Straight forward to use. Click Start button and then Logon to the Cloud server. The App will pull down the connected borad comand from the Cloud server to activate/deactivate the corresponding relay.
You can download the App from Play Store using c123a30v as a keyword but this will not have true functions until we create a server logon for you. The App will tell you the board ID after the Start button of the App is clicked. Send the board ID together with your logon name to us and we wil setup the server account for you.

This includes 1 year server service fee. US$30 will be billed annually after 12 months.
As the App will download the command from the Cloud server on every 3 seconds and the possibility of not stable internet connection, this cannot be used for mission critical application.

The web UI offers

1. One-off relay activation/deactivation;

2. Scheduled activation/deactivation that can be used to activate/deactive the relay on a specfied time. The backend service will only update the status every minute, therefore there will be up to 1 minute delay under normal circumstance;

3. Each of the 12 relays can be configure either as One-off or Schedule.

Scheduled activation/deactivation overrides One-off.

The time input is an exact 4 digits string in HHMM (24 hours formate). If you need to schedule the relay passes across the mid-night, you need to use 2 relays in parallel.

The web program will only check this is a 4 digits string but no more. You need to pay attention to the logic of the input data.

The App supports CP210X, CDC, PL2303, FTDI adn CH34x chip.
