Hi
I've had a working CUL_MAX heating system for some time, so I have some ideas on how to put together an FHEM system
For a new project I have a 433MHz CUL and a Renkforce E0001PA temperature sensor. But I'm having trouble connecting them.
define CUL0 CUL /dev/ttyUSB0@38400 1234
attr CUL0 rfmode SlowRF
define WS0 CUL_WS 1
attr WS0 IODev CUL0
define TEMP_SENS1 SD_WS E0001PA
These commands are all accepted and CUL0 appears to be working (but not doing much)
The E0001PA seems to be classed as a weather sensor, so I've tried to connect CUL_WS (following the precedent of CUL_MAX), but despite turning debug up to 5, there's nothing going on.
Is the Renkforce Channel significant? Anyone know how often it broadcasts? Or is it pollable somehow?
Any ideas gratefully received

Do you have any indication that the protocol used by this gadget is understood/implemented in culfw?
I found your device mentioned here (https://fhem.de/commandref_modular.html#SD_WS), but SD_WS needs a SIGNALduino as the IO Module, and (AFAIK) a different firmware for the CUL.
Hi,
beside that good question from Rudi:
Which kind of CUL are you using? (e.g.
Busware CUL, nanoCUL, MapleCUL)
Maybe you could Flash a Signalduino Firmware to it, which depends on the Hardware.

Signalduino (Nano, ESP, ...), CUL (Busware, Nano, Maple, ...), Homematic (HM-MOD-UART-RPI, ESP, Maple, ...), LaCrosseGateway (LGW, ESP, ...), 1-wire, ESPEasy, Bravia, Yamaha, ...
Sorry for slow reply ...
I don't have direct evidence that the E0001PA is supported other than its messages are decoded by SD_WS. I was trying to find out what supports SD_WS and so thanks for mentioning signalduino. I'm using nanoCUL, so it seems that might be a possibility. Are there any examples of how to use signalduino and setting up sensors using SD_WS ?
I am however concerned that the E0001PA has a "channel" switch on the back with 3 channels which makes me think that one can only have three such sensors in a system.
What I would really like:
- low cost remote temperature sensor ( << 20EUR each )
- directly supported by FHEM
- up to 10 sensors can be in one FHEM system at the same time
- available ex stock from somewhere in the EU (e.g. Conrad) and ideally also in the US (so I can buy for my son who lives there without encountering import duty)
I have been unable to find anyone who describes such a device or how to set it up, so if you have ideas, they would be much appreciated. Thanks!
Hi,
lot of answers possible:
1) Build on your own (e.g. ESP8266 with DHT22 or DS18B20 sensors https://blog.moneybag.de/einfaches-wlan-thermometer-fuer-fhem-mit-nodemcu-ohne-loeten-teil-2/amp/ , or the MySensors https://www.mysensors.org/store/temperature)
2) or bought: LaCrosse Sensors are cheap. For example TX29 DTH-IT. They work fine with LaCrosseGateways (LGW here in the wiki https://wiki.fhem.de/wiki/LaCrosseGateway_V1.x )
or with the new CUL Firmwares (set CUL raw Nr1 or Nr2, refer to https://forum.fhem.de/index.php?topic=36565.0)
But there are lot of more answers, off course
