General Discussion

Very simple solution, but I just put up a single flow (called watchdog of course) that subscribes to "hart beat" and value topics of items I am watching (in my case via openhab, but principle is the same for vanilla mqtt) and then have a "timeout node" for each item. Timeout node triggers if no message comes in in a predefined period (per item, some send data every few minutes, some every few hours) But each arduino node has defined hart-beat interval In my case all timeouts go to a function that formats a message in format "<itemname> not seen in <timeframe>" and that is logged and sent to an email once a day. But you can as well put it into a dashboard as Yveaux showed. I also like use of subflows whenever possible, but in my case all is happening on one flow and in two nodes, one that connects to mqtt hearbeat and one node that triggers if no data comes in (sorry I forgot the name, but it is a default node-red node)

I havent' seen but some one had the same probleme on the forum, and found the solution: [link text] https://forum.mysensors.org/topic/6096/problem-with-mysensor-library-on-arduino-ide-running-on-raspi/8 now i can download my sketch with the raspberry pi and i'm very hapy!

It works, thank you ;-)

@flopp electrokit is in Malmö and should be open today. Order pickup and you will have the parts later today.

@mfalkvidd Thx for the "quick and dirty" way. This at least is a starting point, but most things around that seem really to be hard coded (MySensorsCore.h: L77: GW Address is 0 is the point where the getNodeId() finally leads to). But if that really works there might be a way to wrap around that - but indeed this seems to be quite complicated. And indeed, you are right that having multiple nRF-GW's was possible ever since MySensors existed.

GW to node communication is not affected by Serial / MQTT / Ethernet interface with controller. With ethernet and MQTT you could actually connect more controllers to the same gateway, even on different computers. You can also have gateway running as a service on the RPI with radio directly on the GPIO and you can connect to is from wherever you have IP communication to the RPI (if you use the ethernet) or the MQTT broker (that could also be on another network)

@hek Thanks; maybe I'll try the inclinometer project.

@mfalkvidd Thanks for your valuable input. I think I got some direction to move on.

Sure it can be done, the only problem is the amount of flash of the pro mini that is limiting the amount sensors you can have when you have all securities enabled

Ive designed a NRF based mysensor remote with 14 keys, I want to use pin 2 for one of the key. Currently all pin work properly for key but pin 2 does not recognise instead it creates some disturbance in transmission. what i receive on destination node is unexpected. Is it possible to disable use of pin 2 . it looks like mysenso uses pin 2 for some internal use.

@gohan It's not like the drive stayed full for long. I usually ran with between 20GB and 40GB of free space.

@8667 That is inherently hard to state firmly due to so many variables. How much debug do you want, what libraries do you want to include, what software version do you plan to use, and so on.

@dakipro see here for a mapping of wifi and nrf24 channels: https://forum.mysensors.org/topic/4721/nrf-frequency-and-channels/5 NRF24 Channels 2..96 overlap with wifi. I personally would stay away from the high nrf24 channels (110+) as I've seen troublesome performance with clones. Channel 100 performs well at my place.

@wikibear - no problem :slightly_smiling_face:

@tango156157 said in ESP8266 Gateway Sending data directly to Cloud MQQT or Thingspseak...?: I wanted to check with the forum members if this is feasible? yes

what version of esp8266 definitions are you using?

It is served by google. You probably have an ad-blocker enabled in your firefox.

Hello, no there is no minimum frequency but for a serial gateway I would keep it at 16MHz to avoid any missed messages. It also allows a high baud rate on the serial connection. For battery powered nodes I use them mostly at 1MHz, there's not much interest going lower as you get no more gain in allowed voltage and not any significant gain in power consumption while the processing time increases.

@johnrob said in Why I quit using MySensors for actuators: Hi, I know I'm a little late to this thread. I'm just starting with MySensors and am learning by reading the posts. Currently I am waiting for hardware for my 1st gateway so I am not encumbered by details. I notice in all the reported cases the "problem" node is AC powered, while many of the "good" sensor nodes are battery powered. Could this be significant? It would be interesting if someone with a "problem" actuator node could put a battery operated sensor node in the same area. Hello, the problem is an actuator node has to listen to the radio constantly and can't sleep, so it can't last long on batteries...
