Re: OTGW monitor displays Bad Request messages

Doesn't work for me (with the web server on port 80)

None of the three proposed codes, entered via the Miscellaneous tab, work properly. Each time the command GW=1 gives the following response:
HTTP/1.1 400 Bad Request

For example:

OTGW monitor displays Bad Request messages

For example, when entering the command GW=1, the OT monitor gives the answer: HTTP/1.1 400 Bad Request

OTGW between eTwist and Elga Ace causes problems

I bought an OTGW at Nodo shop. Ready-made programmed and with WiFi. I placed this between the Remeha eTwist (without gateway) and the Elga Ace. The transistor 1 of the PCB immediately burned out, because the R-bus of the Elga apparently (sometimes) emits too high voltages and that R-bus does not aut...

Re: OTGW print between eTwist and Elga burns out

May I assume the measurements you reported were done with the boiler and thermostat disconnected? In that case the voltages you found are normal. The OTGW consists of 2 electrically isolated parts: The main part with the processor and thermostat interface, and the boiler interface. The boiler inter...

OTGW print between eTwist and Elga burns out

I bought an OTGW board with installed WiFi and firmware from Nodo shop. I hung this between my eTwist thermostat and my Elga Ace heat pump. But the PCB burned out at transistor 1. Nodo shop put the print back in order, after which the GTWO was reattached with the greatest care. Although just before ...

OTGW-print tussen eTwist en Elga brandt door

Ik heb een OTGW-print met geïnstalleerde wifi en firmware gekocht bij Nodo-shop. Deze heb ik tussen mijn eTwist thermostaat en mijn Elga Ace warmtepomp gehangen. Maar de print brandde door bij transistor 1. Nodo shop heeft de print weer op orde gemaakt, waarna met de grootste zorgvuldigheid de GTWO ...
