        yeah, have a few installed at home from when I got the property unsure how to configure them, unsure if same brand though

      • bargaino on 28/07/2022 - 21:45

        to be fair, they don't say anywhere exactly what this is!

        It is a battery-powered PIR sensor, ie passive infra-red (with a Zigbee radio). HTH.

    • jong on 29/07/2022 - 01:39

      It's a battery powered Zigbee Passive Infrared motion sensor. If it detects a warm body moving in its field of vision, it can announce that via the Zigbee radio system.

      If you have a home automation system with a Zigbee receiver, you can use these as simple motion detectors for a burglar alarm, or you can use them to turn smart lights etc. on and off as people move through the building.

      They've also got a Lux (light) sensor, so they can feed how bright/dark a room is into your system.

      • Astronaut Joe on 29/07/2022 - 09:34
        +3

        The lux sensor on these is a bit useless. It only reports when the sensor is triggered, so you are effectively getting a reading after the fact. Which means you can't create any automations based on changes in light level.

        Not only that, but even basic routines get needlessly complicated. For example, "don't trigger if the light level is > x" won't work. You need something like "When motion is detected, if the light level is > x then don't do anything".

        It gets worse though. The default reset time for the sensor after detecting movement is two minutes - so after it is triggered, the sensor is effectively offline until it resets. There is a simple hardware hack that reduces the reset time to 5 seconds (https://community.smartthings.com/t/making-xiaomi-motion-sen…) but it is still a pain that it needs to be done.

        In summary, then. These are cheap and cheerful sensors that work well if your requirements are simple, such as "turn lights on for X minutes when motion is detected". Anything more complex can be done but it is more painful than it needs to be.

    I've used these for years and they're great. The only thing I don't like about them is they go to sleep for 1-2 mins after a detection which isn't ideal in some situations. The new Aqara P1 motion sensor is a lot more configurable - you can set the timeout down to 1 second. It uses 2 CR2450 cells to make up for the higher power draw, but if you leave it at the default 30 seconds Aqara says they'll last 5 years.

    They cost $39.99 each when not on sale though. If the sleep timeout isn't an issue, the original model works great!

    • NigelTufnel on 28/07/2022 - 21:05

      I've heard that the P1s are not nearly as reliable though. For most use cases for me (lights) the timeout hasn't been an issue.

      • eug on 28/07/2022 - 21:44

        I've heard that the P1s are not nearly as reliable though

        Both of mine have been working great so far. The last comment in that reddit thread mentions the latest version of z2m fixing a lot of the issues.

        When I first got the FP1 presence sensor I used it for a few weeks with the Aqara E1 hub and the Aqara app connected to HA as a HomeKit device. With the E1 hub there's an option to "Reset unmanned status". Everything worked flawlessly.

        I then moved it to zigbee2mqtt and a Sonoff Zigbee 3.0 Plus. It started getting stuck in "home" frequently. The sensor position never moved. So it could be the software that's the issue rather than the device itself.

      • salem on 29/07/2022 - 09:21

        Yeah I regret getting a pair of P1s instead of more of the originals. Can't adjust the sensitivity from inside HA. The options are there, but you change them and they pop back. They definitely have much shorter range than the originals in default setup. If I can work out how to adjust the sensitivity though, maybe via pairing to my xiaomi mi home hub first, then adjust in mi home, then pair back with my sonoff dongle? Will have to carve some time out to muck around to test.

          The options are there, but you change them and they pop back.

          You have to press the button on the P1 right after you change the setting in HA.

            @eug: Cheers! Someone on the Reddit thread said right before you change the setting though. Easy enough to test, I'll work it out! :)

    • QuQ on 28/07/2022 - 21:21

      if you need something that accurate wouldnt you just go with a Aqara FP1

      • eug on 28/07/2022 - 21:36

        if you need something that accurate wouldnt you just go with a Aqara FP1

        I've got that too. The FP1's response is quite a bit slower than a PIR. The 'enter' event is much quicker than the 'home' event, but it's still slower than a PIR. It's usable in some situations, but I use it in a bathroom and another room where I want the lights to come on the moment I step in, so I use a PIR sensor to turn the lights on and the FP1 to keep them on.

        • Borg on 29/07/2022 - 10:50

          Why not use the PIR to also turn off lights when "No Movement is Detected". That way saves the need for the FP1?

          • eug on 29/07/2022 - 10:55

            @Borg:

            Why not use the PIR to also turn off lights when "No Movement is Detected". That way saves the need for the FP1?

            The problem with PIRs is they're great for detecting motion, but bad at detecting presence. e.g. if you're sitting on a sofa, chair, or toilet and not moving much, a PIR will think there's nobody there and switch the lights off. The FP1 can detect small movements like breathing and keep the lights on.

            The FP1 can also detect through glass unlike a PIR, so it can sense someone behind a shower screen.

                  Wonder if it would detect floating motion to keep the lights on!

    • Astronaut Joe on 29/07/2022 - 09:36

      You can hack the original ones:
      https://community.smartthings.com/t/making-xiaomi-motion-sen…

      • eug on 29/07/2022 - 09:45

        I did the hack when it was paired with my Xiaomi gateway which was connected to HA. Every time it detected motion, the gateway would beep. It looks like the hack puts it in a pairing mode and the gateway just confirms it every time.

        It'll probably work fine with the Sonoff zigbee stick I use now though.

        • Astronaut Joe on 29/07/2022 - 09:51

          That's weird. The hack works fine with my Conbee stick. The poor old Xiaomi gateway is probably getting confused.

          • eug on 29/07/2022 - 10:26

            @Astronaut Joe: Yeah, it must be a gateway thing. Has the hack affected your battery life much?

            • Astronaut Joe on 29/07/2022 - 15:36

              @eug: I'm still on the original battery, so if it has affected it then it has gone from "a long time" to "a slightly less long time".

  • 10101010101 on 28/07/2022 - 20:46

    Good price, tempted but actually don't really need any more PIR sensors. Would recommend generic Tuya ZigBee ones for those starting out as they use AAA batteries and are therefore dirt cheap to run and last forever before needing a battery change. However based on previous experiences with the Xiaomi ZigBee PIRs, those original batteries last up to 2yrs.

            @joohny: The Sonoff Zigbee 3.0 USB Dongle Plus seems to have replaced the Conbee as the default go-to stick as it's really cheap and has a more modern chipset.

          • 10101010101 on 28/07/2022 - 21:59

            @joohny: I use Home Assistant + Sonoff Zigbee USB dongle 3.0 with ZHA. Works well.

            I feel like I'm spending a fortune on CR2450 batteries at the moment for all my other Zigbee devices. I buy cheapo no name ones - not sure if it is cheaper or more expensive in the long run hence why I'd strongly advise to go for AAA powered devices.

              @10101010101: zigbee devices chew through battery like no tomorrow, the worse of all is the smart things motion sensor from Samsung, they used cr2 battery and if mounting them on high traffic area the battery cost will be on pair with the device itself in a year or so. Xiaomi one has quite good battery consumption and some use very cheap 2032 one.

              • 10101010101 on 28/07/2022 - 23:33

                @lgacb08: I've got a bunch of Samsung motion sensors. The CR2 batteries seem ok for me. They seem to last so far. If I had to start again I'd just go for the AAA battery sensors or even mains powered for some. I picked up Samsung Vision sensors cheap during the JB clearance so use those as well.

              I used to buy cheap Ikea CR2032 cells, then I realised they really don't last very long compared to brand-name ones. I switched to brand-name ones and they last much longer.

              I bought two Aqara motion sensors in late 2018 and Jan 2019. I replaced one CR2450 last year and the second one is still going. They must have come with good quality cells.

        • zorrt on 28/07/2022 - 21:58

          may not be comparable to these, at least not what the spec says. The aqara also has a built in light sensor which can be used as a condition for when the light should turn on or off. This only gets a reading when motion is detected however.

          • 10101010101 on 28/07/2022 - 22:00

            @zorrt: Good point - Lux sensor would be awesome and very useful. I just use time based automations for mine. Haven't worked out the sun-angle thing in Home Assistant. Time based is kinda annoying as the daylight patterns change with seasons and I therefore have to update my automations.

            • eug on 28/07/2022 - 22:11

              @10101010101:

              Haven't worked out the sun-angle thing in Home Assistant.

              If you've set your home location in HA's settings, the Sun integration will track sunset and sunrise times automatically. So in your automation you can just specify sunset and sunrise rather than specific times.

              • 10101010101 on 28/07/2022 - 23:35

                @eug: From memory when I tried to set it up I couldn't properly do the time offset and my automation wasn't triggering. Will need to take another look. Basically I need my lights to come on an hour earlier than Sunset and stay on probably two hours after sunrise as part of a motion trigger automation.

                  @10101010101: @julz there's some nuances with Sun that took me some time to understand. "after sunset" is the period from sunset to midnight. And "before sunrise" is midnight to sunrise. And if you want something to trigger at night, you'll need to remember a little high school logic classes. You'll need two conditions separated by an OR not an AND. eg After sunset OR before sunrise. Don't try and use both of the "before" and "after" buttons inside the one sun condition. Then just add your offsets from there.

              @10101010101: If you're using HA then I would recommend getting the aqara light sensor which I find works really well. I've moved away from time based and sunset sometimes ends up being too dark or too light even if I offset the time especially when there's thick cloud coverage eg storms. Light sensors for me I found more consistent.

    • Astronaut Joe on 29/07/2022 - 10:00

      The thing about these is that they are tiny - less than the size of two AAA batteries.

      • eug on 29/07/2022 - 10:25

        Yeah, the size was what drew me to them. They're so tiny and unobstrusive yet have really quick response times. In my bathroom I had one of these battery-powered Xiaomis and a DIY module consisting of a Wemos D1 Mini running Tasmota with the official Wemos PIR shield. The Xiaomi detects motion before the Wemos does.

        I'm normally a big fan of NiMH cells but the battery literally lasts years for me so I have no qualms using them.
