We 3D printed a sleeve that makes the M5 both wearable as a lanyard and allows the power button to be easily pressed.

Our customers use the M5 to send a MQTT command that briefly changes the content on a TV from cable/satellite programing to their own internal marketing images and videos.

Our issue was that running the command and then putting the device in deep sleep with the A button had a battery of just a few hours.

Using the power button worked but it is hard to push especially when worn around the neck.

This sleeve has solved the "mechanical" issue with trying to actually use the power button.

We are getting several days of battery life which is more than perfect.

@lbp-of-mo The latest UiFlow 1.9.6 version now works perfectly with HiveMQ as it has the missing QoS field. Thanks to everyone that helped me out with this. - Paul

I am using the M5Stick C Plus to send a MQTT command. Currently I have it programmed to send the command and then power off. If I understand correctly it is actually going into deep sleep mode.

If I use the power button on the side it wakes up and sends the MQTT command. This gives me great battery life.

Is it possible to use button A to perform this task as it is much easier to press than the little buttons on the side?

I could not find a "power on" in UiFlow.

My other option is to 3d print a simple sleeve that would make the side button larger / easier to press.

Thanks!

@javi - QOS 0 is what we use. Is there a way to adjust the UiFlow code to make it work as it did before? Or - Is there a different way to program the M5SickCplus to make it work with Hive? Thanks so much!

@felmue - I use the desktop 1.0.17 UiFlow version. Also, I did not reload the M5stick but it just stopped working. (??) Is there a way to access/load an older version of UiFlow to try to get this working again? Thanks for all you have done BTW.

Background: I found a digital signage offering that has both live TV and the customers content. We discovered that it can switch back and forth between the content feeds with MQTT commands.

We wanted a wearable button that would switch to the client content when annoying TV commercials come on. When we see a TV commercial it can be made to disappear with one press of a button. - FUN!

We decided to start with HiveMQ because will need fewer than 100 devices but need to sort them into user groups.

Even at 57 and with no programming skills I can grasp Blockly.

So........

Is there another broker similar to HiveMQ Cloud?

Is there another way to program the M5Stick other than UiFlow so it can publish to HiveMQ knowing that I have no skills?

We we turn on the M5StickC Plus and it automatically connects to WIFI
Connect to Hive
Display "Connected" for 5 seconds
Send command: {"operation": "layout/set", "parameters": {"layoutId": 2, "length": 360}}
Display "Published" for 5 seconds
Display Battery percentage for 5 seconds
Power off the M5stick. (This gives us 3 to 4 days of use on a single charge)

This has been a fun project so far - A few weeks ago I did not even know what MQTT was!

@ajb2k3 Thanks so much! This worked perfectly on my M5stickcplus. We have been testing this about a week with no issues other than battery life.

Today for some reason it just stopped publishing the message. If we try it from MQTT.fx it still works. Now I am just confused. Could HiveMQ cloud have made a recent change that effected how this works?

This is the first time I have "MQTT'd" or used the M5StickCplus and until tonight it has been a hoot!

The M5sick still looks like it is functioning as it did yesterday. Is it possible it failed in someway? I have burned it and reinstalled the UIFlow program to no avail.

Thanks in advance BTW!
