I was looking into IR blasters to control my old dumb tv that the fire stick will do everything but turn on and off when I realized that I might be able to solve the issue of my robot vacuum not having any ST integration and having very limited integration with Alexa (only auto clean) but since it has a remote I figured with a learning IR blaster I might be able to use it to automate it for any of the buttons that are on the remote. I know the switch bot hub 2 has an ir blaster but I couldn’t find it if it was learning. I’ve also looked at broad link blasters because they are so cheap. Does anyone have any suggestions? And my tv is in a different room from the vacuum so I’m assuming I’ll have to have two blasters but are there any limitations to how many devices a blaster can work with or how many buttons you can learn per device or anything like that?
I use a Bond Hub to control many things. It does both IR learning and RF learning. There is an Edge driver by @blueyetisoftware to make it run locally. Highly recommend this combo.
You just have the regular bond hub? Because the pro is more than I want to spend
Please see the existing topic:
ST IR Blaster….are ST device vendors a sleep at the wheel?
As far as what the SwitchBot hub 2 can do, the manufacturer site goes into detail in their FAQ:
As always, the first rule of Home Automation applies: “the model number matters.“ Different IR blasters have different limitations. You just have to do the research. 
As far as having two blasters, that’s certainly the easiest way since IR has to be line of sight to the receiving device. There are IR extenders which allow you to have a master device in one room, and then contact a satellite blaster in another room, but those tend to be a pain to set up and they are more intended for the very expensive, very sophisticated Wi-Fi to IR devices like global cache. I don’t think anybody would use one with BroadLink, they just buy a second blaster. 
Thanks Jd. As always you’ve been incredibly helpful thank you. And sorry for asking so many questions. I try to research the answers before I ask but I usually end up frustrated and lost in the weeds of irrelevant articles and information or I don’t understand what the information means due to technical lingo. Anyways thanks again
There´s also lots of cheap alternatives if you´re willing to use Tuya integration.
Been there, done that. 
it’s even harder to research these days since so much has changed with the new architecture.
Questions are always welcome here. Hopefully the community will be able to come up with some helpful answers. 
Yeah you’re definitely right about the architecture change. It seems like every time I search something I find a million posts about the topic but it’s all pre 2023 when the groovy ide was still being used. I spent like an hour reading about webcore before I found out that it was no longer a thing on ST lmao. But so far you and this community have been life savers. I’ve learned more from asking the community a few questions and searching other posts than I have from all the time I’ve spent researching. This community is probably my favorite thing about ST because it’s helped so much
I’ve been looking into the cheap tuya devices because my plan for my robot vac isn’t going to work so really I only need it to integrate with Alexa to turn my dumb tv on and off so if I can find a super cheap one that does that I’ll be happy
Yes, the regular Bond hub. The Pro version doesn’t even support IR.
I just leave the TV on and control on/off via a smart outlet, which is linked to Alexa.
