Aqara U200 Overview - Apple HomeKey Retrofit Smart Lock!
I Take it this would work best with a slam lock?
I’m afraid I’m not really sure what a slam lock is! The best place to check compatibility will be the Nuki website
Hello, thanks for the great review. A quick question, I plan to connect the floor sensor (as a check point for the underfloor hearing). I noticed in the Meross app that you have the option to choose either 1) air and floor sensor or 2) just a floor sensor. If I choose the option air and floor sensor, then which one would it use to control temperature as the room temperature is expected to be less than the floor?
I’m afraid I’m not sure as I don’t have underfloor heating. I’d drop Meross support an email as I’m sure they’ll be able to help
Great review, can you tell me how long the timers are within the meross app. I’ve a light with multiple modes and need a on/off interval of less than 5 seconds. Unfortunately both eve and HomeKit don’t allow this. Do you know if meross’s app does?
Hey, Meross is only minutes too. Have you looked at Siri Shortcuts? I know you can delay in seconds there so depending on how you want to trigger the plug that might work for you
Not the kickstarter packaging then. Release to the public must be imminent. Looking forward to further reviews from you.
Yeah, I believe it’s being properly released the start of July
Love the mxpx bass
How is it with ps5
I thought great, I’ve a thumb turn… then I saw there’s many different types arghhh. I do like how nuki is trying to make it as universal as possible. Thanks for the vid 👍🏻
Yeah and a lot of the brands Nuki do the adapters for I’ve not heard of before which is why Yale is a pretty safe bet
Very helpful video. Do you know of a keypad lock that doesn't have any wifi/bluetooth/app? Just a keypad lock.
I’m afraid not, sorry
Take a shot every time he says monita
Enjoy that hangover!
Thank you for your review . Can I unlock the lock remotely ?
Yes with the pro via WiFi in the Nuki app or in the Apple home app
@@MarksTechVlogs thank you . Are you aware maybe any common malfunction that will need human action can happen often ?
@@Raphaelch93 I've been using Nuki locks for about a year and a half and the only issue I've had was actually an issue with a faulty cylinder
Enjoying your videos, thanks for your efforts. I got my Nuki last week. It may not affect the overall sound level but optimizing the lock action means that it doesn't travel so much. For instance, change from 720 to 360 rotation. And optimize for the significantly reduced locking distance.
I like your kitty.
I'm so confused. Mine only came with one mounting bracket. :/
Which country are you in? From various videos the accessories vary depending on your location
@@MarksTechVlogs I’m in Australia. But I’m not sure where the lock was sourced from.
Ah, I’m guessing they only include one in Australia…maybe to do with lock types
@@MarksTechVlogs which isn’t that helpful if I need the other mounting plate. There’s also a video on their official RUclips for an adjustment plate but no mention of where or how to get it. It’s all incredibly confusing. I just want to install the device.
I’d drop switchbot support a message as I’m sure they’ll send one out. I think they even have a WhatsApp support which they usually reply pretty quickly to
Do you know what diameter the exhaust hose is? I know I need to order a longer one but dont know what size to order. Great video, I've brought one off of the back of this video. Cheers
Hey, it’s around 14-15 cm.
@@MarksTechVlogs thanks so much! Couldn’t find anything online about it.
its 4 chanel. Dies it save every chanel seperatly or is it all saved in one file?
Yes, 4 different clips
@@MarksTechVlogs okay good, thanks
Can you please tell me the height with lider? You said 92 mm but does that include the lidar section?
Yes it does
I have my devices set up and followed the home kit set up. I am unable to see it on the home screen but can find it as a hub only with the detectors. Have a missed a step?
Nope, it doesn’t appear as a block in the home app like a bulb does but if you go to the room and look across the top where you see sensors you should see a smoke sensor
@@MarksTechVlogs thank you, just keep seeing images even on the advertising that show on the home app and I was not seeing it that way. I have found them using your method though thanks
Thanks, I bought this because of your video and it’s pretty darn good. Loud, sure, but the noise is comforting to sleep to. Only question I have is how much does it cost to run? I’ve been putting it on for like 20 mins at a time but would like to sleep with it on when next week’s heatwave hits. Any experiential wisdom welcome 🙏
I was using it last night for a couple of hours and thanks to Octopus’ tracking it looks like it was only costing about 20p an hour but will keep checking as I use it this week some more!
@@MarksTechVlogs thanks, super helpful 🫡
Is this stereo compatible with a 2010 mk6 Golf?
I don’t know huge amounts about comparability but as long as you have space for a double din connector and can get the stereo wiring adapters then you should be able to use it with one
Hi - what electric underfloor heating mats are compatible with this thermostat?
I’m not sure with this one, Meross do one for underfloor heating so the spec might say amzn.to/4cymFMn
@@MarksTechVlogs thanks - Yes this is the one that I have purchased, but it doesn't say or recommend any compatible mats
I see, I don’t have underfloor heating and know nothing about it so I’m guessing the best thing to do will be to contact Meross support
If I've already chosen carplay device, how could I understand if it's going to fit my Smart 451 MHD? I'm pretty new to this kind of things so want to be sure before spending money? Stereo in question is Incar ARN-7710-6.
I can’t actually find a link to that stereo. Your best bet might be to look up the measurements of the Pioneer one I’ve linked in the description and see if the dimensions match the one you’re looking at
@@MarksTechVlogs Thanks for your answer!
I have a Chubb 5 Lever mortice lock. It doesn't have a handle and the keyhole isn't like one of those modern euro ones. Can I use an Ultion Nuki?
Probably not an ultion Nuki but I’d contact Nuki to see if it’s compatible…or even switchbot about their lock pro
Wow, this video is packed with useful info! Your clear explanations and thorough demo of the features really set this apart. I'm definitely getting these smoke detectors now
Very helpful video thanks!
I have since bought a new fingerprint lock and it's superb... Ruveno Weatherproof Smart Door Lock with Handle: Fingerprint
I am interested to know that if I dont want to use the hub how many phones can I connect to the Fingerbot at once? Can it only be paired with one device? I want to use it to push buttons on the garage remote fob and give bluetooth access to various colleagues.
I’m not sure if you can pair to multiple phones unless you have the app and same login on them but you can use it without the hub as long as you’re in Bluetooth range
tried to install this at the weekend, and found that it stops the door handle going all the way down and preventing from actually opening the door
as in the handle catches on the lock? That's interesting...I wonder if you can change the handle to one that sticks out more?
@@MarksTechVlogs yeah as the handle goes down, the box of the switchbot gets in the way. its probably has to be getting a new handle that has more of a gap between it and the door
Do you know of any smart multi locks that work with apples home key?
At the moment no but the Aqara U200 which is now due out in July should be compatible and have Apple home key. I will be reviewing one as soon as it’s out
Do you still need to life the handle to lock?
If it’s a multi point lock then yes
I already have A roborock S8. But would been even more fun with a small one swiping the tight spaces 😂
the fingerbot doesnt connect to alexa
It might be worth reaching out to them as it’s still listed as supported on their website
Purchase it here: geni.us/Dbz7zC - Save 40% until the 30th June with this code UGDZ2PJM
Hi Mark - really informative videos thank you! Like you I have a door which requires an extra little turn on the key to gain entry from outside. Does this mean that I would be forced to use the Nuki app to unlock my front door with HomeKit currently only supporting “locked” and “unlocked”?
The simple answer is yes… The more complicated answer is that if your door is locked then unlocking from the home app will also do that little extra turn but if all you need to do is that little extra turn then you’ll need to use the Niki app…I usually trigger that open from a Niki widget on my home screen The ‘open’ feature has actually been added to Matter 1.2 so at some point for the 4th gen Nuki locks it should make it into the Apple Home app but I have no idea when Apple will add it!
@@MarksTechVlogs gotcha - I wonder whether this is what’s holding back Nuki from offering Apple homekey support :( So in the meantime, if I understand correctly, if my door is fully locked, say when I come back from work, the lock will Auto Unlock using Bluetooth. But if I nip out to the car and shit the door behind me I use the app like you say.
@@stugedwards Yes that's right, I think it's to do with how Apple verify Homekey and at the moment there's no retrofit Homekey lock available however, the Aqara U200 is due out in July and does have Homekey so whether that will open up the door for Nuki to implement it will be interesting to see
@@MarksTechVlogs great - thanks for your help - much appreciated 👍🏻
Can this Dashcam be hucked up to a portable apple carplay android auto screen that has the capability of a reversing camera 🤔
I don’t think it can be as there’s no video out
For How many days internal 4GB Storage by recording the whole day?
is it adjustable as in moving it upwards and downwards?
No, only tilting
Thanks for the discount, looking forward to trying.
I’m still using it and think it’s great, hope you’re just as happy 😀
I have used Nuki 2 and 3 and also Yale Linus in several Holiday Rentals that I manage. I switched all of them to Switchbot, for several reasons : Price, Battery Life and Functions. Battery life is 50% better than Yale and 40% better than Nuki. The Mini Hub (I also have the Hub 2 in several houses is cheap and had a at least a 5 x longer range than the hubs from Nuki and Yale, which enables me to pair 3 locks in certain houses with 1 hub. Besides that in many Holiday Rentals the hub now also pilotes the airconditioning from a distance, which means big savings for the owners. In certain house I have lights at the entrance coupled to the switchbot, so that when the lock opens the door a light goes on as well. The Switchbot lock allows temporary codes which can be set for 15 minutes minimum and also unique codes that can be used only once. You mention that the Switchbot Pro Lock does not have that ? I will find that out tomorrow when I will install 4 of those for a new listing. The Switchbot helpdesk is super reactive and offer great service. I am sure that the functions of the old Switchbot lock will (soon) be available for the Pro Lock if that is not already the case. We use wifi for all our locks and Switchbot costs half the price of Nuki, offers more functions, and is sooo much quieter than the loud Nuki lock. The only thing for which Nuki is ‘’better’’ is that Nuki has integrations with more rental software companies than Switchbot. But I don’t use that functionnality, we welcome all our guests personnally and then let them choose their code for the duration of their stay until their check-out time. Switchbot also is more compatible with more keys and knobs than any other smartlock.
Awesome to hear about your setup, I do love the Switchbot lock Pro 😀
this monitor is perfect Ive js got it the other day nd have no complaints
I have the same one but my is hella slow idk why any help ?
@@Anonymous--123why slow wdym?
@@renjuh nvm my dumbass pluged the cabel in the wrong place this shit a NASA monitor 🔥🔥🔥
Hi, what does it not do that the previous mini does?
Essentially it’s just the addition of Matter support. There’s a handy table on this page comparing the old and new mini’s alongside the Hub 2 uk.switch-bot.com/products/switchbot-hub-mini-matter-enabled
I see some people in the Kickstarter program have received their U200s and yes Homekey is included. I’m looking forward to your review when you get one 😊
I think it's pretty loud
Hi. Useful vlog thank you. I have Apple phones but I have no idea what the apple HomeKit is that you refer to. Do I need a hub or apple tv or does this work on my phone? You mentioned having apple tv but is this necessary? Thanks.
Hey, so HomeKit is Apple’s name for devices that work/appear in the Home app on your iPhone. If you get the Ultion Nuki Plus which has WiFi built in you don’t need anything else for out of home access but if you get the base model then you’ll need something like a HomePod Mini or Apple TV which will act as a hub so you have out of home access
How to reset from account I get builder hand second
The person who sold it to you should have reset it from their account. You may need to get in touch with them
my door has a split spindle (door locks when u close it becasue the outside handledoesn't pull the lock back - they key does that
I think that's the same as mine although mine only has one actual spindle but even if the door is unlocked from the outside I still need to put the key in and give it an extra turn for it to open from the outside, is that the same as yours? If so either the Nuki or Switchbot Lock Pro would work
@@MarksTechVlogs yeah I need to put the key in to open it. One though is I need a lock with a keypad
You can get external keypads for both the Nuki and the Switchbot which go on the outside of your house
they say you need a gpu to run on 240hz is that true?, i have it on display selection
I’ve just double checked the AOC website and I think you’re right

Hi, is the Locks touch discontinued, I can't find it anywhere?
Yes, unfortunately they announced a couple of weeks ago they were filing for bankruptcy
Please tell me how to achieve those electrical connections, parts and tools to use.
The hard wiring is easy, you just need a small Philips screwdriver and the wires with the hard wire kit just wrap around the connectors and you tighten the screws. The manual has instructions for this too
@@MarksTechVlogs i mean the fork or rounded type connectors on your doorbell, I guess you need some kind of crimper to do that.
@@MarksTechVlogs 5:52 here
@@GabrielLuna81 The hard wire kit I got had the cable pre-crimp so I could wrap them round by hand with no extra tools
Could you add an extra one to your hot water?
I’m not sure if it would be compatible. Best to contact the company to check
