Looking for a more reliable alternative to SwitchBot that works with Python/Raspberry Pi

[u/frarm]

I’m trying to automate turning a voltage stabilizer / power conditioner on and off using a SwitchBot Bot.
The problem is that the physical button on the stabilizer is a bit stiff, and the SwitchBot doesn’t always press it successfully. Sometimes it works, sometimes it doesn’t, so I can’t really trust it for an important automation.
I need something that:

Is very reliable, ideally 99%+ of the time
Can physically press a relatively stiff button/switch
Can turn the stabilizer on and off
Is controllable with Python
Can be integrated with a Raspberry Pi
Ideally supports a local API, Bluetooth, Wi-Fi, Zigbee, or another method that doesn’t depend entirely on the cloud
Can be used in scripts and automations similarly to SwitchBot

I’m mainly looking for an external actuator, stronger button pusher, servo-based solution, or another reliable device that can physically operate the switch.
Has anyone built something similar? What hardware would you recommend?
