Looking for ideas on how I may use RSSI to detect motion. Anyone trying something like this already using esp devices?
Could I just use 24hr average and watch for value to drop by xx and presume that’s motion?
Hm…i’d say that looking on a signal history of one of my esp’s…not really… module hasn’t been moving, neither router, but signal fluctuates quite a lot. Wifi signal strongly depends on multiple situations, so i don’t thiink it would be a reliable source of movement.
It might be a test to see if you are a robot. All that metal would affect the signal more.
This was my thoughts, “how much would a bag of water really effect RSSI”, but I know there are several projects using RSSI between device in room and AP to determine motion in room. Xfinity is actually upselling this feature, which is concerning, so there must be at least some there there.
Also take a look at cognitive systems implementation. I think this may be what xfinity uses.
This project claims to have it working on esp32
While it’s probably possible to detect motion that way, the fact is that people have often troubles even with motion sensors.
What type of motion?
Many sensors can be used for something else they were originally designed for.
For example ultrasonic distance sensor could be used to measure temperature.
Sensirion uses acoustic sensor to measure CO2.
General
I do not need to track a person and I already have motion sensors. Just looking at another data point that may be useful with low resource use/maintenance
Actually one if the uses was detection of cars passing (under 3mph)
Ahh, a data collector. I understand the temptation “because it is there” to collect. Just remember it can lead to hoarding very quickly. I collect a lot of data. Most of it is incredibly boring and mostly useless so I never look at it. But every once in a while I am able to answer a question, since I have the data that answers it.
The latest one was when and why did my HPWH stop working properly. Since I have two water heaters (with the HPWH one being primary) I didn’t notice it from not having hot water. I did see the increased power usage and the change in temperatures and the status of the EEV (that pointed to the problem of the refrigerant having leaked out).
I do track RSSI but its pretty boring.
