My 84 year old mother woke up during the night a couple of nights ago, didn't put the light on and got confused and went to the loo in the next door room. She isn't confused during the day but after a fall a few months ago has been sleeping downstairs in her dining room with a commode in her room. I think if she had a light sensor which came on when she got out of bed she would have seen the commode and remembered to use it. I just wondered if anyone had successfully used an indoor light motion sensor? Thanks.
