Temperature sensor to measure central heating (CV leidingen)

Post by Bartb » Sunday 11 December 2016 12:58

Hi.

I am looking for a temperature sensor, supported by RFXCOM, which I can use to measure the temperature of the water in my central heating (CV-leidingen). Can anyone recommend a sensor for this?

I have found the following device, but reviews on whether it works in Domoticz or not, seem contradicting.

Temperatuursensor TFA 30.3139

Have a link or name of the product I can search for?
I need it to have one of these external connectors so that I can attach the sensor to the Central Heating system pipes, and it needs to talk to RFXCOM.

Today I installed two of these for measuring temperature of the pipes my central heating:

Both work with RFXCOM in Domoticz.

perhaps build a espeasy with some dallas sensors...
You can make with 1 esp a complete readout device for all of your cv devices..[ 10-15 sensors. ]
And for less then a 1 433mhz sensor. [ buy Ebay ]

I agree with the Dallas Sensors and ESPEasy, I use a NodeMCU with 3 Dallas Sensors, One Central Heating, One Hot Water
and One In the Fridge, (I had a problem with defrosting for no reason).

Cheap and cheerful, upgradable to more sensors if required, and so much fun to play with.
A lot of stuff that is doing my head in.

Is the one in the fridge battery powered?

Sorry about the late reply Matt, I have been busy.

The temp sensors are on a single ESP12 node mcu board powered by a mains 5v PSU.
Effectively, if the fridge mains goes off, all 3 sensors go off, so no need for a battery supply.

It's been stable for a while now.

Hi there,

After reading this thread I bought two TFA 30.3139 with the external sensor and have an original USB RFXtrx on the latest firmware (Type 2 1024) but it cannot receive any signals from this device. I am on 3.8153 of Domoticz. The RFXCom happily receives Oregon and other AC/ARC signals.

I contacted Bert @ RFXCom who asked me to use rfxmngr - unfortunately I have no Windows device handy but I used rfxcmd_gc and didn't see anything coming back other than the Oregon's.

I have disabled all other protocols but no joy.

Does anyone have any suggestions?

Thanks a lot

Were you able to get it working yet?
I have a similar sensor (TFA 30.3133) and have the following protocols enables for my RFXCOM transceiver.
One of the enabled protocols should allow you to detect/add the sensor.

Thank you - no but I know why now - I have the original RFXtrx433 so I lent the temperature sensor to a friend at work - he got it working but has the later RFXtrx433E device.

The excellent Bert from RFXCom offered a competitive upgrade so I will have a think or just live with them not being supported.

Thank you again!
