Enocean: Energy Harvesting Switches and Sensors



Switches or sensors without wires? No problem if you use batteries. But without batteries? The Enocean alliance created a standard for such devices. So let’s have a closer look at switches and sensors that do not need a battery change. And here I have a cheaper Chinese “clone.” How does it compare? And how do these devices compare with Zigbee or BLE switches and sensors? A lot of questions!

    Very interesting. As you say, not suitable for lots of scenarios, but I'm sure this technology will be the perfect solution to a problem I will have one day, now that I know it exists! Thanks

    Is there a risk of 2 neighbors having similar devices and affecting eachother?

    Love this stuff. It would be so nice to get away from having to power automation gear. Hoping this technology gets really really cheap 🙂

    About 12:50 Luckily a new standard is in the making to make sure that burglars have to handle this use case to be compliant: ISO-112 (ISO-911 in the US, ISO-999 in the UK)

    2:55 "the flat battery always happens on a trip with friends"

    Well, not really, but I get your Murphy reference.
    then again, when you go on a trip with friends you have friends who can drive to the next service station and get a new battery which will last you at least a year again. That is; if you don't preventatively replace the battery anyway, which I would do if I was to go on a trip into noman's land.

    Andreas I envy you for the fact that you do not mind learning about many new things. I find it difficult to adopt new technologies that do not serve an immediate use for my surroundings. I try to get many tools under my belt but it feels like my tool belt is tiny.

    A very informative video. Although I like the idea of switches without battery ( I am using a couple of Philips Hue taps, which work with zigbee2mqtt now), I think the prices are a little high and adding yet another usb stick to my fhem setup (3 so far, all on a short extension cables to get some distance to the NUC) will make it look more and more like a kraken.

    Hi Andreas, I'd also put Z-Wave in the competitors chart. Actually, it is even closer to EnOcean than ZigBee, as it uses the same frequency.

    Very interesting. Didn't know how much a raspberry can distort a signal up close.
    Explains why i had issues on a simple project i tried years ago. That was an 8266 btw.

    He always says "here is the guy with the Swiss accent" but I never hear any trace of accent

    Andreas, thanks for the video. While I don’t fully understand, you have me thinking… again. I'm monitoring my water meter remotely and using batteries since I have no mains power at the street with the meter. The sensor is a magnetometer that is mostly asleep waiting for the magnet in the meter to spin (polling). With your help I now see that spinning magnet as 1. a voltage spike interrupt trigger, and 2. a parasitic (magneto) energy source. This solves a bunch of problems for me and creates a whole set of new ones. What The Flux, I can't loose, right? I thank you… I think. 🙂

    BTW, the burglar example made perfect sense to me.

    conclusion: we need to teach burglars to break into our homes in a sensor-compatible way. Can't be that hard … nice sensor topic.
