If you use Alexa to turn on the TV, you’ll be able to control the volume for a short while after by simply saying, “Alexa, turn up the volume." Once that short period has ended, you’ll just need to say, “Alexa, turn up the volume on my TV” instead. If you're using a Roku box, you can even use Alexa to boot up certain apps. "Alexa, pause/play/stop/resume my TV" (Note: as we explain in just a moment, if you've used Alexa to turn the TV you'll be able to simple say, " Alexa, pause/play/stop/resume" for a period of time). It’s worth spending some time tweaking this to get it right. You could set it up so saying, “Alexa, turn on sports” will turn on ESPN. Similar to what you did above, you can use friendly names to load your favorite channels. On the next page you can select your TV favorites. You can deselect these if you don’t want Alexa to control certain activities. The idea is that it makes it easier to remember what to say.Īlso, note the check boxes next to each activity. For example, we have one that switches on the Xbox One, TV and dims the lights, so we chose “Play Xbox” as one friendly name to make all that happen - but you can add several different ones. Here you can set a friendly name for them. When you connect your account, the Alexa app will show you your list of activities taken from the Harmony app. If you used Google or Facebook to do so, you’ll need to do the same here. The app should guide you through this process, but you’ll need to use the same account currently tied to your Harmony system. Once you’ve found it, enable it.ĥ) Log into your Harmony account. Hit the Menu button at the top left.Ĥ) Search for the Harmony skill.

Even better, the Harmony Alexa skill has been much improved, making it much simpler to use.įor any of this guidance to be relevant you will need the Logitech Hub itself and an Echo device. What you might not know, however, is that you can use Alexa to take those controls out of the equation entirely. These findings indicate that the polar S 2O 3 group is a kind of NLO functional group with superior comprehensive properties, and has great potential to develop more NLO crystals with superior comprehensive properties.If you have a Logitech Harmony Hub, you’ll know it can completely change the way you control your TV setup, either using one of the Harmony remotes or just your smartphone. ![]() According to the first principles calculations, the polar tetrahedral S 2O 3 group is the main source for the SHG response of (NH 4) 2S 2O 3. As expected, it exhibited a strong SHG response (3.3× that of KDP), suitable birefringence nm) and a short absorption edge (238 nm). On this basis, a nonlinear optical (NLO) crystal (NH 4) 2S 2O 3 with excellent performance was synthesized. However, by theoretical calculations, we found that polar tetrahedral S 2O 3 shows great improvements in anisotropy and second order polarizability compared to SO 4 while the wide band gap can be preserved. It is generally considered difficult for traditional sulfates to exhibit strong second harmonic generation (SHG) responses and large birefringence values because SO 4 groups are nonpolar tetrahedral structures.
