Opentherm firmware - Nodoshop version

This is a new firmware for the Nodoshop version of the OpenTherm Gateway.
It can be found here: https://www.nodo-shop.nl/nl/opentherm-gateway/188-opentherm-gateway.html
More information on this gateway can be read here: http://otgw.tclcode.com/

The features of this OTGW firmware are:

  • parsing the protocol on the NodeMCU (8266)
  • enable telnet listening (interpreted data and debugging)
  • send MQTT messages for every change (parsed OT message)
  • integrate with Home Assistant (and Domoticz)
  • serial interface on port 1023 for original OTmon application
  • a REST API (http:///api/v0/otgw/{id})
  • sending a MQTT command to OTGW (topic: OTGW/command)

To do:

  • InfluxDB client to do direct logging
  • OT command sending interface

Looking for the documentation, go here (work in progress):
