Welcome!

Which app version?  
Which protocol (like, zigbee)?

Issue seems to be reported 3 mo ago:

> I have dozens of ThirdReality products throughout my home. Great products and va…lue! About a month ago, I purchased the R3 Presence Sensor (Zigbee version, connected via Homey Pro 2026). The product works well and does exactly what I need for the area it covers. Having said that, each time Homey is restarted/updated, the Presence Sensor becomes unreachable. All of my other ThirdReality sensors work fine after a Homey restart/update. To address the issue, I need to restart the Homey App for ThirdReality (https://homey.app/en-us/app/com.thirdreality.app/Third-Reality/). After the restart, the device works fine again...until the next time Homey is restarted/updated.

But apparently it’s not fully solved.

Please use the developers’ preferred way to report issues, in this case we should use the github link 😉

No, it should report the first values after a few seconds/minutes, except for battery levels (when using zigbee f.i.) \> these can take up to 24h to appear.

Usually Homey doesn’t poll, sensors send changed values to Homey;  
in case something’s wrong with the connection, no event data arrives @ Homey (and there’s no error notification of any kind 🫣 )

For zigbee devices this is unfortunately completely normal @ Homey.  
It just doesn’t consider, f.i. zigbee, devices to be offline / unreachable after a certain amount of time of no data traffic
