Maybe if you'd read the replies to your question you wouldn't be creeped out. There are a lot of good use cases and I haven't even though how it could be misused before you brought it up.

You're the only creepy one here bro. If you can't even imagine practical uses for this you definitely need therapy.

Don’t open the blinds as long as there is someone in bed?

You're right in that it's a useful tool for various kinds of abuse, but so is almost every useful home automation/home security sensor.

The most obvious/useful use cases I can see are:

• turn on bedroom lights when the last person gets out of the bed
• turn off whole house lights when the last person gets into bed.

Both should be easy with load cells under the bed legs but rather difficult otherwise.

(Useful assuming a household of two adults in one bed that is).

Honest question, do you use Home Assistant?

Yeah it's creepy, but I think the more logical reason for wanting it is to know whether or not their spouse is being faithful. My previous comment was sarcastic because I thought you were being sarcastic yourself.
