Maybe someone can help me out. I also use RF-Link on a Robotdyn ATmega2560+ESP8266. My plan is to use ESP-Easy as the Serial to MQTT bridge for RF-Link. I've tested all units with the code I found here ( see below (1) - it is in russian, but this is the only tutorial I found which is well structured...

I would like to move the the topic to an exiting thread in the ESP-Easy section.

I can say, that the unit is not defective. I use a 433 MHz RXB6 Receiver with an extra antenna. The range is great - I can see all things I wanted to see in the Serial Output of the the RF-Link Arduino Mega side. I tested all units with the code I found here ( see (1) - it is in russian): - esp8266 ...

Hi, I really hope that someone can help me out. I have the current version of ESP-Easy (alread tried older versions) and the current version of RF-Link on a Robotdyn ATmega2560+ESP8266. I can connect to the serial port of both devices and I get a valid output on both devices. On the Arduino part I s...

Very good. Thanks.

Ehh I don't understand your post (maybe lack of coffee, or sleep, or both ;) ) Nope, you were perfectly ok. I think I had too much coffee :roll: Is your question about whether someone tested the latest builds? (both v2.0 and Mega have nightly builds now) Yes, exactly. You wrote in another post: You...

You seem to have the "B" version of the sensor, which gives a "0" as S-value. Starting version dev-13, this will be supported, but you can also compile a version for yourself if you need it faster. I don't think the new dev-13 release will take long, since the last 2 days, a lot...

Just for information. The old power supply was rated at 5VDC/2A and the measurement was stable. The new one has the exact same values but works.

But I though about that today, I recently wasted my time in having a lot of issue on a project. I just solved them in changing my power supply : as this sensor is quite hungry during peak, check with a good power supply and a good cable Ah, timbiker. Cool. I just changed the power supply and now I ...

Strange. And you are both on "ESPeasy 2.0 dev 12"?

I use the precompiled image "ESPEasy_v2.0.0-dev12_dev_4096".

I use 5V - do you think I shall try 3.3V DC?

Yes, the red light is there. Under Arduino I get valid data. I switched rx and tx.

So, now I tried these combinations with no luck. Still CRC errors. I also tried a nodemcu now. Without luck. Sad.

Which software versions are you running? Does someone has a working MH-Z19 without the white plug / part on the backside?

Thank you.

I will try it. At the moment I have no access to the sensor. I'll give you feedback soon. Thank you so far.

TD-er wrote: ↑12 Dec 2017, 22:24 Are there other plugins active? Perhaps try to disable them, just for debugging.

No other plugins.

Has someone any idea - maybe someone has the same sensor?

Can I provide you with more data / information?

Just to get sure with your recommendiation - I checked again: RX -> D6 Tx -> D7 And Esp Easy 1st GPIO -> D7 2nd GPIO -> D6 Here I get: 376866 : MHZ19: Read error : CRC = 113 / 0 bytes read => 0/192/0/240/0/224/0/255/0/ 376866 : MHZ19: Shifted 2 bytes to attempt to fix buffer alignment 387109 : MHZ19...

RX -> D6 Tx -> D7 And Esp Easy 1st GPIO -> D7 2nd GPIO -> D6 Thanks. Already tried this combination. What pins did you use? And how do you power the sensor (what voltage)? I think I already tried all combination I could find in this forum / etc. I use 5VDC. At first from the Wemos and after that wi...

Hi Forum, I installed the developer version of ESPeasy 2.0 dev 12 to get my MH-Z19B to work. Unfortunately I can't get it to work :| Maybe someone can help me. Platform is Wemos D1 mini. I tried many PIN setups - I double-checked. I alway get the following output: 54264 : MHZ19: Unknown response: 0 ...
