Initialization problem using P300 config in a Vitotronic 200

[delinchant]

Dear Bert,
Thanks a lot for you very powerful application
I'm trying to use it with a vitodens 222W which has a Vitotronic 200, type HO2B
I am using P300 configuration.
Wifi and webpage is OK
It starts initialization:
Optolink state: 0
Optolink state: 1 : try again every 0,5sec
Optolink state: 0
Optolink state: 1: try again every 0,5sec
Optolink state: 0
Optolink state: 1 : received 5 after 3 attempts
Optolink state: 2 : INIT (send {0x16, 0x00, 0x00})
Optolink state: 3 : waiting for ack, but no available data... so the program reset connection)
Optolink state: 0
Optolink state: 1 : the sequence is repeating infinitely !

Do you have any idea ?
Kind regards
Benoit

It could be a hardware problem. What type of optolink are you using? I supposed you build something yourself?

[delinchant]

Yes I do it by myself.But the communication seems good for the first states.It passes the reset ack only when I am putting the optolink on the boiler... -------- Message d'origine --------De : Bert Melis <notifications@github.com> Date : 26/01/2019 13:12 (GMT+01:00) À : bertmelis/esp8266-heating <esp8266-heating@noreply.github.com> Cc : Delinchant <benoit.delinchant@G2Elab.grenoble-inp.fr>, Author <author@noreply.github.com> Objet : Re: [bertmelis/esp8266-heating] Initialization problem using P300 config in a Vitotronic 200 (#1) It could be a hardware problem.

Yes, so the receive side works. It is not sure the transmit side works, as there is no response seen by the optolink.

I'm thinking how to test...

[bertmelis]

Maybe switch to the KW protocol, just for testing.

[delinchant]

Kw protocole stop the program at state 1.So I don't think it is the good one. -------- Message d'origine --------De : Bert Melis <notifications@github.com> Date : 26/01/2019 13:51 (GMT+01:00) À : bertmelis/esp8266-heating <esp8266-heating@noreply.github.com> Cc : Delinchant <benoit.delinchant@G2Elab.grenoble-inp.fr>, Author <author@noreply.github.com> Objet : Re: [bertmelis/esp8266-heating] Initialization problem using P300 config in a Vitotronic 200 (#1) Maybe switch to the KW protocol, just for testing. — You are receiving this because you authored the thread.

[bertmelis]

That still doesn't rule out a hardware problem. (if your heater can speak P300, it also speaks KW)

What type of LED/phototransistor did you use? Is it properly seeing the Vitotronic LED? Does the Vitotronic sees your LED? Is there any interference? Could be a lot of things...

As it get past state 1, your phototransistor works, but I don't know about your LED and I can't think of a simple way to test...
