"hc1 program" not available when MQTT formating is set to "Nested in a single topic"; errors and warnings when parsing MQTT in Home Assistant

[lukcz]

Affected version: v3.4.4 Hardware:

Boiler | Condens 2500/Logamax/Logomatic/Cerapur Top/Greenstar/Generic HT3 -- | -- Thermostat | RC300/RC310/Moduline 3000/1010H/CW400/Sense 2

When MQTT formatting is set to "Nested in a single topic" there is no option to set value of "hc1 program" from Hoem Assitant. Seems like information about "hc1 program" is not published at all. Workaround is to switch format option to "As individual topics" - "hc1 program" published correctly then.

Additinally I can see some warnings and errosrs in home assistant log:

Thsnks! Indeed, it was my problem - it can be close.

Keep it in mind, with v3.5. the entities will change again (see #758, #759) and you need this procedure again.
