RFM95_sendWithRetry. Is this P-persistent CSMA?

Im just looking for clarification on
RFM95_sendWithRetry
```
const uint32_t enterCSMAMS = hwMillis();
		const uint16_t randDelayCSMA = enterMS % 100;
		while (hwMillis() - enterCSMAMS < randDelayCSMA) {
			doYield();
```
I think these parameters could have an effect on the RF traffic and Time-on-air right?

I would be keep to see the CSMA part explained or if its a particular type:

@eiten said in Saving last known good state, but not in EEPROM: utility meter in home assistant This is exactly what I am seeking! Thank you! PS I truly enjoy reverse translating! It teaches me how to better understand my first language and it gives me alternate words to use in searches. So a second thank you! "Regelmässiges Zurücksetzen" would be best translated to English in this context as "Periodic Reset". In the English version of Home Assistant it is called "Meter reset cycle" (I remember seeing "keep dry" translated as "do not take in shower with you"

Thanks for the answer. I meant that Mysensors has ESP32 support but only in terms of WIFI. It supports e.g. stm32 with ENC or W5500 modules - and the question is whether and how to add ESP32 support with LAN8720 module. I am not considering using ESPHOME or MQTT - I want to have native communication with the controller that implements my control schemes on its side. I try to program KC868-A16 but it does not matter - the question is whether such support can be added in a simple way.

Thanks, I'll keep this in mind if I decide to debug it. I realized that I am also tired of patching the gateway through to the doctor container inside an LXC so now I am looking at creating an esp gateway. Just need to check if I can find a pcb on here. Thanks again!

@OldSurferDude well, the ESP8266 is limited to 4 TCP clients in arduino IDE. This can't be really increased. I did som experiments and you can set it up to 15, but after the 5th client on my web server, I got a freeze. Maybe you got something wrong. #define MY_GATEWAY_MAX_CLIENTS 2 defines how many controllers (eg Home Assistant) can connect to the gateway, not how many sensors/MySensors devices. And yes, you can have multiple TCP gateways in HomeAssistant. I got an NRF24, an RFM95 long range and a RFM95 short range gateway (all based on ESP32) on the same Home Assistant. Regards, Edi
