WOW. Amazing weather buoy! Love it…
Hi @dima.avramenko,
Are you still following this discussion regarding your situation?
What distance line of sight is your intended Sky from a location where you might be able to install a hub connected to wifi?
The distance between Sky and Hub can be several miles but the distance between your hub and wifi will be much less, wifi distances.
cheers Ian 
Hi @dima.avramenko,
Regarding remote power supplies.
There have been several comments on different topics here and from my own experience trying to use a USB power bank as an Uninterruptible Power Supply doesnt always work (unless you find one that does).
Here is a comment, but you can search for more.
cheers Ian 
Hi @iladyman,
My use case is self contained 3G Sky reporting from a remote location (beach). This would be for a beach that normally takes 1.5 hours to get too. it sucks to arrive to the beach for kitesurfing only to find out the wind reported by some other stations at locations away from the beach do not apply here.
So I was thinking to hide Sky on some tree or install a poll at the beach and then have it send data via 3G or 4G. So everything needed, needs to be part of the installation.
The sky can work on its own up to a year. The hub, can probably be to powered by battery. same for WiFi device. I would be happy if that installation could last a ONE month and I would replace a battery once a month to keep it going.

I need something permanent to install and leave on the beach, which has no weather station. Everything needs to be self-contained and last at least a month. I could deal with replacing a battery once every 30 days, but of course if could last 6 months would be so much better.
I guess problem is WiFi is very power hungry… so not sure any power bank could power for so long.
What is ArchiveSW ? I could not google it.
This is awesome… But only lasts 2 days… I guess, since it’s wifi and requires powering phone and base station, maybe Sky is not the best choice for remote weather station…
you will find it just here
Hi @dima.avramenko,
A Sky with the solar power accessory mounted in the wind should not require anything once it is installed it is fully self powered and should be maintenance free for several years perhaps 5 to 10 years! It would not like leaves between the sensors. And sometimes drops of rain between the sensors creates false wind readings, but that problem is being improved.
Position the hub somewhere in line of sight which can be a long way away.
Choose from the above suggestions for your wifi to mobile network.
I like the idea of the raspberry pi with a usb broadband dongle so everything is 5V usb and if it reboots every night then it might also avoid the issue of mobile companies limiting the time of your connection.
(A mobile phone as a wifi hot spot does work fine too. I just dont know how reliable it would be. I have used my mobile phone hotspot for all my distance and remote speed tests but only for periods less than 3 hours.)
For your 5V usb power supply you could use a variety of solar panel battery systems with a usb output ideally of 2Amp capacity but it doesnt use that much all the time. But a raspberry pi needs a solid 5V with 2A when it boots up.
Personally I would just buy a 12V motorcycle battery and 12V solar panel with its own regulator and a USB adapter for 12V, like in a car because they are all easily available and I would design it with plenty of capacity for bad weather so it doesnt have low voltages. But there are better more efficient battery systems, which people on this forum will help you with…
If you use the standard weatherflow web pages then there is less software to set up. When you buy and setup the weatherflow smartweather station it provides your web service with all your readings live on the web.
Thanks for the interesting topic which we all will be interested with your results.
cheers Ian
Hi @dima.avramenko,
As I am looking at similar options to create a simple reliable power supply for my entire base station (hub, raspberry pi, router, solar panel and battery) here is a link that I might purchase from my local supplier in Australia that could control the solar panel, battery charging and provide the usb power supplies:
(It would be available from other suppliers nearer to where ever you are)

WF team- I see an opportunity here! Maybe the WF team could design/manufacture a solar power, waterproof 3G HUB? Or, a solar powered 3G SKY (with temperature, humidity, barometer and lightning sense)? Or, design/manufacture a module which can easily slide into the now empty SKY battery compartment? Note, the module would be powered via the (new) SKY solar accessory, and have its own Li-ion batteries, 3G modem, temperature, etc. sensors.

A commercial grade station purpose designed for autonomous remote operation has long been on our road map. The spec, build, power supply, and communications suite would be a scaleable design based on our 22yr background operating remote weather networks and leverage some of the new technology you see in our current home weather stations.
We have yet to focus on the commercial station. So for now, you guys and gals will just need to get creative with the home weather station.

I totally agree with you.
And we get a profit due in large part to Weatherflow’s extensive experience in station design and installation.
As well as I suppose you learn a lot due to the high amount and world wide spreading of the SWSs.
Thanks again for making the step from a professional weather station to a home one.
Would you do it again if you have known before what you know today related to offer a home version?
The quality of data (we are looking forward to the solution of the rain issues 
) produced by the SWSs out in the world os amazing as well as the support you are providing.
And together with the creativity and the competence of the active forum user it is highly presumabl to solve nearly every question or bring any idea one can have to life.
I’m glad to be part of it.
Go ahead all together.

LoRa might be something to look into. You could use an ESP32 as a WiFi gateway, then pass the data through a LoRa node. ESP32s and LoRa nodes are both pretty low power devices and from what I have read about LoRa, it should have a range of about 10kM even in less than ideal conditions.

So is there is a phone in there?
