Unfortunately, I’ve been experiencing the same issue for quite a long time. Even when products are available, the stock is often very limited. For example, I currently use around 20 Aqara bulbs (GU10, RGB CCT) in my home. I was only able to purchase them by ordering a maximum of two at a time, and it took me about 2–3 months to get all of them.
Another issue is that when products such as the Aqara T1 Ceiling Light and Smart Light Switch H2 (4-Button, 2-Channel) go out of stock, third-party sellers often relist them at two or even three times the normal price.

To be honest, I really like Aqara products, but these supply and availability issues sometimes push me toward other brands. Unfortunately, I often end up encountering different problems with those products as well.
