You could try resetting the Zigbee network (Developer Tools → Zigbee). Reset the smart plugs and then add the two smart plugs first and repair the three sensors afterwards.
You may need to recreate existing flows in which the sensors are involved.
Please also take a look at this article → Advanced Zigbee Troubleshooting on Homey
If that doesn’t work either, then I would recommend contacting Athom Support.
When Hue lamps are connected to a Hue Bridge, they are located in their own Zigbee network.
