Hi, I have sucessfully integrated the climate integration from HA and use the climate sensors. For setting temperature points, I use the set\_temperate call, so far OK when I use a fix number for the temperature. Right now, I want to set\_temeparture by using a flow variable which was set before (I call it "SollwertBar"). This does not work, just brings me some error. Who could help me on this, may just strugglig with JSOnata expression. my test flow:

```auto
[{"id":"8d4e585f02fee72c","type":"debug","z":"875324fd.7af898","name":"","active":true,"tosidebar":true,"console":false,"tostatus":true,"complete":"true","targetType":"full","statusVal":"payload","statusType":"auto","x":1584.2222328186035,"y":160.80000495910645,"wires":[]},{"id":"842731a923c2c56a","type":"api-call-service","z":"875324fd.7af898","name":"22.7 °C H-Lounge","server":"a11aa034.815b8","version":3,"debugenabled":false,"service_domain":"climate","service":"set_temperature","entityId":"climate.heizung_ventil_lounge","data":"{\"temperature\":\"$flowContext('SollwertBar')\"","dataType":"jsonata","mergecontext":"","mustacheAltTags":false,"outputProperties":[],"queue":"none","x":1401.9999504089355,"y":161.1110897064209,"wires":[["8d4e585f02fee72c"]]},{"id":"741f200c9452ae3e","type":"inject","z":"875324fd.7af898","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":1198.4444851345486,"y":162.000003390842,"wires":[["842731a923c2c56a"]]},{"id":"a11aa034.815b8","type":"server","name":"Home Assistant","version":1,"addon":true,"rejectUnauthorizedCerts":true,"ha_boolean":"y|yes|true|on|home|open","connectionDelay":true,"cacheJson":true}]

Your flow just consists of an inject node, an HA node and a debug node. Before I imported it I assumed you were picking up the variable from the context and passing it to the node. If you have configured it in the node then you may have to ask on an HA forum as very few (if any) here use HA.

Your jsonata has quotes around the $flowContext() remove them

```auto
{"temperature":"$flowContext('SollwertBar')"

should be
{"temperature":$flowContext("SollwertBar")}

```

[edit] Just spotted the missing } at end
