We built a house 7 years ago and it’s insulated and has double glazing. I’ve installed Home Assistant with temp sensors in the bed rooms and seeing 70%+ humidity levels. Temperature is always above 16c
We ventilate it, but still it’s 70% in the bedrooms. WHO recommends 40-60%, so we’re a bit worried.
Living room is around 55% during the day when we have the heat pump set at 21c.
As it’s pretty humid outside I think it’s almost impossible to get it lower, but are there any other tips? I don’t want to run dehumidifiers. Would an HRV like system help?
I’ve got Sonoff SNZB-02 temp sensors. I also have a weather station; there is a difference of up to 5%, so I am taking the readings with a grain of salt.
I just bought a dehumidifier which has a RH sensor as well, which is almost the same as the reading of my Sonoff sensors.
