Hi,

After a query in Mysql, I display the data on regular UI\_textbox and I would like to use ui\_switch do display by boolean fields data.

So far, no success, the ui\_switch never change according to received field value (true or false). IF I use a timestamp and sending true or false manually, the switch status change on the site dynamically.

Any idea what wrong I do?

Thanks a lot for your help

Yves

Here the switch config:

Add a debug to check the message you are sending to the switch and check that msg.payload is set to true or false

Particularly check whether it is boolean true or string "true"
