Well over a year for me. Swapping the batteries just takes a few seconds in the outdoor module and rain gauge. The anemometer might be more problematic if mounted high up to catch the wind. Note the rain gauge and anemometer are separate add-ones and not included in this pack.
Yes, 2x AAA, and mine lasted at least a year. My outdoor module died after like 5 years and I’m buying again (y) 🏻
Like once per year
I just went to purchase and had the same. Can someone that has one answer how long the batteries last in the outdoor module please? They look to be AAA and I would use rechargeable but I don't want to have to do it every week (or even every month).
Wanted one of these for a while but I always end up reading the reviews which puts me off every time. Seems the outdoor module needs charging regularly which is a turnoff for me.
