Error on comfoconnect #68

Hi,

Just finish the wiring my ESP32 to a Zehnder Comfoair Q600 premium. The communication seems to work as i receive some value. But the comfoair show '' error on the comfoconnect network, check the wiring". As soon as the message appear, I receive updated value after a long interval (+- every 1 minute ) and the command are not working

Did someone already encounter this issue ?

Thanks

Hello @guillaum111 unfortunately i never encountered such issue. Assuming you followed wiring... what kind of other devices do you have connected to the bus?

guillaum111 commented 6 months ago

Sorry for the late answer, I had some health issue. I have nothing else connected to bus. When the error is not detected, it seems to work has i was able to send a command. I use another Can transceiver that i had in stock. maybe that's the issue. (https://www.amazon.com.be/dp/B0B1WW5XHV?psc=1&ref=ppx_yo2ov_dt_b_product_details). I will order the write transceiver. I also try with and without the bus Can bus resistor.

Problem solved, 2 of the 3 can transceiver i add are defect. With the good one it's working fine. I still replaced it by a wave shark to avoide issue
