I looked around and anything that gave me a lot of historical data would be prohibitively expensive........monthly or yearly fees and so on.
So we went to Lowe's and bought a Acu-rite weather station.
I has one sensor that will be in the coop...have to put lithium batteries for the cold.
The monitor goes on the desk in my office, it gives temp and humidity, I haven't read the complete instructions yet.
The unit was $35 then a few bucks more for lithium batteries.
I says it has a 330 foot wifi range, the coop is about 100 feet from the house.
I am going to install it tomorrow and will give a follow up.
I think it should work out.
As a Maintenance Technician I like to see data , lots of data....or it might be my OCD kicking in !!
