    Which Oregon Scientific Sensors??

    I am about to add a bunch more OS sensors to my HA environment. I have 6 THC-138's that I got CHEAP (wish I had gotten more!) but also want to include humidity.

    With a number of models available, with and without displays, I am wondering which models are the favored and/or which ones are the most reliable?

    I think I would like the ones with the display so I can use them locally, but there are many old and new models of these and I don't have a good idea if any are better than the others.

    Any ideas?

    Rob

    PS. Adding one to our reptile aquarium to be sure temp and humidity stay within limits for our quarter-sized ($.25) Gulf Coast Box Turtle. We have a water vapor volcano that can help increase humidity quickly if needed.

    I cant recall the exact models, but here's what I have:

    temperature only - no display - highly reliable
    temperature/humidity - display with switch for F/C - somewhat reliable
    temperature/humidity - display in C only - not reliable

    For the last one, I get more "Communication Failures" than I get readings and my test unit is maybe 10ft from my wiring closet. I've tried all 3 channels to no avail.

    I have one of the temperature only units in my attic. I almost never get "Communication Failure" and it gets to nearly 130F in the attic

      RTGR328NA or a THGR122NX???

      Thanks Rob. I know the C only ones mentioned and am staying away from those. I just don't know the OS product line well enough to know if I should get a RTGR328NA or a THGR122NX.

      Anybody have a preference?

        Rtgr328na!

        Got the RTGR328NA's and they are pretty neat! They work well and seem to transmit farther than the THC138's I have.

        Only worked with them a few days, but so far a big thumbs up!

            Yes it is. It works perfectly. It has a clock as well. I don't need that function, but perhaps maybe the turtle and the dragon will learn how to tell time!

              Sorry for the ignorance, but how do you connect your RTGR328NA wireless temp sensors to your HomeSeer. What kind of receiver are you using and how many sensors it can accomodate. How about a plug-in in HomeSeer (HS) to acquire the temperature readings from multiple sensors and trigger HS events based on temperature?
              I am using z-wave temp sensors, which I am not happy with and looking to replace them all ( 15 e.a.) however I do not want to replace a problem with another problem.

                Personally, I use the ACRF2 plugin in conjunction with an RFX 433Mhz receiver, (www.cheapertronics.com) to deal with Oregon temp. sensors.
                I have more than a dozen sensors operating now with very few, if any, collisions.
                Real courage is not securing your Wi-Fi network.

                  Thank you Wadenut. What is the typical RF range between the OS wireless temp sensor and the RFX receiver?

                    Hello! What is the Oregon Scientific sensor model that you want to read?
                    rfxcom devices are very expenssive... I can try to do something cheaper...

                    Thanks.

                      Oregon Scientific is cheaper. And supported by RFXCOM.

                      But all to it's own use. RFXCOM sensors are typically more advanced than OS.

                        Guys

                        As a rough guide, I have found that Oregon sensors that ony have a single 1.5v cell have a poorer transmit range.

                        Obvious when you think about it....

                          The RFXSensor can be received by the W800RF32 receiver.
                          There are 310MHz (for US&Canada W800) and 433.92MHz RFXSensor versions.

                          The RFXSensor can of course be received also by the RFXCOM receivers but the Oregon sensors have a lower price thanks to Chinese mass production.
                          The RFXSensor can have up to 7 low cost DS18B20 1-Wire sensors connected (using a 3 wire cable)
