Troubleshooting

I think this question is best answered by a chemist, not an electronics expert. I do not claim to know much about water chemistry other than it is very complex. Probably pool water does not have the buffering capacity as the buffer solutions do so the measurements are affected by all other chemicals, gases and stuff in the water. But again, this is just what i learned from my father who indeed was a chemist.

A few "reality checks" with ADCs : The precision of the ADC is limited to 0.1% at full scale (1024). This means that when measuring smaller values, it's less precise. For example, when measuring 1/10 of the reference, your precision is down to 1% already. Analog noise is usually in the range of 10mV is your circuit is carefully designed. Similar to above, it has a bigger effect on small values, but also on smaller references (1.1V is 3x more sensible to noise than 3.3V). Add a 10nF capacity in parallel to your 330k for better resilience. ADC is slow and needs time to calculate. Wait enough time between changing parameters and reading value (the Ardunio routines don't). I'd suggest you do a for() loop of 20x reading your ADC, and see the variation : mean(), std() and trend (for example last 5 - first 5). It could learn you a few things.

Hello, Some ware in MySensors website have info how to combine 2 sketches, i think one Arduino can handle all your need.

For anyone finding this: today I seemed to have the same issue, with cleared eeprom and with a test network made with two of the great red eByte radio modules. I read elsewhere on the forum it might be a memory issue.

Hi @leradis-plip, welcome to the MySensors community :) https://forum.mysensors.org/topic/10090/node-is-not-going-to-sleep-if-can-t-send-data might have what you need

@hermann-kaiser Thank you

Recompiled & uploaded the sektch and now I see the Temperature and Humidity values allright! Thanks again!

Any news on this one?

Make sure you don't have two controllers running. That will split the messages between them randomly.

Hi, for everyone who reads all of this, forget about the last few posts. I don't know why it works even when the Interrups are masked out on the radio, but it works now. The error I had occured because of the config of the OrangePi-Gateway. I removed: --extra-cxxflags="-DMY_RF24_DATARATE=\(RF24_250KBPS\) -DMY_RF24_BASE_RADIO_ID=\(0x00,0xFC,0xE1,0xA8,0xA8\) -DMY_DEBUG_VERBOSE_RF24" and wrote: --extra-cxxflags="-DMY_RF24_DATARATE=\(RF24_250KBPS\) -DMY_DEBUG_VERBOSE_RF24" Now I think I have an working OrangePi-Gateway without signing but with interrupt enabled. If there are new problems I will come back here. The next step for me is to activate signing again and bring the node into homeassistant.

That is my conclusion as well!

Hello, you can see recent article on range test of NRF24L01 PA LNA : http://domotique-diy.over-blog.com/2019/04/test-de-portee-des-modules-nrf24l01-pa-lna.html And see more about this on https://twitter.com/ThiDom1 You can found a demo link on the blog. It's in french but you can use google traduction ;)

Thank you for your all answers. I have made some tests and even if I don't have results for the moment, the best solution for me seems using (in accordance with @bgunnarb): MY_MQTT_PUBLISH_TOPIC_PREFIX ESP-topic/ESP-number Yes, it's can be a good idea @mfalkvidd

@gryzli133 MySensors is a community project. Anyone is welcome to wish for, or contribute new features. See https://www.mysensors.org/download/contributing for a guide on how to get started in case you want to contribute. As can be seen in the comment on https://github.com/mysensors/MySensors/blob/development/core/MyGatewayTransportSerial.cpp#L37 Serial prints are always deemed successful, regardless if the serial is connected or not (the Arduino can not know if someone is listening or if the sent messages are lost). There is no need to reconnect a serial port, so writing to serial never disturbs the rest of the code. That's why the serial gateway doesn't have any problems with disconnections. I am not familiar with the mqtt code, so I don't know how much effort would be required to develop a solution. Hopefully someone familiar with the mqtt code has som spare time to assist you, in case you need help.
