Hello,
Please make sure the router settings have not been changed.
If you need to reconnect IPT-2CH, please delete the offline IPT-2CH in the INKBIRD app.
Please power on IPT-2CH. Please press and hold the ‘Up’ button of IPT-2CH for 2-3 seconds to make the WIFI indicator light flash.
Please do not hold down the keys at the same time while powering on, it will reset the device instead of entering WIFI mode.
