Anywhere the ADC-S2000-T is in stock?

Looking to add a remote temperature sensor to my T3000 thermostat to keep the nursery at an appropriate temperature, but it appears out of stock everywhere!

Anyone have a suggestion on where to buy one? Or another sensor compatible with Qolsys IQ4?

That version has been discontinued recently by the manufacturer. They have a replacement, the ADC-S40-T. We do not carry them currently but I believe they have been widely released at this point, so you may be able to find them elsewhere.
