So I am having trouble trying to do something with PLEG. I have an outside temp sensor which is on my OneWire network. I also have my MySensors thermostat bridge that will accept a value for the outside temp that will get displayed on the actual wall thermostat display. I just present a separate device for the outside temp as a place to set the value. I am trying to find a way to copy the value from the OneWire sensor to the thermostat outside temp device. It would be nice if I could do it any time the value changes, but I would also accept doing it say every minute. When I look at the options for the temp sensor, all I have is "if the temp goes above", "if the temp goes below" or "if the battery goes below". Because of this I am assuming that I will have to do it once a minute, but maybe someone knows how to do it on change of the value. My main thing is that I can't figure out how to copy the value over.

I thought it was more common for the ISP header to be 2 rows of 3 pins instead of a straight 6 pins? Not that you can't make that work.

@bjacobse I have just seen things in forums in the past like this where some users explain about the possibility of the microcontroller with the software based watchdog timer hanging to the point where the MC's internal watchdog hangs too. That was my basis for the comment.

What about a hardware watchdog such as this 555 based watchdog. A hardware based watchdog seems a bit more reliable.

I was hoping back then that Domoticz would get on the wagon and add support for these, but they never did. Unless they have done something recently, I haven't used Domoticz in a few years. It's good to know that there are others out there that do support this.

@alowhum Unless it has changed, the original sketch in the build section had this. Here is an example from one zone from my Vera setup.

Variable1 - 3 correspond to the V_VAR1 - V_VAR3 values.
V_VAR1 sets the zone run time when triggered automatically.
V_VAR2 sets the run time for when the zone is triggered manually from the buttons on the controller.
V_VAR3 sets the name that will be displayed on the LCD screen on the controller.

A few years ago when I was running Domoticz, I had some crafty LUA script with a custom sketch that let me do this to a point, but it was quite cumbersome. Getting my Vera Plus controller made this much easier.

@zboblamont Wouldn't it throw the count off if the people are in multiple pieces?

@alowhum The V_Var values are what let you set the watering times as well as the zone names that get displayed on the LCD from the controller side. Having this functionality would allow you to adjust the watering times based on weather data using a LUA or other controller based script. If you didn't have the V-Var values, you would have to hard code the watering times in the sketch and if you wanted to adjust them, you would have to modify the sketch and re-upload it.

@homer Not sure why you would want your Echo devices to handle the scenes, why not have your Vera take care of that? You could use the native scenes section of Vera or even better, use the PLEG and PLTS plugins. I am not sure about the Vera 3 capabilities as I run a Vera Plus, but I would think if nothing else PLEG should work.
