Thank you for the quick reply - regarding the security point, I think there was another structural vulnerability that weakened the whole protocol pretty much but would need to look up a reference.
Regarding openness - Could you please point me to any resources?
In general, I would still prefer a WiFi enabled solution (as I’ve got Ubiquiti-based robust wifi throughout my house) to get rid of the need for dongles/extra devices but have not seen anything anywhere as comprehensive as the Zwave ecosystem for WiFi etc.
As far as I know all similar technologies are closed as Z-wave or even more. This concerns Enocean for example. KNX rf might be good, but it’s not competetive in price term. MQTT over WiFi becomes quite supported by Chinese vendors, but it’s not meshed and it’s not working at device profile level.
Just had a quick look on KNX RF, is there any real added value for the price premium? Seems pretty steep for what the feature set is (I may be ignorant though and not see the benefits).
Regarding MQTT over WiFi - that looks very promising to me! I do not really care about device profiles, happy to write simple custom integrations for each of the devices. Could you point me please to some examples of such devices?
The technolog(y,ies) you choose will vary by the country you’re in. In North America quite a few folks will happily recommend you stick with Insteon with the 2413U PLM and NOT the crappy hub. Outside of the US it seems Zwave has more of a stronghold. I’ve heard too many complaints to consider it seriously.
In addition though, since you’re using OpenHAB don’t limit yourself to one technology or protocol! I love MQTT stuff too. Great for DIY sensors and relays but not as pretty as finished products like in wall switches and outlets. The obvious benefit to Zwave/Zigbee/Insteon/etc is the fact they’re not WiFi so not open to the same potential exploits. Putting together a WiFi temperature sensor for under $10 USD that could be run on battery for extended periods is fun and flexible compared to $30+ USD for a prefabricated option.
It’s not really true. You compare proprietary technology(Insteon) with standard (Z-wave). In EU actually there are many similar proprietary technologies, but each country usually has one-two big vendors. For example in Germany very popular brand is Homematic(wired and RF). It’s devices are cheaper than Z-wave and good. So it’s like “Insteon” in US. Somfy is another big brand, but in France with less presence in other countries.
So one can always select one of these - openHAB should support them as well, but we all talk about Z-wave, because it’s not binding us to specific vendor as existence of Insteon might be not questionized, but Homematic or Somfy can dissapear one day, and then you have trouble.
I appreciate the links, I’ve seen them before but I would really prefer to find something off the shelf. I really don’t want to solder or program a chip. I just want to bind something to my network and switch point and send it commands. I know there are more adventurous folks out there, but for me I’d like the “dirty” work to be done and all I’d need need to worry about is sending it commands from OH.
Do you know if it’s possible to use ITEAD (Sonoff) WiFi switches with regular switch (like Aeon Z-wave micro switch for example)? Those switches are really cheap, but it’s not an option - at least for me - if I can’t switch same load with either WiFi or regular switch. Is there a workaround to accomplish this?
The point is, I don’t want to constrain myself on using switch over WiFi only. Since it would be a light switch, I want to be able to turn the light on/off using regular wall switch too (the same thing you can do with Aeon Micro Switch/Dimmer), because I don’t want to sit in the dark if my OpenHAB server dies Aeon Switch/Dimmer has dedicated wall switch connectors, so, it’s easy to connect it to a wall switch. Sonoff does not, and I was wondering if there is a way to connect it (via relay or something similar), so, both wall and WiFi switch could work independently (you can switch a light on using a wall switch, then turn it off using WiFi, or any other combination).
I have chosen to use as few WiFi devices as possible (unless I make them myself i.e. Arduino and even trying to avoid those) for many reasons.
Stop the clutter of my network
Many of these devices are ‘slow’ and adding more will just slow the network even more (devices have to wait their turn and if one or lots are ‘slow’ (i.e. 16mhz Arduinos)
WiFi can be MUCH less secure than ZWave and ZWave doesn’t interface on the same network as my financial files…
Have you seen the recent issues with IOT devices and security/viruses? Why would I want to include that on the same network that my data is on?
True, many of us have the time, money, knowledge, hardware to have a separate 2.4 and 5 networks, VLANs, and other solutions to separate networks and wireless signals. I do/will, do you? Do you trust commercial companies to worry about your security? I don’t.
If someone wants to hack my ZWave network, by all means, go ahead and turn my lights off and on… I don’t know that I will ever trust the security of a physical lock to ANY electronic device whether it’s WiFi, ZWave or other. (And yeah, you can pick a lock, I know.)
One year ago I did the same. Before that, at home, I had 2 wireless network, one was for me and different devices and the second one only for the smart-sensors, cameras and so on. But when I tried ZWave, I’ve started to slowly shift from the WiFi connection to the radio. In the beginning, the main problem was with a connection, because of different sensors/hardware manufacturers, but I solved it with kaa internet of things platform. For the moment I have only home hub / switch and huge set of sensors around the house. And everything works well!
