With Dave's help I have a small 1-Wire network operating along with my large Insteon system. I have a number of triggers operating to detect temperature conditions I want to react to but I would like to determine the value of the 1-Wire analog sensors that have triggered changes. The value are visible on the Device Status screen. I have looked at the various ph-get analog functions but I believe they are for Elk devices and the syntax is wrong for the 1-Wire structure in ph.
If this is left for future development, that is fine, no rush. I was just wondering of there is a way to do it now.
Having the ability to have ph make programmed decisions about 1-wire derived analog values would be very useful. I am fooling around with using photo-electic cells (voltage measurement) controlling blinds and Insteon dimming to generate a constant level of light in a room regardless of time of day and sun angle. I live in the Southwest where the sun is very intense and I am getting too old to keep getting up and down all the time to make adjustments.

Terry,
Sorry to take so long on updating this post.
You should be able to retrieve your 1-wire values by using the ph_getanalog or ph_getanalogcalcstat functions (they work for all Analog devices not just the Elk).
The ph_getanalog will go the actual controller of the device (you supply the PowerHome ID of the analog device) and cause it to query for the current value. The ph_getanalogcalcstat function does not go to the controller and instead just retrieves the value that already exists in the database. Since the 1-wire controller is actively polling and updating the database, the ph_getanalogcalcstat function would be the most appropriate.
Let me know if you have any problems with it.
Dave.

Thanks Dave,
I'll give these a try.
