Documentation not great, nor the implimentation.
For Solar Powered WiFi Weather Station V3.3
The published code doesn't work, as Blynk has been broken by Blynk 2.0. I did manage to get updated code from the vendor, but there is much still missing from the documentation - e.g. board type etc. Also, it reports windspeed but there is no indication of units. The documentation isn't clear on this, I'm pretty sure it's not m/s as if so there is currently a hurricane here!
After getting the unit to work, and report to Thingspeak, I discovered it stopped sending temp, humidity, pressure (but was still online, and reporting windpseed, direction, and battery voltage) to thingspeak after 24 hours. There is no way to reboot it without getting a ladder out, so it's really not a practical device to leave on a roof. Rebooting it did in the end bring it back online and start it reporting again.
Given that the reason you're probably looking at a solar/battery weatherstation is to use it in a remote location, this makes it slightly useless (at least to me). I'm going to see if I can get a cable up there and do a PoE RPI weatherstation instead.

Hi There Richard! Thanks for your review. We are replying after 2 Months, as we did test the Project again (as Blynk was not your preference, so you wanted the firmware only in Thing speak) and have recorded the functionalities. The product is working as expected.
The Unique working of the project itself is that it is recording the sensor's value for a minute and then going in sleep mode for 5-10 mins. It is designed to save on-board battery's power because the battery's power is used to not only power the microcontroller but the sensors also (As the nominal Li-Ion battery requires charging time of up to 4 hours from a USB-C Which is a constant supply, think of the fact that how can you actually arrange the sun to give the radiation to the solar panel for constant charging).
So, you actually don't need to reboot the device with any ladder out, until you feel that your network credentials are changed, or you want to change something on board.
We are glad to hear that due to this project, you will be able to build yourself a PoE RPI Weather Station. We are eager to see the results Rich!
