additional question: If a device is not updating this “lastseen” date itself, how do I automaticly PING this device. (with a script) Just about the same question like this. > [@How to automatically ping devices and use the result](https://community.homey.app/t/how-to-automatically-ping-devices-and-use-the-result/88845/3): > > Yes, I can ping battery devices. Look at this: [image] Yes, there is a battery status. But this doesn’t help much if the device stops communicating because of an error. The problem here was multiple problem. The chip itself died and it drained the batteries empty after just 30 days. ![ikea-routers-ping](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/6/56e2a0d6f12fc03d69df601b78e7a4c9a7783311.jpeg) ---

> [@Sharkys](#): > > IKEA Repeaters do not correctly update Last seen value That makes no sense 🤔 A “last seen” value is something that Homey determines. ( Repeater: “Hey Homey, you last saw me yesterday!” Homey: “No I didn’t, I’m seeing you right now!” Repeater: “…” ) ---

Yep and still, it doesn’t work with IKEA, I have no idea why. Now I looked on my Ikea Tradfri power socket - last seen two weeks ago :-)) Also there is some problem with storing / restoring this Last seen values upon restart - for some devices it’s reset upon restart, again no idea why.

What command is send from the development page with the “PING” button? After that the ‘lastseen’ date/time has a new value. ---

> [@Groetsels](#): > > What command is send from the development page with the “PING” button? You can try for yourself (replace “AA:BB:CC” with the full IEEE address of a device you want to ping): ```auto Homey.zigbee.runCommand({ "opts": { "ieeeAddr":"AA:BB:CC" }, command: 'PING' }); ``` This works from the Web API Playground, but not from HomeyScript, so it cannot be automated. ---

Hello Sharkey, trying to use the script as replacement to use Homey script 3.5.1 but get error: “Invalid token type: string. Expected: String” HomeyPro23 version 11.0.0 Would you know why this occurs since the script seems to be in use by others? ---

Hi Derf, I got a similar error when using the THEN card ‘Run code and return text-tag’ The script works fine though, only returning the output to the text-tag seems to be the problem ![Screenshot from 2024-05-19 01-48-07](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/4/04e4a5e383c456d0511400763a821636a5f841f2.png) > ![Screenshot from 2024-05-19 01-48-27](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/a/ba9544bfdd3d39ec08dbfaae6a3e14c5c793f87b.png) In Homeyscript console, and with the AND ‘Run code’ card, there are no problems. As script output, you’d use the generated HS tags as shown in my Timeline card: ![Screenshot from 2024-05-19 01-41-53](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/a/ca5d6b59f9cdc5b3bb138480c3323aa97446e00d.png) ---

Ah, I see, thanks Peter ! I have never used THEN, only as AND card 😉 However in my case, the error message is quite weird … `{"message":"Invalid token type: string.
