WS1700 cheap temp sensor

[ThinkPad]

Just registered to mention that [...]

That's the spirit, good job!

Any idea about the accuracy of these sensors? I am still looking for an indoor temp+humidity sensor on 433Mhz that works with RFXCOM & Domoticz.

I'm new to Domoticz. I bought myself a RFXtrx433E(v242) and also the sensor + weather station of Blokker.

I receive the following in Domoticz? I don't think the temp is 230,5 outside at the moment it's only 14,5 outside. I've seen it show different temperatures between 0 and now 230 and maybe up....

Did you solve this issue? I'm having the same problem with the RFXCOM E version, firmware 242 and the original WS-1700. I connected the RFXCOM to my laptop and the sensor is detected as type TH14 (WS4500). But in the topic I noticed their WS-1700 is detected as TH13. Could that be the issue?

I've had contact with RFXcom. They're testing a new firmware (v243) to fix this issue (incorrect values on WS-1700). It should be out soon.

Hey, thank you for helping solving this problem!

I bought the same thing. I enabled the Rubicson protocol on my RFXtrx433E (v. 242).
But nothing shows up in the Domoticz logs, after it says "accepting new hardware for 5 minutes".

Is there an additional thing that I should do? It says model 1790786 on the back.

[b_weijenberg]

a new firmware version 243 will be released soon.
contact support rfxcom.com for an alpha version.

[chimit]

If that will solve the temperature reception that will be great. I can wait until the release.
Thanks for the information.

On my model it also only says art.nr 1790786 and batch 2014/38.
Did you take additional steps to make it work? It doesn't seem to be recognized by Domoticz, with the Rubicson protocol enabled.
Could it be that batch 38 doesn't work and batch 39 does?

The one that DJSmiley linked to ('Weerstation met zender') isn't available anymore, link sends me to Blokker homepage.
What about this one: http://www.blokker.nl/nl/blknl/xiron-weerstation-2 ? (Xiron, Blokker articlenumber 1730751).
It shows a weather station, but it also shows outside temperature on the LCD, so it probably has a separate sensor for outside?

I have asked Blokker on Twitter if it has an external outdoor sensor. €5,99 is cheap
Edit (08/06/2015): Blokker responded that the external sensor is connected by wire.

[chimit]

Previous posts state that the EN6 version works and the EN7 version doesn't (I think).
Blokker says that they cannot tell you in advance which version you will get. So best is go to the store and check first before you buy.

Think i'll just wait until TX320 is back in stock at Kijkshop. These work for sure and also report humidity

New firmware version 243 with a correction for WS1700/WS4500 is available for download:

Bought the current €9,95 Xiron at Blokker. No luck this time.

LOTN/batchnr 408059
Art.nr. 1730807 / 17.30.807 (RS8751E3)

Changed it for the €14,95 Xiron version at Blokker, again no luck. Even while at this one 433mhz is written at the outdoor unit.
LOTNR/batchnr 408058
Art.nr. 1728957 / 17.28.957 (RS8706E3)
And EN7B at a small sticker at the outdoor unit

Has anybody seen wrong received sub-zero temperature values in Domoticz for these sensors?

My sensors give the wrong sub-zero temperature in Domoticz (i.e. -15 C instead of -1 C) , while they give the correct temperature on their own display (thus -1 C). At room temperatures both the values on their own display and the values displayed by Domoticz are the same and are correct.

I have two of these temperature sensors and both give the same results. RFXtrx433 firmware 250, Rubicson prototol, show up as Alecto WS1700, Bangggood.com, Domoticz 2.3530.


To me this looks like a protocol issue.
Any ideas to help solve this issue?

The new firmware works like charm.

Tried the same today.
Upgraded the firmware to 251, enabled the Rubicson protocol and accepted sensors for 5 minutes. Still no luck...

Xiron type EN6 is supported.
What is the type of your Xiron sensor?
