. It took several hours to charge the new duo battery using a 5V/1.0A wall outlet adapter. 18V provides more power output but the 500mA is basically providing a trickle charge. The duo battery is rated at 5V/0.8A(800mA) for input with an external usb c connection. The battery is a 6050-6200mAh rated battery and may not mean much to you.
Thanks…
Just spoke with the electrician and he said my placement of receptacles in the area of the door are bad, and he feels it will be easier to get to the box with a wired transformer which will also be more secure than a plug-in.
Therefore, would this one meet my needs…??
It should, yes. It or something like it should suffice, as long as the output meets your doorbell’s power input needs. For most of their wired doorbell models, Wyze’s official recommendation is a minimum of 16 VAC (Help Center articles usually say 16-24 VAC) / ≥10 VA, though for some reason (as I noted above) the Duo Cam Doorbell’s product page says “10-24V AC”.
That’s because those wires are for the side that you (or your electrician) would connect to your home’s higher-voltage AC wiring inside a junction box. You see three wires coming out that side and the other side (on that particular model, because it’s a tri-volt transformer) has three screw terminals that you could connect to for three different combinations of step-down voltage and power output. A single-voltage transformer would have two screw terminals instead.
The second product I listed above (via Amazon.ca) is a plug-in transformer. It also has screw terminals for attaching wire, but you don’t have to wire the higher-voltage side directly into a junction box in your home: Instead, you plug it in to an electrical outlet.
You would if that’s the route you choose. You’d connect your doorbell unit to the transformer with 2-conductor wire and plug the transformer into a convenient outlet.
No apology is necessary. If you don’t ask questions, then how do you learn? I come here to learn things, too. 
I think that’s probably your best course for a successful outcome with this.
Fitst of all, why are the transformers considerably more expensive in Canada Amazon than USA Amazon? Doesn’t make sense.
What does the electrician mean by placement is bad? Do the receptacles work? Do you keep your doors locked? Do you have anything else plugged into the receptacle closest to the door? Do you really have to worry about someone disconnecting a plug-in transformer? You don’t have to have the wire being exposed outside. Run it inside to the spot where you want to install the doorbell then drill your hole and have a direct connection to the doorbell. What box will be easier to get to and what the wiring run to the doorbell outside by the door?
I ask these questions and make comments because this doesn’t “pass the smell test” to me. It has the appearance of someone trying to make money. Ultimately, it’s your home and doorbell and the decision is yours. But if you go with transformer wired in your electrical panel to a breaker or a junction box away from the panel and a shared power source, get a single 16/20, 16/30 or 24/40 transformer, cheaper than the one you posted, I hope. If not, make sure the connection higher connection terminals are used.
@Crease - Once again we crossed paths while I was typing. I don’t understand the direction the electrician is trying to take @mfhumes if not for financial gain.
It makes sense to me, to a degree. $ 
≠ $ 
, and some of the prices I’ve seen @habib quote for Canadian products seem high when I’m in the U.S.-dollar mindset.
That’s one perspective. My perspective as a non-electrician, having had good experiences with electricians, is that they’re entitled to make a living in their chosen trade, and if a particular job is more involved or complex than what I feel comfortable doing myself, then I’d rather pay a professional to take on that liability. Based on the questions @mfhumes is asking and the opinions expressed, that’s the sense I’m getting here. If @mfhumes is expressing so much uncertainty about the DIY approach—and I genuinely think it’s to @mfhumes’s credit to spend time here and ask questions, because I think that demonstrates a willingness to learn—then maintaining the relationship with the electrician who’s already been contacted about the project seems the most likely way to produce a good outcome.
I really appreciate the value of Wyze products at their price points, and doing things myself when I can appeals to me, too, because I like the sense of satisfaction and accomplishment that comes with that, and I also like avoiding unnecessary expense. We’re not all cut out for every potential DIY project, though, and sometimes a higher financial cost up front is worth the cost in time and frustration later on.
Thanks folks… appreciate all of your assistance… and comments.
My questions likely reflect my lack of knowledge and understanding… and your patience has been noted…
I think the wiring challenge comes from all of the brick and cement around the door area… with no plugs very close… he said he’d rather go straight down to basement, after going up under the door frame to the doorbell… walls are all plaster/ lathe and snaking isn’t easy…
I know the guy pretty well and have a lot of faith in him…
Based on what I have read, asking for a
16-24 VAC) / ≥10 transformer at Home Depot should get the proper piece in my hand??
Btw… The $ diff is crazy, especially right now… exchange rate is about 40%
Cheers!!
Thanks for including the info on the home construction, clarifies what the electrician had as an obstacle. I may have inappropriately made a wrong assessment of the electrician’s intention without knowing the info you provided and your relationship with him. No offense perceived I hope.
Good luck with your installation. Now that the Wyze app update has been posted, I’ll be switching out my vdb.v2’s for duos this weekend.
@Crease - Your at length statement regarding @mfhumes consulting an electrician and my comments are acknowledged. Subsequent info provided by him about house construction would have been helpful earlier in the conversation exchanges.
I also am not a certified trained electrician, but having owned my house for almost 40 years, I’ve had my share of electrical diy’s from the basement to the attic and from panel new breakers up walls and out to new floodlights and attic fans. I would do solar today if doing again on the floodlights. Even replaced the fan motor on my furnace and wired in a timer control box for the hot water heater. I do understand the complexities of electrical projects and definitely agree the electrician is entitled to make a living for his/her work. It’s based on my knowledge from what I have learned that I offer advice and suggestions.
Btw, having traveled to Canada previously, but not in recent years, I failed to remember the nuance known as exchange rates.
Fmills1d…
I went to the Play Store to look for updated Wyze app… no could find…??
Michael
That’s important. I’m glad you have a relationship with someone you trust.
Just so we’re clear on the numbers and units:
- the 16-24 is measured in VAC (volts alternating current, the rating for the electric potential difference of the transformer’s output)
- the 10 is measured in VA (volt-amperes, the rating for the apparent power output of the transformer)
16-24 VAC / ≥ 10 VA is Wyze’s general recommendation for the power input to their wired doorbells. On the Video Doorbell v2 box that I have right here, they label it this way:
Power Input: AC16V/AC24V,≥10VA
You mentioned earlier in the topic that you’ll be sharing this with your electrician, and I imagine he’ll have no problem processing this information.
Neither am I, but I feel comfortable replacing outlets, switches, light fixtures, ceiling fans. I don’t have any experience snaking cable, but that’s something I’d be interested in learning if I had an application for it.
I’m guilty of making assumptions and try to be aware of my own biases, especially in situations where there are likely to be differences of opinion. I think we all just want @mfhumes to have a positive experience with this. 
Sometimes it takes a while for Google Play Store to show an update available. It’s finally offering Wyze app v3.2.6.592 to me. If you’re not seeing it but want the update, then you could try clearing the Google Play Store cache and hitting the Wyze app page again to see if that pulls down newer data for you. To make checking for updates more efficient (for the way I work, anyway), I use the My apps shortcut. Even using that, though, sometimes I have to swipe Google Play Store away and launch from the shortcut a second time for it to pull down the full list of available updates.
Crease, Fmills1d, and all…
You have been unbelievably helpful… and patient… I really do appreciate it
I have ordered the unit and expect delivery next week.
I will keep you posted on how things go.
Also, Thanks for that info on the update!!
@mfhumes - You are more than welcome. Kudos to the Forum for another “satisfied user”. Continue to reach out when needed or even chime in (pun intended) to offer insight to other users inquiries.
It’s finally offering Wyze app v3.2.6.592
Crease… after re-reading your post, I checked my current version of the app…
I have… and have had since d/l the app a few days ago, the updated version…
Ergo, I am not able to appreciate what benefits the updated version brought?
… but I am glad I have it…
They don’t seem to publish any sort of detailed change log, but the release announcement topic can sometimes be enlightening. I’ve disabled automatic updates for the Wyze app in Google Play Store and also for firmware updates for products that expose that as an option in settings. I use the notification options for the Forum and Wyze’s Discord server to let me know when a new app or firmware version is released, and then I track those topics for a week or so to see what problems are reported before I make a decision about whether or not to upgrade my own gear.
