Lately I've had reboots more and more often. The reason was always the hardware watchdog. Sometimes after an hour. Then I tried a lot to get rid of the cause.
Today he already runs 27 hours. It would be good to know if the latest changes have contributed, or if it was a coincidence. Of course, I'll have to wait a few days
to see if things will go on like this.Since I control only 3 shutters, and I transfer some data from and to the Homematic, there is no reason that the hardware watchdog reacts.
I control 6 relays only with longpulse and without delay. The whole thing happens time and temperature controlled. Since the current shutter positions are lost in a reboot,
I secure this on the Homematic. If a reboot has taken place, these values will be automatically restored. Now all I have to do is to fix all the shortcomings of the ESP.My actions:
Since I initially had software watchdogs, I tried it with short timer rules. Since then I did not have SWD's anymore. Coincidence? But i have enough HWD's.
Now I have an unused GPIO switched regularly:
on Rules#Timer=2 do
The intervals between the reboots became longer. But that was probably a coincidence.
The last measure was this: I ping my ESP from the Homematic every minute. Since then he has been running for 26 hours. Are disconnections now the cause of HWDs? After the reboot a connection is
immediately available. This is automatically restored without any problems. Because 10s after the reboot, the backed-up data is transferred back to the ESP.
The backing up and restoring of the data works perfectly well. I would like to show my approach here. So I'm not bored with it, but I wait, first, if someone is interested.
Just in this moment my ESP reboots. This time not because of hardware watchdog. Hooray. This time the reason is a new one.
And right now my cat has come through the chip-controlled cat flap. (RFID) But restoring my data has worked again. I'm glad.
