Just a thought:
Should I install 1-wire temp/humidity sensors all over the house (which involves running wires everywhere) or use wireless sensors like the 228?
For example, the Oregon Scientific THGR-228N is actually cheaper nowadays (E 30,-) than a Hobby-Boards temp/humidity sensor (including housing costing E 37,-) and has better looks.
Although I prefer wired above wireless (no chance of radio-interference), the 228 has better looks, a display and is much easier to install. I have a RFXCOM receiver, so insert batteries, mount the 228 to the wall and I am ready to go.
A quick scan on the number of places where I would like to install a temp/hum sensor tells me I need a maximum of 10 units (give or take 2), but I will probably start with 1 or 2 units. Ten 228-units set me back E 300,-. Still a lot of money, but it saves me the hassle of running wires everywhere.
A few questions:
- Will the RFXCOM receiver be able to handle that amount of sensors?
- What is the average lifecycle of the batteries used in the 228?
- Is the 228 suitable for mounting in the bathroom (Or should I use an outside capable sensor?)
Als het niet gerepareerd kan worden dan is het niet kapot!

1-wire versus wireless temp/hum sensors
I have 7 Oregon Scientific THGR-228N in the Bwired house allready years before the Rfxcom receiver and the sensors are still working.
I have one in the bathroom too, till now no problem. You can use the additional Oregon devices as well like outside temperature THGR918.
It was a rather difficult job to decode the Oregon protocol
Advantage is also that you have the digital display for direct use. I use 1-wire temps for places where the wireless Oregon sensors are not handy like temperature floorheating and warmwater etc
You should see my rfxcom receiver at work, really busy and working like a charme.
Without a doubt, for me the rfxcom receiver is still the best Domotica product of the least years!

Jfn,
Could you please give me the URL where you have seen the Oregon Scientific THGR-228N for arround 30 Euros?
Soon I will be needing some here.
Thank you.

As far as i know, it also sends out battery status "low" or "high" the bigger oregons or the temp. readers from rfxcom i think have a more accurate battery reading. Never the less you can know when it needs replacement.

I think they even do not charge for delivery.

1-wire versus wireless temp/hum sensors
I was planning on ordering them there too. 1-wire is nice indeed for places where you can hide the sensors easily.
@wifi: I do not know how many you intend to order, maybe we can organize a powerbuy? Every Euro discount is another Euro you can spend on even more domotica-stuf ...
@Bwired / others: How do you store the data you receive from the sensors? I intend to do it this way:
The sensors transmit a signal about every minute. It is not like 1-wire that you initiate read-out of the data (pull), the sensors initiate a transmission (push) themselves.
I store temperature / humidity readings for every packet received in a temporary table (Let us say I miss a few packets due to interference, so I have 45 readings from one single sensor). At every whole hour I compute the average on all 45 records for the particular sensor and store that average value in the database as the current temperature/humidity for the past hour. Every night I run a job that cleans the temporary table except the last hour.
I like to hear from others how they are handling (or intend to handle) their wireless sensors.

1-wire versus wireless temp/hum sensors
The above (topic) list screen is my logscreen that shows everything what comes in on the RFXcom receiver.
Every entry is send to my homecontrol system which shows all my devices and status (screen below).
If the status is changed then I update the status grid if the status is not changed I update the date last received. On every device I can put a event where I can do several thing like sending a command to another device or tell it log it to a database or a combination.
Normally when the status is changed I log it in my database. Sometimes 1 record per hour which is being updated and sometimes all the individual records. For temperature I log all the changes because I want to make some graphs.

1-wire versus wireless temp/hum sensors
My main interest is getting things in a database and be able to draw graphics. I want to know what is going on in the house, maybe get an SMS-message on my cell-phone when a certain event occurs, so that I can decide what will happen and not let software decide for me.
I am not quite near the point where I, for example, want the curtains to close automatically if the temperature raises above a certain level. Maybe somewhere in the distant future.
I can easily implement event-driven actions using the software (XPL-Perl) I use for obtaining data from the RFXCOM receiver, so when I need it, it is there.
Knowing the temperature / humidity in every part of the house is something that is on top of my wish-list, so I will probably be ordering some THGR-228N sensors this or next month.

Bwired, thank you for the link.
Jfn. At the moment I need 5, but I will be needing more later.
I'm in the UK (and will not be back home for an other 12 days).
Can you wait till then?

I have lot of sensors from Oregon. Some of them are more than 5 years old.
The BTHR918N will give you also the Baro.

A couple of month's orderd the Oregon Scale and a couple of the THGR238's. Everything went well (from payment till delivery) the only "but" in this story was that they deliverd the RTGR328R sensors instead of the ordered THGR238's. After a small email conversation the conclusion was that this was the 'replacement' sensor because the other sensor was out of stock/delivery. Money back or keeping the sensor's was no problem with the guys. So be warned, if you want know for sure what kind of sensor you get deliverd you better can email them before you order.
My 2 cents.
