Blue Series 2-1 Signal / Routing / Performance Issue Troubleshooting Thread

Just my luck. Received my 50 blue switches today and every single one is from either of the two effected lots. Debating even trying to install them at this point. Has anyone had these work with these lot numbers?

I have one currently installed and working, but it’s maybe 10ft from the coordinator on the other side of the wall. If you have a solid Zigbee mesh and you follow the general suggestions for Zigbee (usb extension cable, planned separation of wifi/zigbee channels, etc), you may be fine, but it’s really hard to tell offhand unfortunately.

Edit - I do have a couple others from those lots for clarity, they’re staying in boxes for now unless I need to do something specific testing-wise with them.

I’ve got 10 94:34:69 switches. I’ve installed 5. They were a little tricky to pair. I have some Ikea tradfri outlets/repeaters and I’ve had to place them very near the switches.

I just thought this was a zigbee range issue versus Z-Wave because my red switches have much better range. They work but I hope this can be fixed and I can remove the Ikea repeaters or place them where I want.

@Eric_Inovelli any updates by chance from the engineers?

Took one out of the pack to test out. 943469 ieee. Not much issue pairing, lqi listed at 61 shrug. We’ll see how it goes

Of the 10 switches I ordered I got
4 94:34:69
4 38:5B:44
2 04:0D84

I have installed 5 switches
1 I can not get connected and 4 seem to be working but I haven’t checked the signal strengths.

The final 4 are on hold until I hear more. The most critical spots (the 4 that are working) that i was dying to put switches in are working so I can wait out the rest. I know Eric is doing his best and will get to the bottom of it.

I should have checked the forum before wasting hours. better yet, Inovelli could have sent an informative email out to all buyers. (Why didn’t this happen?)

For two years I’ve had close to zero issues with Zigbee. I went through three different homes, through Conbee 2, Sonoff P, ZHA and z2m. Even zero issues with notoriously bad Aqara devices. My current place is large, I use 30 devices in remote locations and have no Zigbee issues.

Few days ago came the package I’ve been waiting for half a year. But then: Switches don’t pair. One of them paired but then connection lost. I wasted hours and started thinking I must be stupid.

At least I’m happy to see I’m not alone.

I hope Inovelli is putting all resources in tracking this down and I hope it will be firmware fixable.

If not, the switches are plain broken and hope we’ll get replacement.

Edit: I made it through the whole thread now and I see invovelli is actively looking at it and issue might be missed/wrong calibration of frequency offset. I’ll check my batch tomorrow and see if they match posted IEEE addresses

I’ll throw my confirming experience… all 10 of mine are in the 2 batches identified… I put one on the test bench today and it wouldn’t pair for anything… its probably 15 feet from my Hubitat with no other zigbee device close by, so it would have to communicate directly with the hub. 10 tries, nothing at all.

Plugged a Zigbee outlet in the plug on my test bench, paired instantaneously. Then it picked up the switch and paired with no issue.

I think this confirms I’m definitely seeing the same issues as above… If nothing else, hard to trust that these will work, which puts my install on hold.

Hoping there is a customer possible fix here and we aren’t waiting for new batches in December! I know the Inovelli team will make it right.

We are having a phone call with them tonight or early tomorrow morning to figure out what’s going on. I’m going to send out an email now as this seems like a bigger problem than we initially thought (I wrote in the email to them that it was wide-spread, but that was to get their attention… now I am afraid that it is actually wide-spread). We’ve been running our own tests behind the scenes and unfortunately we don’t have the proper tools to get to a proper conclusion (we have our theories, but I’d rather report the exact issue than speculate at this point).

The owner is aware of the issue and has stated they will replace these if this turns out to be a hardware issue:

My advice now is to either not install your switches or you can install them and if it turns out to be something that needs to be replaced, keep it in your wall as it still acts as a normal on/off or dimming switch until we can send replacements.

I know this is frustrating and I am working as hard as I can with the manufacturer for a proper resolution. I’m very sorry for the time wasted and WAF points that have taken a hit.

More about this tomorrow.

Thanks Eric for the update. If it turns out we need to swap for replacements for those of us that have these installed will we need to send in the old units first before replacements are sent?

I threw away all the old switches I replaced so hoping if replacements is needed they would be sent to us first so we can avoid not having any switches in the interim.

Thanks Eric! Hopefully it won’t come to 1:1 replacements – for those of us who already have them in the walls, we’d like to avoid that as much as you do!

Most of mine are now just acting as dumb switches/dimmers, and that will be fine until things get resolved. For the few that are wired no-load, I’ve got some Picos picking up the slack.

Thanks again for the updates and transparency - we’ll get there!

Yes, we will make this as easy as we can on everyone. This is not your fault, so we will make sure you’re taken care of.

Yeah, agree – but either way, we will replace the switch for you if you’re exhibiting this issue. I’d rather err on the cautious side and make sure everyone has the same switches we tested in beta and know are amazing.

No problem on the transparency, I promised you guys from the beginning of the forums that I’d share things good or bad. This just happens to be one of those bad times :/.


Stay tuned, I will provide an update as soon as I have one either tonight or tomorrow.

Just got around to checking the IEEE addresses for my 20 Blues. Including the 1 installed switch, I have
18 start with 38:5b:44
2 start with 94:34:69

Heading out to buy a Powerball ticket now… bad luck in the switch lottery means my number has to come up somewhere else!

I’m 30 for 30. Maybe we can split winning numbers.

:upside_down_face: sure I’ll take 3 numbers and you take the other 3.

I’m not choosing PB number though. Because if we get the first 5 and miss the Red ball, that’s not on me.

So this worked for me but your milage will vary… I had a switch that I could not get connected at all… I pulled a plug from a different part of my house, plugged it real close to my non working switch… and the hub found it and connected it for the first time!

I then moved the plug back to its original location and the switch is still working as of now. Could be a way for some of you to get the already installed (but not working) switches onto your network and see if they will stay connected.

EDIT: ok it fell off the network… so I had to move the plug back… and it worked again… so as long as you leave a plug close it can work until Eric finds the real fix.

In case anyone here wants to quickly look through all their switches (without taking them out of the box to inspect the sticker inside) and has an iOS device, I made this shortcut that scans all the QR codes and writes them into a CSV-formatted icloud Notes document: Shortcuts It’ll do max 100 at a time, but you can re-run it as often as you like.

Just scanned all 40 of mine, and welp, I’m 39/40 for afflicted IEEE address ranges.

I think I’ve managed to confuse myself…

Thus far, we suspect 94 and 38 are the sketch ones WRT signal/routing, but 04 seems to be OK – do I have that correct? Thanks!
