Cheap humidity/Thermometer sensor?

[Evelen]

Hi.

I want a sensor in all my rooms, but i don't have a lot of money.
can anyone recommend a decent sensor?

Z-Wave and RFXtrx433(E) is ok.

You asked for a cheap sensor. Z-Wave in general is much more expensive

Mine were inaccurate by a few degrees but as long as you have a reliable thermometer to test them against, you can easily make an adjustment in Domoticz. I have them everywhere. One in my vivarium is set to alert me if the temperature drops too low and successfully informed me that a heat lamp had blown whilst we were on holiday once. Well worth the £7

Received in the mail today, mine is also inaccurate by "a few degrees"

going to buy me a regular thermometer and calibrate

[markk]

Readings show slightly lower than normal human body temperature. If you were sitting on them at the time they seem to be working really well

[Evelen]

dont forget that this is celsius

PS: I tried to put one in the refrigerator and it turned colder, also I tried to take a shower and the humidity increased.
So pretty sure it's just a calibration I need.

[Evelen]

calibrated, works ok

I received 4 sensors last week, which look really the same (with Imagintronix printed on the front) . The model is wh-5. Behavior is the same, roughly 40 degrees to high. Humidity looks alright though.
Today I've tried new beta firmware (version 249) for thr RFXtrx433-ext, but no improvement.
Maybe this link can help (looks the same device): https://www.pitt-pladdy.com/blog/_20131 ... for_WH1400_

mhm.
Mine is also WH5

idk if it is the same device, probably I think.

If it helps, I have 6 of these running with Domoticz for over a year now. The 40°C correction is easily made and I have checked against a calibrated sensor. They work really well.

I've bought a cheap temperature sensor from Ebay and can confirm that it is compatible with Domoticz.

Pros:

• Recognized as 17 RFXtrx433E 6C00 0 Olohuoneen lämpömittari Temp Viking 02811, Proove TSS330.
• Low cost (8,89 euros).
• Uses standard AAA-batteries.
• Works straight out of the box after enabling 'FineOffset/Viking' protocol in RFXtrx433E.
• Accurate.

Cons:

• Does not have a humidity sensor.
• Does not have any jumper switches.
• Delivery to Finland took 10 days.
• The case is made of ugly-old-looking yellowed plastic.

The manufacturer seems to be Fine Offset Electronics Co.,Ltd (http://www.foshk.com/). I've ordered three more sensors to monitor more rooms.

UPDATE 9th December 2015: I've received three more sensors. They all work perfectly. Delivery took 17 days.

anyone else have problems with WT1285 if it is outside in cold wather?
I have 7 sensor in the house, works 100%.
But the outside sensor stopps working and I dont see it in 8-15 hours, and than it respond again and so on.
when i put it in the house it works fine.

Temp: around -3 - 8 celcius

Hi

I received one of these devices today (along with my RFXtrx433E). The RFXtrx433E is up and running (connected to a couple of LightwaveRF devices and my Energenie plug sockets) but I cannot get it to pair with the themometer. It's a WH5 device as shown below, I've put the batteries in and enabled the FineOffSet/Viking protocol, am running the latest firmware (1007) and have put the device right next to the RFXtrx433E but it will not pair.

What am I missing?

[b_weijenberg]

Is this sensor in the supported devices list? Please see chapter 2 in the RFXtrx User Guide.

[DJBenson]

Not specifically now but this exact device has been used by many members.

Did you get this working? I have ordered one and on the latest 1007 firmware and can't seem to get the WH5 to be recognised.
