This time of year the sun tends to cause interference with my garage door blockage sensors.

I've been manually closing my garage as a result, but finally took the time to "fix" it

PVC threaded female end to slip on. Didn't glue it, but it's jammed on tight enough. Sensor still works fine when an actual object is in the path.

I think I may need to do something similar.

At this time of year, sun coming through the skylight hits the temperature sensor in the dining room for an hour or so each day.

    Put a white painted shroud on it designed for weather stations, air will flow through and it'll be unaffected by the sun. I just built one for myself this week, now I can finally measure air temp outdoors (not the surface temp of what it's affixed to)

    Wow, that's really cookin when the sun is on it. Is that linked to an HVAC system?

    Indirectly.

    Home Assistant is taking a weighted average of 4 sensors (this one at only 20% of the total) and using that to play tricks on the heat pump. So it caused only around a 1.2°C difference in the value that matters.

    Of course it's a nice spring day today and I have all the doors and windows open, so that heat pump is on fan-only mode anyway.
