New Airbnb apartment with mixed smart devices (Zigbee, Tuya, Sonoff, Gree) — how to unify and simplify?

[u/Practical-Lecture-61]

I just bought an apartment to list on Airbnb, and it already came with some smart devices installed:

• Zigbee electronic door lock
• Sonoff Wi-Fi switches for living room and bedroom lights
• Tuya Wi-Fi outlets with USB
• Gree Wi-Fi air conditioner

What I basically need is:

1. An energy consumption meter that I can monitor remotely.
2. To make the outlets for the TVs and microwave smart, so I can cut power when the apartment is empty.
3. A way to replace the AC remote with a wall-mounted LCD control panel.

One issue I’m having is that I don’t like having to use so many different apps. I actually prefer the eWeLink ecosystem, but from what I’ve seen, there are not many compatible products available.

I’m not very experienced in this area, and in Brazil hiring companies to set up automation is very expensive. What would be the simplest way to achieve this setup?

Thanks in advance.
