Hi,
since a few weeks I’m searching for a cheap (and easy) way to monitor the temperature and the humidity in my rooms.
Right now I’m leaning towards the Aeon Labs ZW100 as I already have some Z-Wave devices. What puts me of on these sensors it that they don’t have a Display.
Another way would be to use the RFXCOM binding and using off-the-shelf sensors for weather stations but the Cost for the RFXCOM Stick puts me off (100€) and I could not find any information if other sticks are compatible with the RFFXCOM binding.
Other Smarthome bridges do have nice sensors wich would fit my needs but I don’t really want to have “additional” Smarthome Stations.
Hi,
I have made very good experience with a JeeLink controller and appropriate TechnoLine sensors. One sensor (temperature and humidity) costs around 17 EUR and the controller about 30 EUR. I placed one sensor in every room and for openHAB 2 you can find a very good bindig here: https://community.openhab.org/t/new-jeelink-openhab2-binding/15018
The battery powered temperature + humidity sensors are $10 each.
You can add I think up to 30 devices to the gateway (but this needs to be verified…) like motion sensors, door contacts and wireless switches.
Although, you need a clunky smartphone app (poorly translated to English) to get things connected.
For the mysensors.org or the “Program yourself” Option: That is not my cup of tea - I envy people who are good with electronics and programming - but I’m not one of them. That’s why I shy away from those things.
The Xiaomi looks quiet good and cheap but the fact that the gateway communicates with some servers in the internet put me off. Nice to see that now it works without cloud access with developer mode. That beeing said: the Sensors don’t have a display so WAF would not have been as high :). Also they don’t have german Plugs as far as I see :(.
Thank you all for your assistance, it’s highly appriciated!
Hi,
I initially got two “Technoline Zusatzsensor TX 29 DTH - IT”, the german Amazon Page had a lot of reviews stating that FHEM works so these should work. As the JeeLink I went with the v3c: http://www.digitalsmarties.net/products/jeelink
I did not get to test them as the JeeLink is not yet here
I’ve bought a while ago the “original” JeeLink v3c from JeeLabs and I’m using the Technoline TX35DTH-IT sensors. Because they use a different data rate of 9.579 kbps you have to set in the JeeLink receiver configuration the following init command - what is now supported also in the JeeLink binding for openHAB 2:
0a 1r v
Today I would also prefer the TX29DTH-IT because with their data rate of 17.241 kbps they work directly out of the box - but in my understandig they have no further benefits.
You can find a very good overview of the sensors an the controller here (in german):
I use the Technoline Zusatzsensor TX 29 DTH - IT + JeeLink Solution and they are great and cheap. Second and third I would suggest a DIY MySensors oder DIY Souliss sensor nodes.
And I prefer RFM69HW over NRf24L01+ Radios, because 868Mhz can bridge a longer distance through walls than 2,4Ghz.
I have a number of these sensors around my house. They work great and also look the part, so score high on the WAF. Although they are not the cheapest, they do fit in very nicely indeed.
