In a Chișinău flat the ERBS puts an up/down/stop button on the wall while the MINI-RBS module behind it handles control through eWeLink.
What it is, who it's for, what it does
About this product
The ERBS is the official enclosure that turns the in-wall Sonoff MINI-RBS or MINI-ZBRBS module into a complete wall switch for roller shutters and blinds. The polycarbonate body bridges the module's S1/S2 terminals itself, so you no longer run extra wires to an old mechanical key.<br><br>The ultra-slim 21 mm profile drops into a European round wall box (Φ60 mm, Φ80 mm) and into an 86-Type box, and the clip-on fixing keeps installation quick. A micro-arc button gives a crisp press for up/down/stop. The material is fireproof, scratch-resistant PC in white. Note: the ERBS is only the enclosure — the MINI-RBS or MINI-ZBRBS module is bought separately.

Where it works
Use cases
The enclosure bridges the S1/S2 terminals, so the electrician runs no extra wires to an old key and keeps the wall box clean.
The 21 mm profile drops into a round Φ60/Φ80 mm box typical of older housing, with no need to replace the in-wall box.

Frequently asked questions
Does the ERBS include the smart module?
No. The ERBS is only the enclosure with a button; the MINI-RBS (Wi-Fi) or MINI-ZBRBS (Zigbee) module is bought separately and does the automation.Which modules is the enclosure compatible with?
With the Sonoff MINI-RBS and MINI-ZBRBS, the in-wall roller-shutter/blind modules.Which wall box does it fit?
A European round box Φ60 mm or Φ80 mm and a square 86-Type box; the 21 mm profile fits both.Why are no S1/S2 wires needed?
The enclosure bridges those module terminals itself, so you do not run separate wires to an old key.Is the ERBS controlled over Wi-Fi or Zigbee?
Not directly — the ERBS has no electronics of its own. Connectivity comes from the module inside (Wi-Fi on MINI-RBS, Zigbee on MINI-ZBRBS).What material and colour is it?
Fireproof, scratch-resistant polycarbonate (PC), in white.Can I install the ERBS myself?
Installation involves 230 V work in the wall box, so we recommend a qualified electrician.
