That’s strange. Do you have IDS/IPS, Pi-Hole/AdGuard Home or another filtering service enabled? OTA comes from the internet, so there shouldn’t be an issue with your local network.
Yes I do. IPS from Unfi and some strictly regional and ip-adress ranges firewall rules for my whole network and specifically gor my IoT network / Subnet & Wifi.
Is there any way to whitelist specific domains in UniFi? If you whitelist all shelly.cloud domains it should work.
I also found the IP it uses, it’s 35.242.243.136 for the OTA updates.
There is and I’ve working together wil shelly customer service almost 2 weeks on this until we both gave up and since then I gen any shelly firmware update I ask for (and can show I got the device) as a file. Normally they are not very eager/gappy to give it out of their hands.
Homey should automatically detect it and start using it in preference to the built-in BLE.
You can look in the app settings page and check it’s been found, plus use a web browser and point it at the ESP32 ip address, where you can click on the link to see the devices it has discovered.
Sorry that I was quite for so long.
Experiencing quite weird things / behavior / results with my 1st ESP32-S3-Zero /ESP32-S3-mini SwitchBLEHub. Its connection to my wifi network is not really persistent It likes to disconnect and connect every 8 -11 minutes.
I can’t see/find anything in the logs of my switchbot app that looks like its working connecting with my SwitchbotBLEHub .
Also I’ve foud several Contact)door-window sensors showing me weird times when they had an connection through BLE to my Homey. (Motion alarm : almost a year and contact alarm last time more than 3 months???
Is there a way to reconnect / repair the Switchbot BLE connection of a device to my Homey Pro 2023. Also its weird that it seems only affecting my Contact sensors and other switchbot BLE devices seem OK (so far I can see for now).
@Adrian_Rockall : what is your experience with the ESP32-S3-zero devices as SwitchbotBLEHubs ? Are they connected fine to your wifi ? and to the switchbot BLE ? How would you rate them ? would you recommend them or are these worse against the other ESP32 devices ?
I will test until Monday before I’ll give my 1st real review/user experience of them here.
BUT : THANKS A LOT FOR HELPING ME SO MUCH !
Have a nice day.
Do you have WiFi 7 APs? I also have this issue with one of my ESP8266’s since I switched to a WiFi 7 AP, I read online that many people have issues with IoT devices and WiFi 7 APs.
Does it also show “STA Timeout“ as the reason on your ESP32?
No WiFi7 and my other ESP32 devices seem working fine.
And sometimes its even getting worse and it last only 1 or 2 minutes until it connects & disconnects.
Is there any reason shown for the disconnects? Like “Station left” (AFAIK that’s when the device itself leaves the network) or “STA Timeout” (that’s when the device didn’t respond to the AP on time)?
where can I find this kind of information in Unifi ??
Did you take a look at my advanced/extended post with screenshots above ?
I might have found something similar :
The SwitchbotBLEHub is placed in my hall way in the center of my 120m2 apartment.
2 accespoints are about max 5 meters away(behind a wall in the 2 sleeping rooms). One is about 1.2m away on the ceiling.
Here some details about the access points Its trying to connect to :
If you need more or any specific details: just ask/tell me.
(The last 8 moth I bought all these AC-Pro accespoints (2nd hand = Marktplaats) to make my Shelley and other 2.4 Ghz wifi Smarthome devices “happy”. Since november almost never any of these devices are offline/unresponsible (due to its wifi connection). 
)
@Adrian_Rockall Does the SwitchbotBLEHub use any specific/ hard coded DNS server ? Because I don’t allow any others and especially not google dns through my firewall. Only a few DNS servers are white-listed in my firewall. And these are porpagated through my dhcp.
Are they maybe roaming between APs? Is there any feature to lock to a specific AP in Unifi? I only have 1 AP (Zyxel Nebula NWA110BE) so my network issue is likely related to the WiFi 7 issues.
By the way I just got my 2nd order of a 4 pack Switchbot EU plug mini in.
Its “only” 45€ for 4 at the moment which makes it 11,25 € a piece in the 4-pack at amazon.nl .
I hope to get a 3rd Switchbot presence sensor for a nice price next week at their spring sale. (I paid in december as a pre-order only 23€ a piece for my 1st 2 sensors)
Does anybeody know and/or has exprerience with these Switchbot presence sensors outdoors and or if they are working the glass/ a window like the Aqara FP1E does/specifies ?
I want one to use in a bathroom with a shower cabin that is made out of glass and maybe another I would place inside to watch my front yard through the window if there is any motion/presence too close (<2.5m) to my window.
Sorry, I have been to a funeral today, so not looking at my phone.
I must confess I didn’t have the ESP32 zero on for long as my home is covered by the original 2. However, for the few hours it was active in place of one of the others, it worked fine.
I have always separated my 2.4GHz access points with different IDs as a lot of older devices, including Homey, could struggle with automatically switching between them.
I have my 5GHz WiFi access points on the same ID as devices on that frequency are newer and work fine switching between them.
If the ESP32 is responding to Homey then you should see message in the log like these:
-
2026-03-05T18:05:43.741Z server got: SwitchBot BLE Hub! ec:6d:38:b2:67:ac from 192.168.1.209:1234 2026-03-05T18:05:43.741Z Registering callback: http://192.168.1.98:80/api/app/com.switchbot/newData/ 2026-03-05T18:05:43.742Z callback/add
You will need to set the log level to Basic Information.
My condolences 
and wish you well & all the strength you need.

Hello, I installed a Lock Ultra just before Chistmas and from that point until one of the updates few weeks ago I was able to use the Lock and Unlock card in flows, but now I get this error message; Missing Capability Listner: locked. Any idea why this happens? The same happen in the first Unlock/Lock sreen in the app.

Hello!
I’m now on v2.0.64 and since 14 hours app didn’t update data from temps sensors and from Presence sensor. Moreover after restarting the app, when I go to Presense sensor info I get this message (photo). Homey Pro updated to 12.13.0.
Any thoughts? 
The ENOTFOUND error basically means the app could look up the DNS record for the URL. I normally find restarting the app or rebooting Homey fixes that.
