Would suggest that you do NOT look at workouts by Body Part Splits. Why only Deltoids? Why only at Home?
To be able to discuss more at length, need to know some details for the above questions.
Anyway, generally speaking, Barbell (Free Weights) Exercises (Compound Exercises that work your Whole Body) is something that you can do from home (provided you buy Barbell, Weights, a Power Rack)… You will also need to learn how to perform these exercises.
You will need to design a Training Program (do it yourself, if you know what you are doing. Otherwise, contact a Qualified Professional… If you need our help, contact us.
Squats, Deadlifts, (Overhead) Presses alternating with Bench Presses, Power Cleans and Chin-ups should all be a part of your Training Program.
The (Overhead)Press is simply THE BEST EXERCISE for your Shoulders. Bear in mind that this is not only for your shoulders, but does workout a LOT more muscles in your body, than just your Shoulders.
Along with this, Bench Presses (which should be alternated with Presses) are an EXCELLENT EXERCISE too.
Beware of the usual GYM workouts which ONLY do Bench Presses. If you only did Bench Presses, Without (Overhead) Presses, you WILL develop Muscle Imbalances in your Deltoids. So, be SURE to include (Overhead) Strict Presses (Not Push Presses) in your Training Program.
Note also that Body Weight workouts are a good start…way better than doing Nothing at all. To progress beyond what they (BW workouts) can offer, you will need to get into a Training Program, as mentioned above.
