Apple Watch Series 5 not detected

Hello, I set this up this morning and immediately ran into a couple of issues.

On boot, the device gets to the point where MQTT is set up then pauses for several minutes before it starts scanning. Is this expected behaivor? See log file below where there was no activity between 11:13 and 11:16.
It is not picking up my apple watch series 5 very quickly if at all. Occaisionally it will pick it up and provide data on the RSSI, but will stop updating.

I have the same issue with a series 5 on watch os 8.0 public beta

Hi @dcgrove (I hope you don't mind, I fixed formatting of your comment using `` instead of for code blocks.)

I'm not sure whether Starting scan... is only happening 3 minutes later, or is already running at 11:13 but just not finding your watch. I do know that the esp32_ble_tracker does restart from time to time, so you might just be seeing one of its restart debug messages.

I've not tested this on Series 5 watches (I only have a Series 3) so the Nearby Info message may be slightly different.

Could you change the lambda to the following? I'll need more debug info:

  on_ble_advertise:
    - then:
      # Look for manufacturer data of form: 4c00 10 05 XX XX XXXXXX
      - lambda: |-
          for (auto data : x.get_manufacturer_datas()) {
            if (data.uuid.to_string() == "0x004C" && data.data[0] == 0x10 && data.data[1] == 0x05) {
              int16_t rssi = x.get_rssi();
              ESP_LOGD("ble_adv", "Possible Apple Watch: data[2]=%#04x data[3]=%#04x", data.data[2], data.data[3]);
              ESP_LOGD("ble_adv", "  rssi %i", rssi);
              ESP_LOGD("ble_adv", "  mac %s", x.address_str().c_str());
            }
          }

This will print out bytes 2 and 3 from the payload. It'll probably find other Apple devices, not just your watch, so bring your watch close to the ESP32 so the RSSI is low, like -30 or -40 for easy identification.

Please post that log, and we can see what the difference is in Nearby Info messages.

BTW if you want to try figure this out yourself the rough structure of Nearby Info is at https://github.com/furiousMAC/continuity/blob/master/messages/nearby_info.md. We're looking at the Status, Action and Data bytes in the payload.

So I made the changes. Logs are at the pastebin link below. It is picking up lots of devices now which isn't surprising as there are several apple devices in close proximity to this esp32.

I also changed the on_ble_advertise back, and increased the logging level to verbose.

This is the log on reboot:

Thanks for the logs and pastebin.

I'm going to make the assumption that the strongest signal is your Watch, with an RSSI of about -50, and the mac address (at the time) of 47:4B:FA:C6:36:57.

If this is the case, then bytes 2 and 3 are 0x0D and 0x98, respectively.

In the original code on line 49 could you try changing byte 2 from 0x01 to 0x0D, and see if that detects your watch?

It should be:

if (data.uuid.to_string() == "0x004C" && data.data[0] == 0x10 && data.data[1] == 0x05 && data.data[2] == 0x0D && data.data[3] == 0x98) {

If that works, great! Then please take your watch off (so that it auto-locks.) The rssi should stop updating and after 90 seconds presence should go from Detected to Clear in HA. Put watch back on, unlock and detection should resume after a few seconds.

I will give this a shot. I was able to pull this from a BLE scanner app on y phone. Is it helpful?

Yes, that's helpful, thanks – Specifically the MODEL NUMBER STRING being Watch5,2 means that we can differentiate between multiple watches in the same house, provided they have different major/minor (5,2) revision numbers.

I made the changes you recommended above to line 49. Here is the log file. It is not picking up my watch.

Ah that's a shame. Perhaps as a next step you could try going back to the original 'debug' code I posted above to log out bytes 2 and 3 as well as the mac address and rssi. Place your watch (unlocked) and arm within ~30cm of the ESP32, so the signal strength is really strong (rssi about -30 to -50.) When it's much stronger than all other Apple devices it will be easier to find in the logs.

From there, you should see a pattern in bytes 2 and 3, hopefully something like 1 (0x01) or 13 (0x0D) for byte 2 and 152 (0x98) for byte 3.

Once you've found the pattern, then program that in on line 49 of the original code.

I'll ask my friends who has a Watch 5 this week and get them to help me debug in person, incase we don't come right here.

I changed the code, and I suspect this is my watch as it was the consistently the lowest RSSI and the closest device to the ESP32. Where do I find bytes 2 & 3?

[15:52:51][D][ble_adv:052]: Possible Apple Watch 11 152
[15:52:51][D][ble_adv:053]:   rssi -53
[15:52:51][D][ble_adv:054]:   mac 6A:5F:9D:C4:D0:CD

Byte 2 is the 11 that you see in your debug log (and byte 3 is 152.)

From this log and your previous one, it looks like the possible values for bytes 2 are 1 (for my watch series 3), and 11 and 13 for your series 5 watch.

Can you try this code to detect your watch? (From line 44 onwards.)

  on_ble_advertise:
    - then:
      # Look for manufacturer data of form: 4c00 10 05 YY 98 XXXXXX
      # Where YY can be 01, 0B, 0D; and XXXXXX is ignored
      - lambda: |-
          for (auto data : x.get_manufacturer_datas()) {
            if (data.uuid.to_string() == "0x004C" && data.data[0] == 0x10 && data.data[1] == 0x05 
            && data.data[3] == 0x98
            && (data.data[2] == 0x01 || data.data[2] == 0x0B || data.data[2] == 0x0D)) {
              int16_t rssi = x.get_rssi();
              id(apple_watch_rssi).publish_state(rssi);
              ESP_LOGD("ble_adv", "Found Apple Watch, rssi %i", rssi);
            }
          }

Good morning, here are the logs after making the changes above. Could the error messages w.r.t MDNS_networking be the issue?

Well, it seems to have started working. The watch was detected as you can see around 8:00:29, and I took it off which caused it to clear around 8:02:00 and it sent a state of 0. Still getting quite a bit of the MDNS errors so I am not sure if that is normal or not.

That's fantastic news, I am glad that it is working!

As for the mDNS issue, I am not sure about that. I did a very quick search, and found an issue where it seems like the device may be too memory constrained; or something to do with the wifi network.

For example, I am using a wemos_d1_mini3 with HARDWARE: ESP32 240MHz, 320KB RAM, 4MB Flash and ESPHome says

Compiling .pioenvs/lounge/src/main.cpp.o
Linking .pioenvs/lounge/firmware.elf

Flash: [========= ]  85.4% (used 1567402 bytes from 1835008 bytes)

My wifi is using b/g/n mode. (Not sure if this is relevant.)

Does your device restart often? Or just give those error messages but otherwise work correctly?

This is what it looks like when I compile. I have this set up on two different boards thinking maybe the first was defective. Both take several minutes to begin scanning for BLE with the MDNS errors. If either actually start scanning, they pick up my watch fine for some time, then stop scanning.

So I am not entirely sure this doesn't have something to do with my wifi or esphome/home assistant setup. Both boards are currently plugged into my office, and both boards just started detecting my watch at exactly the same time. Log from the famlr board is below. You can see where it started working at 11:04

It could very well be a wifi/router issue. What confuses me is that you didn't have the mdns errors in your original pastebin logs. Maybe the ESP is connected to a different AP now? I also noticed in the pastebin that DNS1: 0.0.0.0, although not sure if that's helpful.

I tried decreasing interval and increasing window and removing the if statement so it finds all bluetooth devices to try overload the ESP but never go the mdns error.

If you have a BLE tag, you could try setting up a basic ble_presence or ble_rssi sensor as described in https://esphome.io/components/esp32_ble_tracker.html, and see if you get the same issue. If you don't have a tag you can use your Apple Watch until it changes its mac address. Use this debug log to find its current mac:

ESP_LOGD("ble_adv", "Found Apple Watch (mac %s) rssi %i", x.address_str().c_str(), rssi);

I found the MDNS errors when watching the logs after I flashed it over USB with esphomeflasher. The log viewer in ESPhome does not show the mdns error for some reason. I can't get it to flash OTA at all as it says the peer has reset the connection at about 20-30% completion. Both boards have been plugged in all day, and were working this morning. You can see from the graphs below of the RSSI values that they stop picking anything up around 12:15and then start working again around 3:40. famlrgraph office graph

Maybe there are too many BLE devices detected and not enough time to process them all? I managed to recreate the "not able to upgrade via OTA" by setting interval from 1.2s to 800ms, and mine said peer reset connection at about 60%. Perhaps running out of RAM to store firmware during download.

You could try increasing interval from 1.2s to maybe 1.5s or even 2s? And/or reducing window to 300ms.
Try also setting duration to 1min. The default time is 5min, and this is the time between seeing Starting scan... in the logs, so may remove the large gaps between finding your watch.
Or even remove the interval and window lines (leave as default.)

Ref: BLE Tracker configuration

I've added some more debug, in case the problem with your watch not being detected is that there are more flags that the code should be detecting:

  on_ble_advertise:
    - then:
      # Look for manufacturer data of form: 4c00 10 05 YY 98 XXXXXX
      # Where YY can be 01, 0B, 0D; and XXXXXX is ignored
      - lambda: |-
          for (auto data : x.get_manufacturer_datas()) {
            if (data.uuid.to_string() == "0x004C" && data.data[0] == 0x10 && data.data[1] == 0x05 && data.data[3] == 0x98) {
              int16_t ac = data.data[2];
              int16_t rssi = x.get_rssi();
              if (ac == 0x01 || ac == 0x0B || ac == 0x0D) {
                id(apple_watch_rssi).publish_state(rssi);
                ESP_LOGD("ble_adv", "Found Apple Watch (mac %s) rssi %i", x.address_str().c_str(), rssi);
              } else {
                ESP_LOGD("ble_adv", "Possible Apple Watch? (mac %s) rssi %i, unrecognised action code %#04x", x.address_str().c_str(), rssi, ac);
              }
            }
          }

If you see the "Possible Apple Watch?" message please send me those debug messages.

Thanks for the continued troubleshooting! Here are the logs with the new on_ble_advertise code.

Thanks for the debug log. I have updated the code to detect the new 0x0a value:

  on_ble_advertise:
    - then:
      # Look for manufacturer data of form: 4c00 10 05 YY 98 XXXXXX
      # Where YY can be 01, 0A, 0B, 0D; and XXXXXX is ignored
      - lambda: |-
          for (auto data : x.get_manufacturer_datas()) {
            if (data.uuid.to_string() == "0x004C" && data.data[0] == 0x10 && data.data[1] == 0x05 && data.data[3] == 0x98) {
              int16_t ac = data.data[2];
              int16_t rssi = x.get_rssi();
              if (ac == 0x01 || ac == 0x0A || ac == 0x0B || ac == 0x0D) {
                id(apple_watch_rssi).publish_state(rssi);
                ESP_LOGD("ble_adv", "Found Apple Watch (mac %s) rssi %i", x.address_str().c_str(), rssi);
              } else {
                ESP_LOGD("ble_adv", "Possible Apple Watch? (mac %s) rssi %i, unrecognised action code %#04x", x.address_str().c_str(), rssi, ac);
              }
            }
          }

You'll see I added || ac == 0x0A to the if statement. If you come across any "Possible Apple Watch?" messages and you are sure it's your watch, you can add another "or" clause to the if statement.

I made the changes. Here is the log file.

You can see from the very beginning I started getting this message :

Possible Apple Watch? (mac 79:F5:61:70:E2:29) rssi -53, unrecognised action code 0x0f

I left the house at 15:33:04 and the messages stopped. I am not sure what the error at 15:33:33 means. I got home at 15:49:05 and the watch was picked up, but it looks to be a different mac address.

I restarted the esp32 with my watch off my wrist so that it was unlocked as I wanted to run a test. I put the watch on and unlocked it at 16:10:30, and took it off again at 16:10:59. I repeated this at 16:13:10 and 16:13:57. This has to match my watch as it was the only messages I received in the log while my watch was on.

Thanks for your ongoing debugging. I am sorry this is so painful, but hopefully we get it sorted soon.

... but it looks to be a different mac address.

Apple randomises the mac address to prevent tracking (for privacy.) This would be a lot easier if they didn't!

Yesterday I also found other actions codes 02 and 04, and with yours of 09 and 0f, it's probable that valid codes are 0x01 through 0x0F.

I've modified the code:

  on_ble_advertise:
    - then:
      # Look for manufacturer data of form: 4c00 10 05 YY 98 XXXXXX
      # Where YY can be 01..0F; and XXXXXX is ignored
      - lambda: |-
          for (auto data : x.get_manufacturer_datas()) {
            if (data.uuid.to_string() == "0x004C" && data.data[0] == 0x10 && data.data[1] == 0x05 && data.data[3] == 0x98) {
              uint8_t ac = data.data[2];
              int16_t rssi = x.get_rssi();
              if (ac <= 0x0F) {
                id(apple_watch_rssi).publish_state(rssi);
                ESP_LOGD("ble_adv", "Found Apple Watch (mac %s) rssi %i", x.address_str().c_str(), rssi);
              } else {
                ESP_LOGD("ble_adv", "Possible Apple Watch? (mac %s) rssi %i, unrecognised action code %#04x", x.address_str().c_str(), rssi, ac);
              }
            }
          }

So this have been running since about 8:30AM CST and has worked well. Have you seen an increase in battery drain on your watch? My watch was fully charged at 8AM when I put it on, and as of 12:43 CST it is at 38%.

I'm glad it's detecting your watch now.

I have not noticed any appreciable increased battery usage and I have 3 BLE receivers around my apartment. I put my watch on at 7am and 13 hours later it still has 70% remaining.

Jus to confirm the following:

esp32_ble_tracker:
  scan_parameters:
    interval: 1.2s
    window: 500ms
    active: false

active: false means only passive scanning, so the receiver picks up what your watch is already broadcasting, and should not increase battery usage.

You could try increase the interval. That may reduce battery usage but it will take longer to detect your watch. (It takes minimum 3 x interval seconds to change from present/not-present or vice versa.)

I have those same paremeters in the configs of both of my ESP32s. I will restart my watch to see if battery drain is resolved. It is entirely possible something else is going on. Thanks!

Hi @dcgrove Did the high battery drain continued after you restarted your watch?

A reset fixed the issue. It has been running on both ESP32's for nearly 48 hours now with no issues.
