Nedis blasters do not work currently, at 4.2025.! I bought three since they were my favorite ESP Tasmota flashable blasters! Our SmartHomes rely on IR blasters to run cooling and heating and many other things. While all three Nedis blasters were sending IR codes normally, covering 40 m2 area fine, two would not read 38 kHz NEC IR codes sent from a remote! Meaning: they could not learn codes nor be used to trigger actions by reading IR remote. For us, that meant we can not use our regular IR remote while watching TV/Video to make the SmartHome turn the amplifier on and to the correct TV input nor adjust heating and cooling - at the moment it is 37C outside! Plus, since the Logitech just dropped the Harmony remotes support, we will need blasters to interpret and translate remote codes in the future, when we replace some device. We use IR blasters for 10+ years at several locations with the 10+ year old IR receiver visible on our HTPC just behind the Nedis on the amp. This includes 5 years old YTF blasters (the original version of these Nedis ones) and multiple 2 years old Nedis. They are flashed with Tasmota firmware and many have easily added temperature sensor, as in included picture with 50 cm DS18B20. They work as a part of the advanced SmartHome program I developed. Blasters are crucial: the SmartHome server uses them to control heating and cooling using IR commands. I wanted to buy few spare ones, since the Tasmota ESP flashable blasters are becoming extinct. I do not want Tuya giving the Chinese access into our homes and Tuya can not run our SmartHomes at all. Nedis IR blasters are declared as reading 38 kHz only. My 2 years old ones read not only 38 kHz NEC protocol IR codes for our Home Theatre systems, amplifiers and SmartHome, but also 36-37 kHz Philips RC5/RC6 and Panasonic. All blasters can emit everything, that is never a problem. Receiving and reading IR codes outside the declared band, often is. Still, one can not complain that the 38 kHz device would not read 36 or 40 kHz remote. Our old blasters rarely misread IR command from excellent and very strong Logitech IR remotes. I set up 4 different blasters next to each other and HTPC for comparison. Normally, up to 20 or 30 IR commands daily would not be read correctly by a blaster. We press IR remote hundreds times daily, since we never watch live TV. IR reading may fail because of the sun, fast overlapping commands, moving remote and other reasons. That is normal but should never be noticeable! We never saw it as a problem for 10+ years! The first Nedis would not read anything! Sometimes it would read a NEC code when the remote was placed 2 cm from the blaster! The second Nedis would read some IR commands. It failed reading NEC 38 kHz commands multiple times in the first minute of use! It would fail reading more than 100 times daily, recognizing the protocol but failing to read IR commands, showing: "Protocol":"NEC" "Bits":0! It would never even see the Panasonic IR codes! Oddly, the third Nedis works normally for two months now!? These first two were returned. The single good thing I can say about them is: great Amazon return service! Someone here commented Nedis would not read IR commands, but the comment was useless without any facts. It could have meant the Nedis 38 kHz IR reading blaster failed to read Panasonic, Philips or Sony IR remote codes, but they were unaware of the different frequencies. This comment likely means my experience is not an outlier. Sadly, I would not buy this Nedis products in the future and can not recommend it. I may retest them after 6 months or so, hoping thy would fix flaws and return to the old high quality!
