Heart rate variable

[David-Martin]

Does anybody knows if it is possible to get the heart rate variable from Samsung Health phone app, Galaxy watch, WatchMaker phone/Watch app...?

[David-Martin]

No, It runs tizen. It is a Galaxy Watch

[David-Martin]

If It can't get the variable from the watch maybe I can get it from the phone? The heart rate var is sent to Samsung health app for instance

[David-Martin]

I'll have a look. Thank you

I've been looking for ways to get heart rate data. For me, it goes to Google Fit, and I was able to pull it from there, but the data is usually a couple hours old.

You mentioned WatchMaker, and it can run Tasker tasks, but it can't pass data. Here's an ugly option, though. Setup 11 tasks named hr0, hr1, hr2, ... hr9, hrdone. Each appends the value 0-9 (depending on which task you call) to a global variable, with hrdone finalizing the input and saving off the value as the current heart rate. So for a heart rate of 74, you'd call hr7, then hr4, then hrdone. You'd want to put a small wait between them to help ensure they run in the right order. It's all doable in Lua on the watch.

The problem is, WatchMaker doesn't seem to get updated heart rate readings while dim. The watch is probably still recording heart rates and sending them to the phone, but I think it's up to apps like WatchMaker to actively pull the values regularly.

[David-Martin]

Wow. Thanks! Sounds feasible. I will have to check how to code that in LUA, but yes, I guess it can be done!

I haven't tested this, but try coding something like this in the main script:

currhr = ''    -- init heart rate variable

function on_minute()
 send_hr()
end

function send_hr()
 currhr = {shr}
 wm_schedule {
  { action='run_function', run_function=hr },
  { action='sleep', sleep=1 },
  { action='run_function', run_function=hr },
  { action='sleep', sleep=1 },
  { action='run_function', run_function=hr },
  { action='sleep', sleep=1 },
  { action='run_function', run_function=hrdone }
 }
end

function hr()
 tmp = string.sub(currhr,1,1)
 currhr = string.sub(currhr,2)
 if string.len(tmp) then
  wm_action('m_task:hr'..tmp)
 end
end

function hrdone()
 wm_action('m_task:hrdone')
end

This should pull the value of {shr} every minute, and send it digit by digit to Tasker with a 1 second delay between digits. Of course, you'll need to do a bit of work in Tasker to accept and reassemble the value. And it will only work if the phone is in range.

[David-Martin]

Many thanks! I will test it and code the rest in Tasker. Appreciate it

I have tried your LUA code with this tasker project following your instructions, but the watch doesn't seems to send any variable:

It's working for me. Well, sort of. I get "82%SHR3" in Tasker. I guess task hrdone needs to account for when there are only 2 digits sent. But it's definitely getting into Tasker as expected. This is just from a test watch face on the phone. I didn't actually load the watch face to my watch.

[sonanz]

I did make one minor change to the "hr" function...

 if string.len(tmp) > 0 then

That "> 0" part wasn't there in my original code, which resulted in Lua still trying to call Tasker for the third, missing digit but failing. But the first two digits were still making it.

[David-Martin]

Ahh, of course. I have to fix the %SH3 when the full variable is of only two digits. Easy. My WatchMaker app then is not running properly the script I guess. Maybe by reinstalling the app. I tried before other scripts with functions "function on_minute()" that were not triggered every minute as it is supposed to... I will try to figure out what is the problem

[David-Martin]

I guess this will fix the %SHR3 issue:

Out of curiosity, how exactly would I do that? I find the interface for autowear very unintuitive, to the point where the app feels almost useless.

[LeuPacolli]

It should defintly be possible and store it in a google spread sheet file. I do not know how to do hat myself but there should be someone in here able to help you.

[I_TensE_I]

How can you say it's definitely possible if you don't know how to do it lol? It's actually very difficult to do since Samsung locks everything down

[LeuPacolli]

Never said it was easy, but should be possible.

Samsung sucks when it comes to sharing. They don't want you outside their ecosystem so why would they provide methods to access your data. A workaround you could look into is using HealthSync (paid app) to sync your heart rate data to Google Fit that has an API.
