RFXCOM and weather / temperature info

[sgtbean]

Hi all,

I'm pretty new to this RFXCOM stuff and I've been wanting to get a setup that monitors the room temperature in my living room. Additionally, I'd also like to be able to log the outside temperature and wind /-direction.
After some research I've come up with the following setup, which I'd appreciate feedback on:
- RFXCOM receiver ( 81003 see below)
- Type-3 RFXSensor (this one will be monitoring the living room temp. see below)
- Oregon Scientific WTGR-800 sensor (outside temp. + wind + humidity)

First question, looking through the forums and the RFXCOM website, I'm still a little confused as to what is needed. I get that I need a receiver ( w/ LAN) but I'm not sure what I'm getting. If I understand correctly,to receive both the Oregon sensor and the Type-3 I'd need the 81003 receiver plus the 80011 extra receiver module, right?

Second, in the future I'll be adding a second 81003 receiver that will allow me to monitor the utilities (gas, water, electricity) using the RFXMeter w/ RFXpwr. I understand from their website that I need an additional 2 optical sensors AND 2 RFXPulse modules to monitor gas and water usage, correct?

Finally, in the distant future, I'd like to add a water meter to monitor my hot tap water usage as well. For this, I can then add a second 80011 receiver module in the second 81003 receiver for the RFXMeter w/ RFXPulse module (70095), correct?

That would result in a setup of 2 81003 receivers, both with a second 80011 receiver module. One with both the 70095 RFXMeter and the 70087 RFXMeter, the other with the Type-3 RFXSensor and the Oregon WTGR-800.

I think I got it correct, but since it's all a little hazy when trying to figure it out, I'd appreciate some feedback from the professionals and correct me if I made a mistake?

RFXCOM likes your idea to order multiple receivers of the same type but this is not necessary if the sensors to receive are all within range of a receiver.

If you also want to control KlikAanKlikUit, HomeEasy or Harrison curtains in the future it is better to order the 83003 2 port LAN 433.92MHz receiver so that you can add a 70031 or 89031 transmitter module at a later time.
The 83003 receiver is able to receive the RFXSensor, Oregon WTGR800 and RFXMeter.


The 70087 RFXMeter + RFXPwr can have the 2 additional 70090 RFXPulse modules installed for gas and water.

The gas meter needs to have a small mirror on the least significant counter wheel. This mirror is on the 6 or the zero digit. For this you need the 70091 reflective optical sensor. If the gas meter has a reed contact you need the 70092 open-end cable to connect the reed contact to the RFXPulse module.

The water meter need to have a reed contact and you will need the 70092 open-end cable to connect the reed contact to the RFXPulse module.

OK, thanks for that clarification. I think I know what my thinking mistake was. Anyway, I've been taking a closer look at my water and gas meter and the gasmeter is lacking a reflective surface... I've also looked at the casing but I doubt it has a reed contact, or a location to put it. I did find a pulse module for a similar type of meter, but mine is old (1985, G4 Rombach) and I can't find anything confirming this pulse module can be used with my meter.

My water meter does not have a reed contact, but it does have a small wheel - like a sprocket - that is reflective with a red triangle on it. It also has a tine hole in it near the edge that passes over a small black area once every revolution. Would that be enough of a difference for the optical sensor, or is it not strong enough for that?

It is difficult to say if the water meter can be monitored and the only way is to test it.
