    Does Anyone Monitor Their Home's CO2 Level?

    I bought my sensors from All Electronics for $10 each, ( Telaire 6004 CO2 Modules) but they have sold all they had.  I have two extras and will probably put one outside.   I have one upduct in the ceiling and the rest goes out the fireplace flue and out all the bathroom exhaust ducts.

    Does Anyone Monitor Their Home's CO2 Level?

    I just calculate it using temperature and humidity  using this equation.       Loc = 273.16 /  ((Temp - 32) / 1.8 + 273.16)     Loc = 10.79586 * (1.0 - Loc) - 2.1836 * Log(Loc) + 2.2196     Loc = 29.9 * (1.0 / exp(2.3026 * Loc))     Loc =  humidity * Loc / 100     Loc = .622 * Loc / (29.9 - Loc)...

    VRC0P +3 secure commands quit working, non-secure commands still work fine?!?

    I'm sure you tried re-installing the firmware right?   That's what I would try.

    More LED bulb options

    I got 7 of the A19 Feit leds from Costco and they claim 22.8 years and so far 2 of them have gone out in 6 months. The reason I decided to try them is that when they go out I just take em back to Costco and get new ones. Can't do that at Home Depot I don't think.  Feit is Chinese junk as most...

    Want An Analog Light Detector That Will Output 0 to 5 VDC depending on Light Intensity

    Heres an example of a light sensor. You would have to make an enclosure to house it. http://www.robotshop.com/dfrobot-ambient-light-sensor-1.html

    New wifi device. Looks promising

    They don't get delivered till around March. I just ordered one to play with, but they are way to expensive to actually use. With my home automation system I am able to send commands via email, so this device will work with my system. Did i mention that the twine is way to expensive???

    VRC0P +3 returns '<X001'

    Your VRCOP needs to be closer to the door lock. You may have a metal clad door that may or may not be interfering with the RF transmissions.
