Frequently asked questions
How does it differ from ReX?
ReX 2 supports photo verification (MotionCam detectors) via the Wings protocol and has an Ethernet backup channel. The regular ReX doesn't support MotionCam.Does it need an Ajax hub?
Yes. ReX 2 connects directly to an Ajax hub (not to another extender). It is compatible with Ajax hubs.How many devices and how many ReX 2?
Up to 199 devices per ReX 2 (depending on the hub). Per system — up to 5 ReX 2.Does it work during a blackout?
Yes. The backup battery gives up to 38 hours (up to 12 h with Ethernet on). It can also keep working over Ethernet if radio drops.Does it work with Home Assistant, Alexa or Google?
No. Ajax is a closed ecosystem; the extender is managed from the Ajax app, not via Home Assistant, Alexa or Google.What warranty and delivery do you offer?
24-month official warranty from Evrinet SRL (official Ajax importer). Delivery across Moldova, showroom in Chișinău at str. Columna 153.
