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?
What sensors are you using to measure your humidity? Have you got anything you can calibrate against?
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.
