I did not found any way to update and run blender addon in blender without any moves inside blender. So, with this mode you can just press C-c C-a and your addon will be updated and reloaded automatically.

Pls, tell me if exist any bteter ways to do it :)

blend-mode.el:

(defvar addon-path nil
  "path to root folder of your addon")

(defvar addon-name nil
  "blender name of your addon")

(defvar blender-scene nil
  "blender name of your addon")

(defvar blender-updater-script-path "~/.emacs.d/addon_updater.py"
  "path to addon_update.py")

(defun touch-blender-file ()
  (interactive)
  (shell-command "touch /tmp/blender_reload"))

(defun run-blender ()
  (interactive)
  (if (not addon-name) (setq addon-name (read-string "Enter blender addon name:")))
  (if (not addon-path) (setq addon-path (read-directory-name "Enter path to folder with __init__.py:")))
  (if (not blender-scene) (setq blender-scene (read-file-name ".blend file path:")))
  (start-process "blender process" "blender buffer"
                 "blender" blender-scene
                 "--python" (expand-file-name blender-updater-script-path)
                 "--" addon-name addon-path))

(define-minor-mode global-blender-mode
  "Launch blender and feed it with addon."
  :global t
  :lighter "blender"
  :keymap (let ((map (make-sparse-keymap)))
            (define-key map (kbd "C-c C-e") 'run-blender)
            (define-key map (kbd "C-c C-a") 'touch-blender-file)
            map)
  (when global-blender-mode
    (setq addon-name (file-name-nondirectory
                      (directory-file-name
                       (file-name-directory buffer-file-name))))
    (setq addon-path (file-name-directory buffer-file-name))))

(provide 'global-blender-mode)

(global-set-key (kbd "C-c C-q") 'global-blender-mode)
