Yep, I'll have to experiment a bit. Might need to get a moisture meter to adjust the ventilation.Oldboy said:
It might be enough, but it's impossible to judge. Typically one of those things you'll solve through "trial & error".
Even the opening of the door will sort itself out over time. Maybe place a footstone to set your foot on a little bit up on the hinge side, for a somewhat less awkward opening position?
Does anyone have tips on temperature and humidity meters that also log values over time that I can use in the earth cellar?
I'm looking at something like this https://www.clasohlson.com/se/Netatmo-smart-vaderstation-WiFi/p/36-5561. I don't know if it can handle the environment inside the earth cellar or if the WiFi works well through the walls. Has anyone tried it?

I have one of these: https://www.lfs-web.se/produkt/tfa-klimatlogger-hygrometer/
They work outdoors and in house foundations.
WiFi signals don't like trying to go through stone, soil, and/or metal... The one I have should handle up to 100 m line of sight, I believe.
Otherwise, there's the type that logs as long as the battery works and can be retrieved and connected to the computer via USB. https://www.lfs-web.se/produkt/tfa-log32-th/

Seems perfect with the first link. Then I can also place units outdoors and in the garage + storage. The question is whether it works through the walls of the root cellar. I guess testing is the only way to know. I bought a simple wireless thermometer earlier, but it didn't work so well in the root cellar. It seemed like the battery drained faster because it was hard to transfer values.
Do you have any experience with how long the batteries last?
I have had mine for 1-1.5 years now and all still seem to function. However, only one unit is positioned outside. The others are indoors.
One of the units is located in a room approximately 15 m away from the main unit, and occasionally some values are missed. My guess is that the signal needs to pass through some walls that dampen it. The signal path is not at 90 degrees through the walls but at a very sharp angle, i.e., almost parallel, and it might be that the wall is made of mudstone. (The wall has treetex and gypsum as surface materials, but it's an old Skånelänga where at least the walls around the old kitchen are made of stone.) I have two other sensors about 8 m away where the signal passes through 1-3 stone walls, mostly straight through, and there are no reception issues there.
Try placing the unit by the cellar so that the signal from the unit to the main unit indoors goes through the threshold (wood?), i.e., not through thick layers of earth and stone, and not through the metal on the door either. The signal path is perfectly straight, just like a beam of light.
The batteries are easy to replace, though. It's two regular AAA or AA batteries in each unit.
