I used ESPEasy_mega-20191208-19-PR_2825.zip downloaded from:

A test build for this PR: https://www.dropbox.com/s/iazr1ou3dmenf ... 5.zip?dl=0

I flashed the file ESP_Easy_mega-20191208-19-PR_2825_normal_ESP8266_4M1M.bin from the bin directory.
no problems with Wemos D1 mini

That would be nice.

after flashing, I enabled the MQTTT Domoticz controller and sets the new settings: Will Retain: false Clean Session true And of course I changed code in the Rules from: SendToHTTP api.thingspeak.com,80,/update?api_key=XXXX&field1=[DHT22#Temp]&field2=[DHT22#Hum]&field3=[Light#Lux]&fie...

I tested PR 2825 on ESP8266 Wemos d1 mini.
I flashed it with serial FlashESP8266.exe
No problems here.

MQTT with Thinsgpeaks works, great!!!

Oke I understand, RTC memory values can survive deep sleep.
Is there also a memory for users which survives a reboot, like the config parms.

Nice work
How can I test 2825

What do you mean with "the other plugin output values" ?

nice that you find a clue.
Indeed in MQTT.fx client the CleanSession is also set to true.

I use the a NPN sensor with a 8266 Wemos mini d1 to read my watermeter. The sensor is placed in the watermeterlid. Sensor see: https://benselectronics.nl/inductieve-proximity-sensor-npn/ It works great withe ESPmega. The NPN sensor needs 6 volts, so i use a 6 volts supply for both 8266 and NPN senso...

@ThomasB, The poking around for hours I recognize. Because sometimes I had a unique situation that only one message did arrive, I was happy for a short moment, but could not reproduce the situation afterwards. @TD-er I think the implementation of the ESP MQTT controller has been made too complex, pr...

Do you mean you are using the OpenHAB MQTT Controller and Publish rules to speak to Thingspeak? I didn't know that was supported, so learned something new here. Be sure to set the controller's Check Reply: Check Acknowledgement (as required by Thingspeak). Yes,I have to do so. Or is there another w...

Thanks I have the timeout on max 1000ms. In advanced settings the message interval at 15000ms. I tried several other settings without any success. With the MQTT.fx client, I can send MQTT messages to Thingsspeak without any problem, with QoS = 0 and retained = false Can you see the QoS and the Retai...

Great that SendToHttp in version 2820 has been Solved. I am testing now the ESP MQTT interface with Thingspeak. I found that the ESP MQTT interface has a similar problem. The MQTT messages are not received by Thingspeak. I send the following message with Rules to MQTT, using the ESP (openHAB) MQTT c...

I also just just tested the new version 2820. Great!! It communicates correct with api.thinkspeak.com. I saw also that Accept has been added, see my TCPlistener below. GET /update?api_key=XXXXXXXXXXXXXXXX&field1=20.40&field2=49.90&field3=96.67&field4=0 HTTP/1.1 Host: 192.168.1.11:300...

You mean in one request? Yes I mean in one request Concering the SendToHTTP request. I found out that there is no difference in the output data stream of ESP version 20191208 and version 20190809. They are both exactly the same (except for the User agent version date of course). The old version wor...

Same obscure problem here with version 20191130 en 20191208 (normal and test version). I want to sends a serie of 8 fields in one SendToHTTP request using Rules. It makes no difference using quotes or no quotes, that is not the problem here. On my local TcpListener tool, the GET request is send corr...
