I'm only at 42N, but find that here (Massachusetts) there is plenty of
sun in winter.   You do need a clear souhern horizon.

The advice that you may need a bigger panel is wise.  If you have a
battery that will run the station for a week, and a panel that will
recharge the battery in one sunny day, you will probably be ok.

I don't know yet how my setup will work during winter. I live on latitude 
of 51 N .

I have a similar setup.  Multiple esp8266’s. Posting data to mqtt broker hosted 
on the rpi.  From there you need the mqtt driver to get the data into weewx.  I 
can troubleshoot the mqtt data with MQTTool.  There are others.

I dont think its enough if you are in a area with "Winter", you have very short 
and flat sun and sometimes weeks with cloudy sky and nebula. I think you need a 
big panel and strong akkus.

Yes, I'm afraid of this too. But I will install the station in such manner 
that I could remove the snow easily from the solar panel. Now I'm testing 
it at home, in the room, trying to "deep sleep" ESP8266 for 1 minutre, then 
wake, send the data and sleep again.

Its USB powered because in Winter there is snow on the panel in my area and so 
solar dosent work.

I use ESPEasy instead of Tasmota but basically it is the same. Is your 
station powered by USB or solar panel?

I use a ESP8266 with "tasmota" for my homemade Weatherstation. Its easy to 
configure, didnt need much power, sends mqtt. Tasmota knows the most Sensors by 
default and send all mqtt via wifi to weewx-mqttSubscribe driver.

Thanks , now that you showed me it's possible to get data into weewx I feel
a zeropi weather station is the way to go. The zeropi would have to be
located outside on the mast  with  the sensors and powered with a solar
battery.  It might be a challenge getting an indoor temp sensor connected.
