A simple but effective monitor system that's well suited to basic as well as complex environments.
This is a basic but flexible device that provides text message and email alerts for power up/down events without a yearly subscription cost such as with Ting. I have a fairly complex power environment in my house, where most of the electrical circuits are protected by a 20KVA Cummins Onan standby generator, and I have several UPS devices that protect critical appliances during the 10-second delays between utility failures and generator reinstatements. I'm currently using three MySpool devices to monitor this environment, but I'll probably add more in the future. One MySpool device is connected to an unprotected outlet, and it lets me know when a utility failure occurs and how long it lasts before the utility company fixes it. A second device is connected to a generator-protected outlet, it also tells me when utility power fails, but then it also confirms that the standby generator has kicked in and reinstated power afterwards. A third device is connected to a 1500VA UPS that is plugged into a generator-protected outlet, and which I use to ensure constant uninterrupted power to the main kitchen refrigerator. The UPS helps guard the sensitive electronics you find on most modern refrigerators from power outages and surges, and I think it has allowed the last two refrigerators I've owned from having any significant issues in this regard. (The previous refrigerator simply wore out physically, but it continued working electrically until it was replaced.) However, UPSes themselves will eventually die when their batteries expire, and the MySpool device I connected to it should let me catch this situation quickly and let me replug the refrigerator to a backup UPS or directly to an outlet until the UPS is serviced and before food starts to spoil. I could of course do the same thing with three Ting devices, but each Ting device would need a $49/year subscription while your property insurance will likely pay for only one. Ting will give you predictive alarms for potential wiring problems in your house, but in at least one of my cases the things that Ting can see will likely be shielded by the refrigerator UPS. I might eventually install a Ting device in my house, but I see the MySpool devices performing a separate monitoring function that Ting isn't really suited for. I liked how easy it was to set up each MySpool device. You simply plug the device in to an outlet and then connect your smart phone to the SAS-xxxxxxx WiFi SSID that appears in Wi-Fi Settings. You will be automatically directed to a home page on the MySpool device where you select a local home WiFi SSID in your house that provides Internet access and then enter the password. Once this is done and the settings saved, the SSID for the MySpool device disappears and the MySpool device registers as an unclaimed device with the MySpool infrastructure in the cloud. You should write down the SAS-xxxxxxx ID from the first device that you set up, because you'll have to manually enter it into the MySpool account that you create in the cloud so that it knows which unclaimed MySpool device that it's heard from needs to be associated with your account. Once it attaches the MySpool device to your account, you can set it up to send emails to up to two email addresses, and text messages to up to two mobile phones when the device senses a loss of power and when power is reinstated. You can customize the messages as necessary so the events make sense to you. Once the first MySpool device is manually entered in this way, every future MySpool device that you power up and configure with the same WiFi SSID and password is automatically associated with the same MySpool account in the cloud, so you then just have to configure target email addresses and mobile phone numbers for them and the specific messages that will be sent. You'll get a preliminary email on each of the email addresses that you configure, from which you have to click on a link to "subscribe" to future power up/down event messages from each of the MySpool devices. You test each device just by unplugging it and plugging it back in again, and checking to make sure that you received the appropriate emails and text messages. I've only had my MySpool devices installed for about a week, but so far I really like them. The only thing I don't like is that text messages are rate-limited to allow only one message from each device every 5 minutes. This is fine for most of my devices, but for the device that's directly plugged into the generator-protected outlet I'll get a utility-failure message immediately, but I won't get confirmation that the generator has kicked in until 5 minutes later, even though the generator will typically restore power in about 10 seconds. When I'm away from my house that could be a harrowing 5 minutes to wait before I know that the generator has started. However, my Cummins-Onan generator has been extremely reliable since it was first installed 15 years ago, so I'm always pretty sure that there won't be any problems. Also I don't think the 5-minute rate-limit is always accurate, one time I only had to wait about 2 minutes for the second message to appear. In summary, I highly recommend this device.

Superb product, excellent support, innovating company.
[UPDATED] I purchased this product to monitor power failures. Here is my independent review. Product configuration was straightforward **if you follow the instructions carefully**. Basic understanding of WiFi enabling/selecting/activating is required. The main idea of the product to use internal batteries to be able to send an email alarm was brilliant! Very innovative. The ability to send native SMS messages instead of relying on service provider gateways was good. As an example, if your provider is AT&T you do not have access to such gateways. Expanding this SMS capability with the Professional Alert package is very nice. The integration of the product with AWS is excellent. I especially liked the ability to manage the device via simple WEB application without overheads of “yet another mobile app”. I loved it’s simplicity combined with flexibility. In addition to the perfect operation, my experience with their support staff was extraordinary. They responded to my emails within hours during the weekend, and I had several exchanges with them thereafter. In fact, at a critical point of my work, their software engineer, Edward, called me live to my cell-phone and helped. MySpool should be very proud of such engineers working for them. Overall, I recommend not only this product but also other ones from this company. This little company in NJ reflects ingenuity, “whole product, end-to-end” superiority, and superb service.

Works as described. Fairly easy to install and activate. When I had problems, I was contacted soon after I requested help from them.

Perfect for Refrigerator/Freezer outlets! Easy setup and works great!
Bought two of these to use on the Refrigerator & Freezer outlets due to breakers being tripped on those circuits and leaving the power off undetected. Now that these are installed (super-easy to set up), I get nearly instant notification (by email and text) that the power has gone off on those circuits, allowing me to reset the breaker quickly. PLUS, I also get notification when the power has been restored to those circuits. All of these notifications/alerts can be easily customized and configured in your online account (also very easy to set up). What's really ideal for me is having two of these installed on different circuits. If I only get notification of one being out, I'll know that the breaker was likely tripped and power is not out to the whole house (making troubleshooting a breeze). These units are going to provide me so much peace of mind when going out of town - no more worrying about undetected power outages that might impact the food in the fridge/freezer. One very important thing you need to know is that these units require constant connection to Wi-Fi in order to notify you of power outages. So, if you don't have your modem and/or router plugged into a battery backup (UPS), these units can't notify you of power failure if power to the entire house goes out. However, you don't need to have a crazy-expensive UPS for your modem and/or router because these detectors need less than a minute of Wi-Fi after the power is out to send the notification. Just get a small $40-50 UPS and then plug ONLY your modem and/or router into this UPS. This will give you 5-10 minutes of internet and Wi-Fi after power failure - plenty of time. If the power is off longer than your UPS unit can supply power to the router and/or modem, it doesn't matter. The detector will automatically reconnect to Wi-Fi after power has been restored and then the detector will notify you the power has been restored. If you want to know of power failures to ANY circuit in your house, these are a very affordable and reliable option (with NO subscription fees - just one-time purchase cost).

Great Product
I Installed this on my freezer plug in the garage and it workes great. If the braker trips on I receive notifications .

No subscription needed.
This does exactly what it says it will do. I needed it to let me know when the power goes out so I can know that my generator is going to go on. Setup was easy and it works flawlessly. Only slight complaint is that the batteries needed replacing and it was hard to get the back off and impossible to put the back completly back on, so it's slightly open. Best part is that you only have to pay for the device not the service.

It works fine, but configuration wasn't easy
I bought this monitor to determine the duty cycle of a water pump that is controlled by a pressure switch from the pressure tank it feeds to. That is, instead of using it to know when the power is out, I wanted to know when the pump was ON and OFF, to see how much time in total it was ON during the day. Instructions are simple and straightforward, but the implementation of the configuration screen is rather poor. I tried to set it up from my phone, but the wifi connection continually droped. I then tried from my laptop and finally could access the configuration screen, but it was really bad and not responding properly. I had to use the "No Scan" option to configure the wifi. There was no feedback from this step, but when I created my online account at myspool dot com, my device appeared there, so all was good. In order to get email notifications, you need to authorize a request you receive from AWS Notifications or something like that, or else, you will NOT get any email notification on Power ON and OFF. After all this was set and done, my device has been working with no problems, and now I have some nice charts in Excel that show the duty cycle of the pump.

Works but you need to connect using Wifi "No Scan" mode
I tried everything at first and gave up as it would not connect to my wifi even though I followed every step (I'm technically sound). Just before I decided to return, I tried the "Wifi (No Scan)" connection option where you have to manually enter the SSID of your Wifi network. Surprisingly that worked immediately even though the normal method where it scans and detects the Wifi was picking the same connection. Any way, it connected immediately, works amazingly and sends alerts when the device loses AC power or when it turns back on. Beautiful. Now I can monitor my Aquarium when not nearby. SMS does not work for outside of US however email works just fine.

Works as expected
Product arrived along with clear instructions. I would advise you make a note of the device ID, since if it does not automatically register under your account, you need to reset it and go through the process again to attempt manually adding to your account using that device ID. The initial setup was straight forward and easy. It connected to my wifi and I could see it on my network. But as I mentioned, the device would not register under my account at MySpool. I tried the manual registration and it did not work either. But an email to the support group did the trick and they added it to my account. Since then it has worked great and I get almost instantaneous notification upon power loss to the device. Worth it for the peace of mind knowing the fridge is monitored.
