Below is my solderless write test device. Just an ESP01 serial reader, with a reset button, some wires, and a pin connector.

Just bend the ends of the connectors forward to make the board slide easily, then bend them backward and to the sides to adjust the connection pressure and pin distance.

Tested on 10 modules without any problems.

Thank you, can you also attach full JSON template from the Web App?

Yes. I will do it tomorrow. I will need to adjust one device because I don't use this like a smart switch. I use this like a counter. After tests, I will make another thread explaining the process and the configs.

Hello, there is my template used in this device. Maybe there is some room for changes. Like I said, I am a new user after all.
