Oh I remember my next door neighbour, I fitted a small carriage type outside lamp around 40 watt, it had a light sensor so as it got dark it came on and lit a small area around our back door so we could see to enter house.
Neighbour however fitted an illegal 300 watt quartz lamp at their back door, really over kill. Our light was not motion sensed, so at dusk would light if we had it switched on, theirs was inferred sensed, all was OK until a cat set off neighbours lamp, which was so bright it caused my light to switch off, once the timed was out on neighbours lamp it would switch off, and mine would switch back on again, my light would then trigger neighbours lamp, which would come on again, so mine switched off, until neighbours switched off.
My son could not sleep due to continuing flashing lights, I did complain to neighbour who said it was necessary so any intruders did not injure themselves, so considerate, my visitors used front door, I could have complained to council as over the 150 watt limit, but just turned my light off.
OK that does not help you, but you have to laugh, however I have some so called "Smart" bulbs, some seem to remember how set, others default on, and some default off. So if I turn off my spot lights in my bedroom, once the lights have been switched off, next time used the spots default on again. But the strip of colour changing lights in living room, retain the last command.
The problem is there is nothing in the instructions to say what they will do, it is suck it and see. And bulbs no longer give out inferred in the same way, I have seen when visiting a collage walking down a corridor the lights came on in sequence as I walked, so clearly they were set not to set each other off. Also been in buildings where they had motion sensors to reduce energy bills, when a room full of people are all working on computers surprising how little they move, at least we all waved to each other, or at least at the sensors.
Wonder if it really saved money with all the disruption to work? In Chester in around the 80's a new building was built getting all awards for energy saving, only heating was the lights, which were fluorescent, built by Manweb which was the local electricity board, (Merseyside and north Wales electricity board) to demonstrate how energy could be saved, it was so good, it has now been demolished. Same with the Police building also state of the art, now demolished. OK with Police building built before computers and had a very clever filling system spanning all floors, which computers rendered redundant.
