Re: [120] opentherm gateway

With the Remeha Tzerra and the Kiwi bought OTGW with esp8266 wifi to serial bridge the only value for that works without errors is VR=1. All the other values, especially the higher ones gave me all but error 03's.... Did you use a higher rated transformer and change out the 7805 for the Recom DC/DC...

Re: OTGW: No messages in the log..only timesatamp with OTGW:

it was the tx and the rx :oops: but can i now chance the switch and reset esp ? Glad you found that quickly. You can now put the switch back to uart and reset the button as many times as you want. Basically the reset button cuts the power and the controller boots up. I doesn't affect the firmware y...

Re: OTGW: No messages in the log..only timesatamp with OTGW:

The only difference I see is that I run esptool 1.2.1 and you run 1.3 dev.
I reckon you have resetted the wifi bridge a couple of times and put the switch in program mode.
Are you sure you have wired the TX to RX and RX to TX on the header of the wifi bridge?

MAX_CH Water Setpoint

Hi there, does anybody know what the MAX_CH Water Setpoint actually exactly does?...I was playing altering it from 80 to 75 degrees via domoticz sending a command to the OTGW which seems to work well. See pictures. I reckon it's a sort of Maximum water temperature of the central heating system as th...

Re: OTGW: No messages in the log..only timesatamp with OTGW:

Sure what kind of setup are you running? I have a raspberry PI 3 on which I run domoticz beta (jessie image). I had to install python 2.7 and pip first on order to install the esptool / bootloader utility which actually does the flashing. You also need a USB to serial cable to connect the wifi to se...

Re: OTGW: No messages in the log..only timesatamp with OTGW:

No, it wasn't although I had to sort out and install quite some stuff to get it all working. I used the ESP-12 wifi to serial bridge in conjunction with https://github.com/jeelabs/esp-link/releases/tag/v2.2.3 In order to get that firmware ON the ESP-12 I had to install this bootloader utility https:...

Re: Remeha Tzerra, Etwist, OTGW, ESP12 (esp8266)

Update: I got it all working...see pics of the setup.. Some notes to consider: The ESP-12 wifi to serial module sometime doesn't boot. The blue led keeps flashing when I power op the OTGW. When it's started it seems to work just fine. No connection drops or failures untill now I had to drop the volt...
