    Brad, looks like the driveway is melting nicely. The nice thing about that system is no snow banks from the shoveling or snow blower.

    The big change we made this summer was to add pipes up by the road. So, the pile made by the snowplow on the road gets a whack of heat to melt it a bit. Each storm we watch and talk through if there are any things to adjust to make it run better. The 2 furnaces in the basement appear to be starving each other for air because the house is so tight. So, tomorrow we will directly hook outside air to the driveway furnace. then wait for the next storm to watch.

    Generally, when files are being added to an album (like from a web camera) I have the most recent first. If I save some of the images to another album, likefor a sunrise, i will have them in normal ascending time order.

    The cameras produce a file name with the format of
    LiVe camera# year month day hour seconds sequence number N

    So, the title, filename and URL all have this format for naming.

    I just found a very cool device! I will set up 4 temperature sensors and will have access through a browser to the temps. The plan is to do water temp going out to and coming back from each of the 2 melting zones. The unit will sit on the house' network and I will have access inside and outside the house to these readings. The unit also has 2 relays we may be able to use also.

    It is nice to find a product that comes close to what I wanted.

    That is cool stuff. Amazing technology. Hopefully that unit will save you money in fuel costs.

    It will sure make it easier to see what is happening to make adjustments and know when things are starting to go wrong. Their web site has excellent information - the product manuals are easy to find - the screen shots of the browser based setup pages is right there. You know exactly what you are buying.

    The module came in today and it is up and running. We have 2 zones in the melt system. Zone 1 does the main driveway. Zone 2 does the top of the driveway and the front walkway. For each zone i put a sensor measuring the water temp going out to the system (Supply) and another coming back in from the system (Return). The web page to view these temps is at
    http://longlake.homeip.net:8001 and it refreshes every 30 seconds

    An old web camera looking at the control panel (which all sorts of indicators on it when it is running) is at
    http://longlake.homeip.net:8002 and go to View Video.

    To test the new temp sensors I turned the system on. The "41" is the temp of the driveway at the sensor in the pavement. The target to get to is lower. But, to get all the areas melted the system will continue till the return water temp is the same as the supply. Then it knows it is not melting any more. Since the water going out is over 100 degrees, the sensor will get above the target. We have been moving the target lower with each storm to get to a point that works well - now we have the boiler putting out max BTUs. As the difference between the supply and return gets smaller, the systems starts to pull back and coasts - just pumping the water and not needing to add more hot water.

    When you looked at the temps the zones were cooling down and nothing was running. I saw supply temps around 112 and returns in the 80's. It will settle down over night into the mid 40's probably. The garage where the pipes are stays at 45 degrees.
