I followed the same logic when deciding what kind of blinds control to choose building my house few weeks ago. Now I am in the planning of adding automation to it. Did you use Shelly Plus 2PM or are there any cheaper options to choose from (they seem to start at 30€ in my country shops)? Did they fit nicely in the wall switch socket?
I initially got the Shelly 2.5, now discontinued. The one that failed was changed to a 2 PM which is 31€ on Amazon in France (you could probably get better deals (I just checked with Amazon Germany and they are at 25€).
I mounted them right next to the roller (in the roller enclosure) and if I did not have that possibility, I would have done it close to the ground to have good access. I do not have a socket per see, rather a small switch on the wall not inside the wall, this is not permitted where I am)
I had a look at cheaper solutions in the past but gave up - I do not have a lot of rollers so the cost difference is likely to be minimal. I like the fact that they work well and it is really a kind of mount-and-forget kind of setup.
