Loosing connection to Inverters (HM-600 & HM-1200)

[ropgenoo]

Hi community,
I'm using OpenDTU since 1.5 years and love the project. But since eta. 6-7 months, I've to restart OpenDTU three to six times a day. In the past everything ran rocksolid. I was able to receive data from both inverters in 10s intervall. Nothing changed since then, besides regular firmware updates. When I checke the now available "Funkstatistik" I see a lot of packet loss. For HM-1200 this is a few minutes after a restart about 50% and for HM-600 about 75%. The amount of lost packages increases over the day, which seems strange to me. So if the signal strength is not good enough, why is it getting worse over time? And why didn't that happen in the past?

Hope to get help here.

Please use v24.10.15 as we fixed some hard to find bugs. There may still be some issue with the temperature sensor of the ESP which can cause WiFi outages.

I‘ve updated to the latest firmware, but still no success. Connection, or package loss to the inverters increases overt time until no connection is possible and a restart is required. I‘ve a feeling that the NRF24 module is broken?

This would not be the first case in which the nRF module has a defect after some time.

I‘ll replace it tomorrow and check if the problem persists.
