Let's Control It

Hi all,

I have a new idea, and would like to track the reboots of my ESPs on a daily basis (clear variable right before midnight) in a dummy device due to this rule, which is working very well:

Code: Select all

on System#Boot do
  timerSet,1,60  // Set timer 1
endon

on WiFi#Disconnected do
  timerSet,1,60  // Set timer 1
endon

on WiFi#Connected do
  timerSet,1,0  // Clear timer 1
endon

On Rules#Timer=1 do
  Reboot
endOn

My idea was the following:

Code: Select all

on Clock#Time=All,23:59 do //will run once a day at noon
 Let,16,0
endon

On System#Boot do 
  TaskValueSet 6,1,[var#16]+1 //will this survive a reboot?
endon

I guess there is a slight mistake and this

Code: Select all

On System#Boot do

should ready as

Code: Select all

On System#Reboot do

Please correct me if I am wrong?

Merci already and kind regards
marstu

Variables do not survive a reboot, but task variables do.
So you could store something in a dummy task and try to read it at boot.

N.B. This is somewhat unreliable on ESP32, but on ESP8266 it does work, as long as you don't power cycle the node.

Ok, again not thought out correctly. Next try is something like that:

Code: Select all

on Clock#Time=All,23:59 do //will run once a day at noon
 TaskValueSet 6,1,0
endon
On System#Boot do 
  TaskValueSet 6,1,[Reb_Count#Reboots]+1 //will this survive a reboot?
endon

But how can I increase this task variable after each reboot? I guess I need something different to [var#16]+1, but what is exactly required? [Reb_Count#Reboots]+1 might this be an idea?

It is a ESP8266, I am not yet into ESP32s.

Tested and it is working as expected, thanks for the helpful hint.
