## Description

Product Description Transforming into a Comfortable Smart Home The DUALR3 Lite work perfectly with your motorized curtains. Purchase a DUALR3 and DUALR3 Lite and use your voice commands to control your curtains with Alexa, Google Home, and other integrated devices. Track Your Energy Consumption Now you can monitor and analyze the energy consumed by your automation equipment and manage your usage. The DUALR3 features two integrated precision power meters that allow you to monitor the consumption of each channel separately. The Weather is Unpredictable It can be challenging to protect your home from hail or excessive sunlight when you're away. In the summer, closing the blinds during the hottest times will keep your home pleasantly cool. In the winter, you'll save on heating costs by insulating your home during the coldest periods. One Device to Control Two Lights The DUALR3 allows you to control two different circuits and monitor their consumption separately. This enables you to control two different lights on the same phase with just one device, saving additional energy and reducing your electrical footprint.

Review: Old Stock! Purchased in Jan 2025 but received the V1.x board with the old power monitoring chip. - It didn’t matter for my application but a warning to anyone. The Dual R3 has two different power measurement chipsets depending on the PCB version. I purchased from in Jan 2025 and received a v1.x (I think 1.6) PCB with the older chip. It is also a bit more complicated to flash with your chosen firmware because it doesn’t support diy mode. Hardware is great, 2 external switch inputs, 2 outputs, status led’s and a button, all in a neat package. UPDATE: Seller communicated well when I highlighted the version discrepancy and offered a refund as a gesture. In most cases it doesn’t matter which version you receive unless power monitoring is your prime reason for purchasing.
Review: Works nicely with multiway switching and home assistant - Works well for multiway switching where you cant just replace the switches with smart switches. Slightly too big to fit inside a ceiling rose so had to use a cowl and fit up inside the ceiling space. Integrates nicely with home assistant and as it two channel it can independently operate both our hallway lights from HA whilst also able to turn both on and off from wall switch. This will only work on 2.4ghz wifi so if you have band steering, you might see an issue. Do yourself a favour and make an IoT only wifi SSID and lock it to 2.4ghz if you can.

## Questions & Answers

**Q: Can this unit control two different lights in a two gang switch whilst maintaining manual button control?**
A: I mean to control them both doing the same thing at the same time, I do not need them to operate independently

**Q: Im using it for a roller shutter it works fine but the schedule does not work**
A: don't know the answer I flashed mine with ESPHome and use home assistant to control the schedule

**Q: Can this unit control 2 motors from one module such as velux windows?**
A: I don’t believe so, as the unit switch you will attach has an up and down function so that’s the two controls. If it was a light then you can do two lights. Once connected the App let’s you choose motor or lights etc
