OTGW combined with Toon 2 thermostat
Posted: Thu Oct 26, 2023 3:09 pm
Two questions about OTGW:
- Can this, combined with a rooted Toon 2 thermostat, control the central heating boiler in terms of modulation?
- Can the OTGW also control an on/off boiler (just for my curiosity)?
The situation is as follows:
- Now I have an old central heating boiler that does not support OpenTherm.
- A rooted Toon2 controls this (on/off).
- In HomeAssistant I determine the average heat demand in % of the zones (by reading my EQ3-MAX trv's).
- When there is a heat demand from the zones, I control a zigbee relay that turns the boiler on.
The boiler will be replaced soon (probably in the spring) by a new one that does support OpenTherm.
Then I want to replace the zigbee relay with an OTGW and then let the boiler burn in a modulated manner based on the heat demand of the zones?
The end game:
- Toon controls the 'living room' zone and thus also controls the trv's temp settings there.
- There are 10 radiator knobs, each of which controls its own zone and feed back their heat demand to HomeAssistant.
- Based on the heat demand of the zones, HomeAssistant should decide to instruct the boiler to start heating if it wasn't already, using the OTGW.
Thanks in advance.
