How to reduce dtu rebooting

[peter-tue]

Hi,

is there any way or setting to reduce the number of dtu reboots?

Quite early in the morning I have already 394:

• while writing -> 410.

My dtu has no internet access and the 'cloudPauseActive' is set to false.

Any help ?

... to the evening it grew up to 1270 reboots!
How many do you have ? Is is dependent on the DTO RSSI or any other factor?

[ohAnd]

it's difficuilt to interpret the data if you changed the code without knowing what in detail you've changed...
the connection is usually disconnected by the dtu due to whatever problem - mostly in my experiences by a weak wifi connection
dtuGateway only closes the connection activly (search for disconnect( in dtuInterface.cpp) when

• IP of dtu is changed by setting
• cloudUpdate pause started
• if there is a timeout of txrx observer

Could the DTU time possibly be set with the 'SetConfigResDTO()' command ?

as already mentioned: nothing to see also in other similiar projects how to set the dtu clock

I also blocked the 'Set Power Limit' since I don't want this to be changed (- can not see any reason why this should be changed on a 800W inverter?).

to this - check discussions for this or google regarding "zero-feed-in"

Sorry, but I have (at least ;) ) one more question. Do you think the DTU can handle two ESP32 dtuGateways (one in production- the other in debug-mode) running at the same time without being 'confused' by the two incoming requests?

[ohAnd]

In my knowlegde - the dtu can handle only one connection at time. If you have already one connection and try to setup for a second connection then the first one will be disconnected.
The protBuf interface needs at first a connection and then you can send a "reqeust" - is not a "normal" rest api with web based connection handling.

Thanks, good to have the opportunity to ask such an excellent expert.
