Do you need a thermometer with a broadcast of indicators somewhere on the Internet, are there any?

Question

Do it yourself

I want to collect the temperature of the heating radiator at home and put the readings on the Internet. I found a usb-thermometer for a PC, but I consider it superfluous to keep the machine turned on around the clock for this. Is there a less energy-consuming thermometer for such a task?
From the interfaces in the apartment there are ethernet, WiFi, a TP-Link WDR3600 router with a usb port, a usb port on a PC with a constant power supply for charging.
Clarification: there is no soldering iron, it is scary to change the router, so a device in the “connected-configured-works” format is highly desirable.

Answer 1

You can steal devices from narodmon.ru/ , the "catalog" button

Answer 2

That's right, don't forget to read about the project as well.
And for connecting routers with OpenWRT narodmon.ru/#openwrt
Without flashing into OpenWRT, alas, it is difficult to force the router to transmit something to the Internet. Yes, and "be afraid of wolves ..."
Alternatively, choose a monitoring device with eth, which through your router will itself transmit sensor readings to narodmon.ru

Answer 3

In fairness, I want to add that, as an option, you can buy a used router without USB, but with UART and flashed in OpenWRT, such as dir300 (rev. A / B). They now cost a penny and it’s very difficult to come up with something cheaper. Well, upload the data to narodmon.ru.

Answer 4

I developed a device for collecting temperature from a large number (tested on 2 lines of 100 m with 28 sensors each) 1-Wire (DS18B20) sensors and sending data to the server via GPRS. There is a backup power supply.
If interested - in a personal or skype.

Answer 5

I took a few pieces http://elephant.embedders.org/SMALLMETEONEW/smallmeteonew.html - they are easy to set up, they work stably.
