I'm assuming that you have a temperature diode (only 2 pins). Unfortunately they require hardware to bias them properly and do analog to digital conversions. The MX series does not have the hardware to use them. If you want a list of hardware that is available for the 1-Wire bus see
great .thank you very much . unfortunately it looks like if i cant find them localy here in japan ill have to order them and the shipping will cost more than buying 10 of them lol
hey, i bought a mx 212 about 6 months ago. i was reading modthebox's reveiw and it seemed as thoguh you have redone the mx212. can i hook up the new led's and temp probes to my old mx212?
The one wire device is not supported with the old MX222 therefore there is no way we can make it compatible. As for the LED Indicator, the pin-out does not match up.
