How to monitor the presence of electricity in the outlet?

Question

Electronics

In Thailand, in terms of reliability - complete Buddhism. The wires hang between the poles like overcooked pasta, the floods are more regular than the measures against them. Electricity disappears and reappears like a perfect random number generator.
Before moving to a new house, comparing several options, I want to imagine how often the light is turned off in each, and for how much. Ideally, plug a certain thing into their outlet, such as a mosquito fumigator, pick it up in a couple of days, connect it to a computer and get graphs when there was electricity, when it disappeared, and when the voltage dropped to 100 volts.
And ideally, you would also monitor WIFI - ping the same Google with Yandex. And also record the noises in the room, like in museums. And also build a graph of illumination and temperature. And also…
Are there any similar gadgets, or something with remotely similar functionality?

Answer 1

There are multimeters with the function of recording readings for a long time. Work from batteries. Search keywords data logger. Some UPS models also have a mains voltage logging function. Power up some laptop from UPS (so that it lasts for a long time) - and then view the graph of the presence and magnitude of the voltage in the network.

Answer 2

What you are looking for is called a registering voltmeter. Here is an example . The truth here is more like a balalaika than a bitten apple.

Answer 3

1) szf.megafon.ru/corporate/equipment/sms-rozetka/ or find similar devices
2) you can have a computer (or something like an arduino) with UPS that pings, for example, a router without UPS

Answer 4

Arduino. Hang the desired sensors + WiFi module + SD-Card for recording. 9B crowns will last for a couple of weeks.
