Hama wheater sensor not showing up in debug logs

---

Hey,

I set up Pimatic today using this tutorial: http://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more (thanks for writing the steps down (and for creating pimatic!)!)
Pimatic is running fine, however I´m not able to see any signals of the Hama TS33C (http://www.ebay.de/itm/Thermo-Hygro-Sensor-TS33C-Honeywell-Meade-Nexxtech-Hama-Hideki-Weather-Station-/231184523188) in the dubug output.

The signals of my Elro switch / remote are received and displayed correctly. Additionally I see ‘data: “PING”’ from time to time.

Do you have any advice how to get my sensor running? As far as I understand, I should see some kind of output even when the specific protocol is not supported yet.

Thanks,
Sebastian

hm… theres a similar problem with another device. normally there should be an output but, however, it seems to be that some devices are having rf protocols that homeduino isn’t able to pickup
which receiver do you use?

Hm
The receiver is this one: http://www.amazon.de/gp/product/B00OLI93IC

@Sebastian-Rösch As far as I can tell the receiver is not very good. I had the same and the results were disappointing for me (limited reach, some signals could not be decoded). See also http://forum.pimatic.org/topic/487/hardware-tip-433-mhz-receiver-for-pimatic/1 and http://forum.pimatic.org/topic/202/4-homeduino-433-mhz-sending-receiving-and-even-more

EDIT: The sender is OK. You may want to keep that

According to http://forum.pilight.org/Thread-hama-ts33c-temperature-hygrometer the TS33C sensor is using the Hideki/UPM protocol used by various OEM products such as TFA Nexus, Mebus, Irox, Irox-Pro X, Honeywell, Cresta TE923, TE923W, TE821W,
WXR810, DV928, Ventus W906. Another thread indicates the protocl has been reverse engineered, see http://www.wetterstationen.info/forum/entwicklerforum/tx-protokoll-offen-te923-cresta815-irox-(hideki)

The protocol document can be found here http://members.upc.nl/m.beukelaar/Crestaprotocol.pdf

As I am not familiar with all the details of homeduino I cannot tell whether or not the protocol is receptable by homeduino or even supported - possibly weather5?. Anyway, the receiver you have is poor and maybe the source of the problem. Make sure, the sensor is located close to the receiver - try at different distances.

Hey,
thanks for your help! I’ll check at different distances and get a proper receiver. Suggestions welcome (with delivery to Germany !

Thanks

for deliveries of 3400RF within Germany this could be your solution

Hello again!

I got the receiver from ebay @leader21 mentioned and now I´m the data of my temperature sensor. Thanks for the tip!

Unfortunately the protocoll seems to be unknown.

The sensor displays the temperature and humitity, has three channels and a low battery indicator. Additionally I can switch between °C and °F, but that might have no impact on the data that is sent.

Here are some sample logs with different temperatures and humidities:

(edit: I pasted weird data here, hope this is better now) What I see in the log file is this:

The latter part (01020102…) seems to be identical every time.
How does this relate to the protocol discription (http://members.upc.nl/m.beukelaar/Crestaprotocol.pdf) @mwittig posted?

@Sebastian-Rösch Do the temperature/humidity readings shows as part of wheather1 match with the values displayed by the sensor? 19% humidity appears to be too low …

No, temperature and humidity are both higher. The sensor was showing around 27°C and 70% humidity at that time.

Will check tomorrow.

So, right now the sensor shows 23,8°C and 64% humidity. It’s running on channel B.

This data is received:
424 2016 3972 9264 0 0 0 0 01020102020102020101020201010102010101010202020201010101010101020101020103"

Output:

weather5: { id: 218, lowBattery: false, temperature: -24.8, humidity: 80 }
weather1: { id: 179, channel: 2, temperature: 24, humidity: 18, lowBattery: true }

Both incorrect

Next update:
23,9°C and 64% humidity. It’s running on channel B.

424 2016 3968 9260 0 0 0 0 01020102020102020101020201010102010101010202020201010102010101020101020103

weather5: { id: 218, lowBattery: false, temperature: -24.8, humidity: 88 }
weather1: { id: 179, channel: 2, temperature: 24.1, humidity: 18, lowBattery: true }

So in weather1 the temperature increased correctly bei 0,1°C. lowBattery is definitely wrong. Humidity might have an offset, need to check for different values.

Next:
24,1 and 67%
424 2020 3960 9264 0 0 0 0 01020102020102020101020201010102010101010202020201010202010101020101010203

weather5: { id: 218, lowBattery: false, temperature: -24.8, humidity: 92 }
weather1: { id: 179, channel: 2, temperature: 24.3, humidity: 17, lowBattery: true }

Again, the delta of the temperature is fine for weather1. Humidity is different.
So, I’m guessing the temperature has an offset of +0,2 degrees? Or ist it possible that the broadcasted data is newer than the data shown on the sensor itself?

24,3°C and 63%, now on channel1
weather1: { id: 179, channel: 2, temperature: 24.5, humidity: 17, lowBattery: true }
428 2012 3964 9268 0 0 0 0 01020102020102020101020201010102010101010202020201020102010101020101010203"

–> switch of the channel had no effect on the displayed data.

@Sebastian-Rösch Are you sure the readings belong to your sensor? What happens if you remove batteries? If you still get readings for weather1 (id 179) it is another sensor in the neighborhood.

Damn, looks like you are right @mwittig . Still seeing those messages after removing the batteries.
So, no luck at all with my sensor?

@Sebastian-Rösch Maybe someone with more in-depth knowledge on the inner workings of homeduino can help. I have filed an issue for this - https://github.com/pimatic/rfcontroljs/issues/68

Thanks for your efforts! Hopefully someone picks up the issue.
