My seismometer detected it, i.e. a three shade ceiling light fitting with the shades at slightly different heights so they are not touching but can touch if they swing.
We have several sets of indoor windchimes that serve the same purpose. They detected this mornings 5.3 but since we were upstairs we felt nothing. The lower floor of our house is below ground effectively set into the bedrock. We have two desks that I always align with each other after each tremor, this morning I found them 5cm apart. Yesterday we were downstairs and had to hold on to the 4 computer monitors standing on the desks
