Needed: Payment activates switch

[jondelee]

Hi,

I want to allow users to use a washing machine for 30 minutesby making a payment. I have the relay installed and working with a 30 minute countdown and I can actuate it with the tuya app, so the electrical part is done. I see that there is a Stripe integration and that might work but I don't want to reinvent something that someone has already done. I would like to have a simple qr code that a user can follow with their phone, make a payment, and that will tell Tuya to activate a switch.

Does a solution for this already exist? It doesn't have to be Stripe for the payment - in fact Zelle is preferred but any trusted payment method will work.

I also would like to develop a simple app for a similar rental equipment program - I am not a programmer and would need a pretty good framework to start with or hire a developer. Any referrals? I am in the US.

Thanks in advance!

this is a practical setup for pay-per-use device control, and i like that the relay and countdown already work through tuya. a qr that leads to a payment and then triggers the switch is the missing glue. has anyone built a payment-to-tuya webhook with identity checks and transaction callbacks? i prefer zelle for transfers, but solutions supporting card, crypto, or stablecoin are fine. are there platforms or integrators that handle kyb, payments, and device activation out of the box, or do i need a custom build? i'm not a programmer — pointers to low-code frameworks or us-based developers who can implement this would be appreciated.

this is a really interesting use case, and it connects well with what platforms like KEAworld.com
are working on. kea focuses on simplifying verification and compliance for licensed entities through a unified kyb framework, which could be useful if your project involves regulated payments or crypto integrations. by using a single verification system, you could automate the identity and transaction validation steps while keeping compliance consistent across payment methods. it might help you reduce complexity when connecting payment triggers to tuya-based device activation, especially if you’re aiming for a scalable, cross-border setup.
