After some back and forth with the product team, you can use the API. Once you use that call, it will wake up the device and send the latest info to the gateway so basically its a call for Refresh Data. https://developer.cisco.com/meraki/api-v1/create-device-sensor-command/

The device itself, if nothing is happening, will report to the gateway (MV or MR) every 20 minutes and then sends that data to dashboard. The ONLY time it triggers a response or update to the gateway, is if an Alert Profile threshold has been crossed. For instance, if you set an Alert Threshold of 70 deg F, either higher or lower, if it drops below 70 deg F, then it updates the Gateway and sends an alert. I would bet that via MQTT you would see this data as well. For a MT15, I think, and I am hypothesizing here, that you could be in luck because there is an overall alert called Air Quality which has a metric of 0-100. Its a factor of all elements/sensors on the MT15 including Temperature, Humidity, TVOC, PM25, CO2, and Ambient Noise. I would play with seeing what happens when you set that threshold to report if it is below say 95. See if you get multiple alerts that change over a period of time (within 20 minutes) or does it only report once? I would then take this a step further, Try adding multiple Alert Profiles for like Below 98, Below 96, Below 94, Below 92, Below 90, and etc. Could also do the other which would be Above 96, Above 94, etc. It could yield as an option closer to what you are trying to do or it could be extremely noisy. I have not played with the MT15 and MQTT in awhile since My HA server went down a couple years ago, but since I know the 20m doesn't appear to be something that can change, play around with the options available to you to see if that can yield a closer solution.

This answer is correct. Not possible. Happy to have more conversations around this if you need. good read to check out: https://documentation.meraki.com/General_Administration/Support/Information_for_Cisco_Meraki_for_Government_users

This is accurate. There is no IP Stack on the MT sensors so the only way the communicate to the dashboard is through the gateway they connect to (MV or MR). The ethernet option is STRICTLY and only PoE today.

Without going to each camera in your dashbard individually, your best option is doing the API like mlefebvre suggested with that many cameras. I would highly recommend maybe using TAGS on the cameras that have it because you are right, there is no way currently to show a list of cameras with MV Sense (or even MQTT) enabled in dashboard today. Hoping we can do something in the Camera List View where you currently can filter on MV Cloud Archive and which cameras have it enabled or not to atleast give some sort of filtering view. I have brought this up with the product team.

Larry_Woods · ‎Oct 10 2023

Not currently but it should be something we are bringing as a feature in the future.

Link is broken and requires ')' at the end of it Han

Yes there is a difference @EricWenger . MV has the possibility of having up from 1 to 3 licenses depending on your needs. 1. MV License in general is required for management, viewing, support, warranty, and all the things really to get you going. So with every MV hardware you would need to get a MV license to start. https://documentation.meraki.com/General_Administration/Licensing/Meraki_Licensing_FAQs 2. MV Cloud Archive - OPTIONAL - and is there if you wish to store video in the cloud. https://documentation.meraki.com/MV/Initial_Configuration/MV_Cloud_Archive 3. MV Sense - OPTIONAL - all Organizations come with 10 free MV Sense licenses and this is really around going deep on your analytics for what the MV cameras can offer with customization and a variety of machine learning applications . https://meraki.cisco.com/lib/pdf/meraki_datasheet_mv_sense.pdf So you need to make sure you have #1 to start and get you going and the other 2 are completely optional.

Would check this out. https://wirelesslywired.com/2022/06/06/meraki-mt-mqtt-node-red-amp-home-assistant-auto-discovery/ A lot of us here are Cisco Meraki have been playing with Home Assistant with NodeRed and man its been pretty fun building things out. That blog was written by @WirelesslyWired and its a fantastic guide on getting started if you really want to get dirty with Home Automation things.

Larry_Woods · ‎Aug 17 2023

Will pass this on to the product team for sure. Thanks for the feedback.

Larry_Woods · ‎Aug 16 2023

That hasn't really come up because the MT requires a 'gateway' to get back to the dashboard for communications. There are no IP stacks built into MT so it uses it's encrypted connecttion to the gateway and then the gateway handles all connectivity to the dashboard. I would recommend buying a less expensive access point (disabling all SSID radios and JUST have it be for the MT) or use less expensive cameras to handle this if you really only require MT to be accessible for readings at this point. Will pass this use cas along because thinking outside of the box as to other ways for MT to connect probably isn't just beneficial to you. MT only admins are in the works but we are still working out the details before we can announce a launch for something like this.

Larry_Woods · ‎Jul 11 2023

So sensors require to be put in the same network as the gateway which would be either MR or MV. As of right now, we do not have a way to do finite admin permissions for Sensors only like we do for Cameras. This is something we have been working on for awhile but because fo the administration hierarchy in Dashboard, it is extremely challenging to strip this down. Your options today would be to give the user READ-ONLY Network access or put the Sensors and the gateways in a different network with READ-ONLY Network access. Wish I could provide a time table for Sensor based Admin privileges but at this time we do not have one yet.

Larry_Woods · ‎Dec 12 2022

Ok, i understand. Making your own would not be recommended and I would advise reaching out to your Cisco Account team and/or Cisco Meraki team to talk about this as a Feature Request so we can track the use case and develop this kind of solution.

Larry_Woods · ‎Dec 9 2022

Do you mind elaborating on your use case or problem you are trying to solve for?

Larry_Woods · ‎Aug 25 2022

They can be found just about anywhere. Amazon sells them. If you use or buy through cabling or electrical companies such as Accutech, Graybar, etc, will gladly sell you them. You can also find them at Bestbuy/Walmart/Target stores (tho limited). Just shop around for pricing. I would keep the cabling type consistent if you can to avoid inconsistencies. If you have Cat5E cabling, get the Cat5E patch cable. If you have Cat6 cabling, get the Cat6 patch cable. Stuff like that. If you are unsure what you have, check the back of your wiring closet patch panels and look on the sheath of the cabling as it is terminated and it will tell you the type on there. It isn't the end of the world if they do not match as I have not seen issues while working on the field but I seem to always like to keep thigns consistent.

Larry_Woods · ‎Aug 24 2022

You will want cables WITHOUT BOOTS to be the most effective honestly. Cables with boots has some advantages but ultimately it makes the cable less flexible especially in smaller tight spaces (like you see in the back of a MV21) and has extra plastics/rubbers to help 'protect' the 8 strands in a Cat5/6/7 cable. Here is a picture of what I mean when I say NO BOOTS.

Larry_Woods · ‎Jul 18 2022

Unfortunately the cables are not visually differentiated. Only real option is track carefully as things are replaced.

Larry_Woods · ‎Jul 18 2022

Yea, and understable on the confusion. The first batch was ordered as green as we were trying to get replacements out ASAP and green was the first color we could get out to our customers first. Moving forward, all cables will be white.

Larry_Woods · ‎Jul 6 2022

Basically we are evaluating what makes sense to maintain and update on an ongoing basis. As of right now, we recommend people use the IPVM tool (https://calculator.ipvm.com/) or System. Surveyor (https://systemsurveyor.com/free-trial) as they regular update these tools. Full disclosure there will be limitations to both unless you have accounts so fair warning. Having a 'go to' tool for planning and design is something we know people desire and is top of mind on how we make this happen so please stay tuned.

@KRobert... I have actually been trying to test this scenario for the last 18 months or so and it has been pretty consistant. I have had a MT12 with the cable ran into my shower so that I can show when it detects water but if you notice it does take some time to NO LONGER detect water by the examples below... Theoretically for you, this could work but it will not be immediate as I have seen upwards of 4-5 hours after turning the shower off before the sensor no longer detects. But as @Ryan_Miles is accurate as the MT12 is primarily for the use case to detect water... not the absence of it. I have also tried this in the back of my toilet tank (THE BACK PART) to see if it could be useful to show that after a flush it could show some data around no water being in the back tank but sure enough it just never has enough time to dry and thus always shows as water detected. But the big thing here is that you will never be immediately notified if that tank is empty as it would take time for the sensor to dry.

We now support up to 32 sensors per gateway @DougReimers just so you are aware... https://community.meraki.com/t5/Feature-Announcements/32-MT-Sensors-Per-Gateway/ba-p/130243

Larry_Woods · ‎May 12 2022

Updating post here as we now support up to 32 sensors per MV and MR if you are latest GA versions of code for MV/MR.

I had an issue where in order for me to control the inflation and deflation of all 50+ of my holiday inflatables that it required multiple circuit breakers independent on one another along with smart outlets to be able to inflate and deflate them as needed. Setting a timer for them inflating and deflating (basically turning the power on/off) was easy to do in the smart outlet app from my phone. One issue is only I can do it from that app from my phone and if my significant other or someone else needs to inflate or deflate, they do not have access. This becomes a bigger issue when wind speeds increase to over 15mph and can damage the inflatables thus desiring to deflate them as necessary. To accomplish this now I had 7 different smart outlets to go and manually turn off/on if I had to intervene immediately. The basic purpose of the project was find a way to simultaneously inflate and deflate my inflatable army at the same time that could be done by anyone just by pushing a button. Using the Meraki MT30 connected via Meraki MV to monitor the area, I used a connection with IFTTT to trigger and connect my smart outlets to an action (like a button being pushed) from the MT30. Now i can raise my army whenever I need them do defend me in battle! MS gnome and MV gnome were here — they've been safely returned home!
