I'm still getting this error on mysensors gate upgraded to 2.3.2.

@BearWithBeard said in mysensors regularly disconnect from HA:

Have you had a chance to look at the gateway's serial log when it lost connection to Home Assistant?

No this is on my list to do.

What version of MySensors are you running by the way? Maybe it's worthwhile to upgrade to 2.3.2 if it isn't already. Home Assistant is also up to date?

HA is 2010.09.0, I can't upgrade further until I upgrade to Debian Bullseye
Mysensors gateway is running 2.3.2, some nodes are slightly older.

The next steps that I would take would be to ...

• Check that both MySensors and Home Assistant are on a recent version

Done

• Watch the gateway serial log for any hints (using a remote debugging library or hooking it up to a server / RPI and writing the serial output to a file)

On my todo list.

• Ensure that the power supply is fine and maybe even replace it temporarily, just in case

Checked, all seems ok

• Consider adapting the gateway sketch to MQTT (or even serial) and see if the issue still comes up

Don't really want to do this, but will to as a last result once I've checked gateway serial log.

@keithellis I think I've got it refreshed now. So lets see if this fixes my disconnection issues. thanks all.

@electrik Yes I've found this post, but to be honest I don't no how to change the ESP8266 core. I'm flashing with the Arduino IDE and have used the ESP8266 Community Board. Is using version 2.7.4 of this board manager the same as using a v2 core?

@FarmerEd @BearWithBeard I tried to re-flash the wifi gateway, but it appears I am now stuffed. Apparently it is no longer possible to flash MySensors onto an ESP8266. Where to go now? It is possible to integrate NRF240L01 with a ESPHome gateway?

@BearWithBeard thank you, that gives me a few things to try.

@keithellis This is the log after I reload the integration in HA. Don't know if this is useful.

Looks like it was all working well up until the last line, then the socket closed. If you can help me understand what is going on, that would be great.

I grep'ed the log for "mysensors", so if this has missed any important information please let me know and I can have another look.
Thanks,

@BearWithBeard I've enabled the logging, I'll have to wait for it to drop off now, to see what it shows. Thanks for the info.

@BearWithBeard thank you, I’ll investigate further.

I’ve been using Home Assistant for a while now and have a couple of mysensors temperature/humidity sensors connected to the mysensors integration via a Wi-Fi gateway. Every so often, maybe once every one or two weeks the sensors stop communicating with HA. I use the reload command in the mysensors integration and they start working again. This was not too much of an issue, but I have a pulse meter measuring my energy consumption now and I don’t really want gaps in this data.
Any idea how I can trouble shoot this issue?

Got this sensor up and running now. Comparing it to my old clamp meter the kWh reading was reading 2-3 times higher, the Watts was about right. I added a 0.1uF capacity across the ground and data pins of the sensor and it is working well now.
The graph below shows the comparison of my two sensors. the old clamp meter is Energy previous hour, the new pulse sensor is Temp energy previous hour
You can see they are not aligned, until about 20:00 when I added the capacitor and they drop in line.

@sundberg84 Thanks very much for this post. I was struggling to get the sensor appear in Home-Assistant. Your note on the fact that HA never returns V_VAR1 on first use was very useful and pointed me in the right direction.

My modifications looked like this:

} else if (sendTime && !pcReceived) {
		// No pulse count value received from controller. Try requesting it again.
		request(CHILD_ID, V_VAR1);
    retryCount++;
		lastSend = now;
	} else if (retryCount >= 5 && !pcReceived) {
      //For some controllers, if you dont have any V_VAR1 stored node will not get an answer.
      //Try 5 times, then set V_VAR1 to 0 and update controller
    pcReceived = true;
    retryCount = 0;
    send(pcMsg.set(pulseCount));  // Send pulse count 0 value to gw
    double kWh = ((double)pulseCount / ((double)PULSE_FACTOR));
    send(kWhMsg.set(kWh, 4));  // Send kWh value 0 to gw
    lastSend = now;
  }

The whole sketch is here:

/*
   The MySensors Arduino library handles the wireless radio link and protocol
   between your home built sensors/actuators and HA controller of choice.
   The sensors forms a self healing radio network with optional repeaters. Each
   repeater and gateway builds a routing tables in EEPROM which keeps track of the
   network topology allowing messages to be routed to nodes.

   REVISION HISTORY
   Version 1.0 - Henrik Ekblad
   Version 1.1 - Peter Andersson added millis watt calculation if time between pulses > 1h

   DESCRIPTION
   This sketch provides an example how to implement a LM393 PCB
   Use this sensor to measure kWh and Watt of your house meter
   You need to set the correct pulsefactor of your meter (blinks per kWh).
   The sensor starts by fetching current kWh value from gateway.
   Reports both kWh and Watt back to gateway.

   Unfortunately millis() won't increment when the Arduino is in
   sleepmode. So we cannot make this sensor sleep if we also want
   to calculate/report watt value.

I've been building one of these pulse meters up, it seems to be working on the bench very nice. Just got to build a case and get a power supply of the Arduino. But I have designed a case to hold the LM393 sensor onto the meter. I removed the light sensor and re-soldered it flush to the board making it easier to mount on the meter. Its a simple box but works quite well.

The files are on thingiverse here

Hope this is useful.

@mfalkvidd Yes, that’s the one.

@mfalkvidd Thanks for the response. I was not trying to compile the SecurityPersonalizer sketch, I was trying to compile the Sensebender Micro example sketch, this apparently also needs the sha204xxx files. I copied these files over from the SecurityPersonalizer sketch and it works now. thank you.

I think sha204xxx files should also be put in the Sensebender Micro folder. Or some directions on the Sensebender Micro page on where to get these files.

Hi there,
Just received a couple of Sensebender Micro's, really excited to get them up and running. I'm trying to compile the sample code, but I can't find a library for the sha204, I'm getting the following error:

sha204_lib_return_codes.h: No such file or directory

Any idea how I can solve this please.
thank you.

@tbowmo Thats great, thank you. The URL seems to have changed.

Hello, really interesting in getting a few of these Sensebender Micros, but it does not seem to be available any more. Will they be coming back into stock?

@Matt-McAllister Hi there, I know this is an old topic, but I've been experiencing the same issue. the way I got around it is by putting a:

delay(500);

between the two presentation statements.

Hello all.

I'm just getting started with MySensors.org. I'm trying to flash my ProMini 3v3 with the Serial Gateway sketch with Arduino 1.6.4. on a Mac running OSX10.11.1

I have copied the MySensors library folder into user/documents/arduino/library

I have opened the SerialGateway sketch from File/Sketchbook/libraries/MySensors/SerialGateway

Upon verifying the sketch I get the following error in the Arduino IDE

SerialGateway.ino:52:26: fatal error: PinChangeInt.h: No such file or directory
compilation terminated.
Error compiling.

I cannot find the PinChangeInt.h file in the library. Can someone give me a clue on how I move forward. thank you.
