Hi All I have been working for some weeks on building a completely local simple harmony hub integration that will Execute completely locally - not requiring additional software running elsewhere / on a different machine Edge based Simple bridge approach with a 1:1 hub binding (not trying at this …

Ok, this is me turning on/off my “Watch TV LR” activity. I will also let the monitor “run” and see if it captures the moment it goes offline. The log is going to pick up household usage but hopefully the moment it goes offline too. Dropbox

Thanks… There’s nothing in this log that suggests you were disconnected at any point. That is reality useful. I suspect smartthings has changed the way it treats child devices doing nothing… And after a while or treats them as offline. In reality, it’s impossible for a child device to be offline, a…

Oh yeah I ran that log right after the disconnect. I’ll keep the log running to try and capture an actual disconnect momment. When I get it I’ll post here. One thing I notice is for no reason from us, the Switching Activity Off command triggers every 30sec or so. Seems randomly.

I’ve just had a look through the code… I already have a routine that checks for an active connection every 60 seconds, I’m going to make a tiny change to explicitly set the device status to online at that point too. And set it for each of the child devices [Screenshot_20260907-223445] I’m presum…

Thanks for your work so far. Smartthings is actually rolling out a new update right now as we speak. Here are the links to what they are doing: [image] Hub Firmware and Edge Driver Release Notes - 0.62.7 Hub Firmware Release Notes We will begin rolling out Sam…

@lmullineux , I’m wondering if one of the recent SmartThings hub firmware updates may have affected Harmony Bridge Simple V2. The main suspect seems to be 0.61.6, since there were reports after that release of LAN/Edge devices becoming intermittently offline or commands not reaching devices. Since yo…

The connection doesn’t go stale… As seen in the logs above. The activity devices don’t actually have any connection or networking responsibilities - it’s all done by the parent hub device. I think it could just be inactivity at the child level, and st cloud or hub firmware changing the way that is…

I have just deployed a fix to the driver that will explicitly mark the hub device, and it’s child activity devices as ‘online’ every 60s at the already existing connectivity check. I cannot test that this resolves the problem reported by several users above @Jkinnick @AstroCat @GTOTIGER1 @danhvos @…

I just checked and all my devices are now back online. They were off all day yesterday and I have not reset my hub. So, it appears to be working… I’ll keep an eye on them. Thanks for checking it all out!
