Moving OT Monitor to ESP8266

Postby antst » Tue Jan 31, 2017 5:27 pm

It looks like ESP8266 is becoming choice for WLAN versions of OTGW. But everybody uses it as simple wifi-serial bridge, while ESP8266 has quite a hardware capabilities for its size.
And could run something similar to OT monitor (or at least MQTT) on it's own. reducing number of links in the chain (especially if OTM isn't used as stand-alone application but rather as daemon).

Does someone know any attempts to write specialised firmware for ESP8266 to use in conjunction with OTGW?

I guess I can just try to directly port TCL implementation of OTGW (without GUI of course, but with WEB interface), but I could spare some efforts if there are already something present.

In fact, I think I am going to choose simpler route.
I am going to take ESP8266-transparent-bridge as a base, and add to it MQTT client which can send/receive a bit more than OTM. This is task which is reasonably simple.

As a main feature, there will be time-out for an override values. If there is now new MQTT message for, lets say, 10 minutes, all of this is reset and thermostat gets a full control back.
