Support Renkforce AOK-5055

[pjmpessers]

I had a Cresta DTX500 weather-station. The weather-station outside is for temperature, rain, windforce and wind-direction. After a day or something it picks up only one signal and it was saying low on battery. When i removed it from the roof it got broken. So i bought the Renkforce AOK-5055 from conrad with the same outside weather-station. The signal of this new one can be picked up by the display of the Renkforce AOK-5055 and the display of the Cresta DTX-500. Both are 433mhz and both where 1 meter of homey. From the old i removed the batteries. Homey sees the new one as a Alecto V1, but has many CRC check errors or says the temperature are out of range.

I installed the V1.2.2 wireless weather sensors app. My firmware is 1.5.6.rc-6

Can you help me?

On the picture on the left is the new Renkforce AOK-5055 and on the right the old Cresta DTX500. As you see the outside weather-station are the same.

By this file you see many temperature out of range errors.

I also have one debug-file where you can see that it had a good readout once. Where the humidity is good, but i needed a offset of -32.8 for the temperature. Also is it possible to support the rain, windforce and wind-direction of this weather-station?

Thanks for your help. stats1513150440025.zip

Thanks for the data. I will have a look at it. These messages are shorter (35 bytes) than what I would expect. Let me see if I can find a protocol description for them.

[nlrb]

BTW: the data of the Cresta DTX-500 - did you receive this with the Cresta or Alectov1 protocol?

[pjmpessers]

Thank you for your help.

Both. Cresta and Alectov1. The same thing is for the Renkforce AOK-5055. It also picks up Cresta and Alectov1.

Alectov1 gives me sometimes a good readout on both weatherstations. Just need to adjust the offset for temperature. But it only picks up one good readout a day. Cresta also gives a readout, but it is saying: "Invalid cresta message."

The renkforce does the same thing. Sometimes both also has a lacrosse TX2/3 readout by both. But never valid. Maybe it uses for every connected devices (Rain, Temperature, enz) different protocols?

I only can connect the one by devices with the ID 77 or TH77. This one is for temperature and humidity. I don't see the rain, enz.

When in need for more information, let me know. ;-)

[nlrb]

What I need to know is with which protocol the data was received reliably without CRC errors.

[pjmpessers]

That came from the Alectov1 with one good readout. That was on the Cresta DTX500 and the Renkforce OAK-5055.

[nlrb]

So with Alectov1 you got a good read-out with correct temperature as well?

[pjmpessers]

No. With Alectov1 it is more random. Most of the signal is invalid. But sometimes it picks up one good signal. And when the signal is picked up, the temperature readout is all over the place. A moment ago i needed to change the offset to -32.6. And the latest readout it was closer to the real temperature and i needed a offset of -2.2. The weatherstation is in this moment not outside, but in house. Also many cresta: "Not a valid cresta message." stats1513180945047.zip

[pjmpessers]

On this moment it found a second Alectov1 tempature/ humitidy sensor on ID 154. See JSON file. ;-) stats1513185971913.zip

[pjmpessers]

It seems on this moment that the readout on channel 2 (ID154) is much better. But still only temperature and humidity. No rain, windforce or wind-direction.

Update. Somehow it had a good readout for 10 minutes and now it's gone. Maybe it is set on a other channel?

[nlrb]

Ok, so in your case often the leading zero is missing in the data.

Can you make a change in app.json and install the code via the CLI?

Try changing line 605 to "minimalLength": 36, and see if that works better.

[pjmpessers]

I made the change, but somehow i couldn't sideload it. When i gave the command NPM install -g athom-cli i got a message npm WARN deprecated node-uuid@1.4.8: Use uuid module instead. com.weather-sensors-master.zip

[nlrb]

That is just a warning, you can ignore that.

[pjmpessers]

Oke. But i don't see wireless weather sensor by settings apps.:-(

[nlrb]

Can you make a recording of the signal with https://developer.athom.com/tools/signals ?

[pjmpessers]

Not a problem. And thank you for your support. recording.zip

[pjmpessers]

I Managed sideloading the app. I made the mistake of using athom project-install instead of athom project --install. On this moment (5 Minutes) no devices. stats1513202813265.zip

[pjmpessers]

This night it didn't find a device. But i see a invalid La crosse message. stats1513227574570.zip

[pjmpessers]

I hear of people having problem with the new 1.5.6-rc6 and/or 1.5.6-rc7 in the 433mhz. For me it looks that it doesn't make a difference. The same problem was with v1.5.5. My AYCT-102 klikaanklikuit remote on 433mhz still works without a problem. I now see that it also find a lacrosse TX2/3 sensor. Is it possible it uses more then one protocols combined together? For every sensor uses another protocol? Or is this just a false readout?

[nlrb]

I don't know yet which protocols your sensors use. I first want to have stable Homey firmware before I can investigate this further. There are definitely issues with 1.5.6.rc-6/7.

[pjmpessers]

I understand. I shall wait for a more stable firmware in the 433mhz band. 😉

[pjmpessers]

Still no luck with the firmware 1.5.6.rc-8. :-(

[pjmpessers]

Despite the new firmware update 1.5.6.RC-11 that would solve the problem with the wireless wheatherstations, the problem still excist. ;-)

[pjmpessers]

Also RC-13 doesn't solve it. Just a readout every +/- 3 hours or more.

The device does not use a known protocol. You can lookup my analytic: https://github.com/Rotzbua/reverse_engineering_weatherstation_conrad
