I use three of these IR transmitters to steer room fans, air condition and an electronic device which steers my pv module. It is the battery version, not the one with usb power.
I use it in Homeassistant with zigbee2mqtt.

It does not repeat IR signals as far as I know.

IT works perfectly fine even in spots where I thought that would never work. If something does not work it is a bad zigbee connection. (Which I have outside at the PV module control box)

If I recorded the same IR button from a remote control several times, it always gives a different code. But that does not matter because the unit which receives the signal does work even if it receives the same code over and over again.

No complains yet. (In use since 2 months.)

Funcionan perfectamente. Muy buenos acabados, la iluminación de los interruptores con poco luz funciona genial. 100% recomendable.

Fantastic

I love it! So easy to install. I mostly open/close vertical blinds with remote but using the app is just as convenient. Will buy more in the future as I need them.

The Finger i always wanted. :-)

Super great service shipping fast and on time. Customer service the best

Works perfectly well, it lets me set up scenes, and control devices directly allowing for local zigbee commands as well. The design is excellent, approved by my interior designer wife.

Very good item

I bought two of these to control lamps in my house, they're both working very well, I couldn't be happier with them.

I bought two of these to control lamps in my house and they work perfectly.

Excellent purchase .no neutral wire required specially for old house where is no neutral wire required

I bought one for our bedroom blinds, then another for the lounge room, then two more for the dining room. Last week, I ordered four more to automate our remaining blinds completely. This stuff is so addictive. They just work!

I really like the modular design and the touch and feel of these switches. I have quite a few and have been working flawlessly. I just miss one feature that is supporting decoupled mode. This could easily be delivered in a new firmware version. Really important if you also have smart bulbs connected to these switches.

I ordered two of these in order to get some sun on my plants while on vacation. The were super easy to install and work great. The only problem I had was after mounting them, I realized that I needed to reverse the motor - when I pushed UP the shade CLOSED. The product had this covered! and the directions were clear and super easy to implement. Love this product!
